8 types of floor scales
Floor scales are a necessary and useful item. There are a variety of types and models of outdoor appliances on the market. They are endowed with all sorts of additions and, in addition to weight, determine other useful information.
Mechanical floor scales
Mechanical scales are reliable and affordable. The system is based on springs. The body contains:
- Support levers in the form of four legs, perceiving the mass;
- Four arms made of metal;
- The plate on which the shoulder supports go;
- A spring attached to the plate;
- Rocker arm with a dial and an arrow to control the tension of the spring.
Mechanical devices operate according to the following principle. When the mass is placed on a horizontal platform, it goes down. There are metal protrusions with a groove at the corners. When moving, the protrusions enter the niches of the shoulders and the structure lowers.
In this case, each shoulder rests with one end on the leg and only the opposite end moves. As a result, the plate is deflected by the spring and the measurement takes place.
The mass is summed up on four arms, which are interconnected in pairs. The heart of the mechanism is the spring. For an accurate measurement of a parameter, the extension of the spring must be proportional to the mass being weighed.
If this proportionality is not observed, inaccurate readings occur. The greater the weight, the more accurate the readings, or vice versa.
To correct the results, a tuning screw is built into the mechanism, which is twisted and shifted the readings up or down. Quality measuring mechanisms after the removal of the load returns to zero reading.
An increase in error with increasing weight indicates a damaged spring that cannot be repaired.
Measurements of mechanical devices are determined on a scale in kilograms, sometimes it is divided into 500 grams. There are rare models with an LCD screen. In them, spring deflections are determined by a built-in sensor.
The accuracy of such devices is given in tenths or hundredths of a kilogram.
Mechanical are divided into:
- medical (sports),
Differences of medical devices in accuracy. Thanks to two trimming scales, accurate weight readings are determined, with a deviation of no more than 50 grams. This is important when monitoring patients during the rehabilitation period and in other clinical cases.
Modern medical mechanisms are equipped with LCD displays and are connected to a personal computer. There are models with built-in stadiometers that calculate the gained excess body weight or lack.
Trading models are similar to medical ones with incredible accuracy, but differ in the area of the horizontal platform. The body is made of steel with a flat surface.
Trading devices have high transverse strength, so they are stable when rolling with large masses. Industrial floor-standing devices with a mechanical device differ in size and can withstand masses of up to one hundred tons.
Advantages of mechanical floor scales:
- Easy to use.
- Affordable price.
- Does not require battery replacement.
- There are no special storage requirements.
Cons of mechanical floor scales:
- Old technology.
- Problems with accuracy.
- There are no additional features.
Electronic floor scales
Electronic scales according to the principle of operation are divided into three types:
- Spring based.
- Based on special plates.
- With voltage sensor.
Cheap models are arranged in the same way as mechanical ones, only the results are displayed on the built-in digital display. In devices with discs or metal plates, there are almost no mechanical components. They are like an electric mini capacitor.
When the load is immersed on them, the disks diverge, as a result, the electric charge between them changes. This allows you to calculate the mass. Such models have measurement errors up to 300 grams.
Devices with a voltage sensor are upgraded types. The sensor is a metal wire, small in size, which transmits an electrical charge.
When gravity is applied, the wire is stretched and the electrical signal changes, measuring the mass of the body. The error of such devices is from 50 to 100 grams.
Electronic devices are endowed with various additional functions. They save all the latest weighing results, and several people at once.
It is possible to calculate body weight, determine the percentage of fat and muscle, the amount of water and other substances in the body. Intelligent models determine who is being weighed and calculate the right data.
Such devices warn the owner with a signal about body weight deviations in an unnecessary direction. Some devices are equipped with an auto-off system.
Electronic devices show the result in kilograms or pounds. Models differ in their features and rules for use. Not all models of electronic devices are applicable in rooms with high humidity.
For such premises, devices with a waterproof case and an anti-slip bottom are selected. Their surface is corrugated.
The material from which they are made is plastic, metal, glass, wood. Reliable and durable metal construction. Plus electronic devices in the variety and originality of design.
There are devices with displays separate from the platform, with large or small dials, or other variations in the design of readings.
Electronic devices for measuring mass do not tolerate overload. They fail under unbearable weight. At the same time, the sensors do not break, the skeleton on which the main elements are fixed fails.
When repairing, the case is opened, the sensors are removed so as not to disable them.
Another distinguishing feature: electrical devices can show different results on hard and soft surfaces. This is due to the fact that the sensors located at the edges flex differently, depending on the hardness of the surface.
Deflection, at which accurate readings are on a flat hard surface, for example, on bare concrete. When weighing on a soft carpet or similar surface, the instrument will give incorrect readings due to poor deflection.
Advantages of electronic floor scales:
- Additional functions.
- Good accuracy.
- Colorful and interesting design.
Cons of electronic floor scales:
- Requires careful storage and handling.
- Needs constant battery replacement.
Glass floor scales
Glass scales look very stylish and original, users pay attention to this when buying. But, they have a number of features that should be considered when purchasing scales from this material.
Glass, even strong and hardened, is a brittle material compared to metal or plastic. Glass floor models require special care during use and storage. They withstand the same loads as devices made of other materials.
But they are easy to break by dropping a heavy object on the surface. When moving, it is also important to be careful. They cannot be dropped or hit. Glass devices have a soiled surface, the slightest spots are visible on them, even from contact.
But with careful care, glass devices look much more spectacular than others. It is best not to use them in bathrooms or other areas where there is high humidity. Or choose models with a relief texture of the top layer and a case protected from moisture.
Designs with rubberized stands that prevent slipping are distinguished by greater stability and durability. Those made of tempered glass have high practicality.
Of the positive qualities of glass devices, brightness, colorfulness and originality of design stand out. They look very stylish in any interior.
The displays have a different design, from classic options to the most unusual in the form of large dials or speed displays. Transparent glass devices fit perfectly into any space.
Models with colorful images of landscapes, flowers or patterns look spectacular. Some glass models are complemented by plastic or metal inserts.
Diagnostic floor scales
Diagnostic scales are the latest model of outdoor devices that determine not only the mass, but also the composition of the human body. They are showing:
- total body weight.
- How much body fat (as a percentage).
- The percentage of internal fat.
- The amount of water.
- muscle mass.
- Bone mass.
- Basal metabolic rate.
- Rating of physical development.
- Calorie intake (daily).
- Biological age (relative).
An electrical signal that passes through the human body and analyzes the received data helps to determine all this data. The signal is safe for health and life.
It is served from a platform where special electrodes are located that react to contact with the feet.
Data analysis is based on pre-entered information about a person’s gender, age, height, and exercise level. Embedded electronics analyzes data through mathematical and physical calculations.
The device diagnoses the state of human health, based on the data received and gives indications that will help improve health.
The level of basal metabolism determines how much energy is needed at rest to ensure the normal functioning of all human systems and organs. The indicator displays 70% of the energy (approximate percentage) that the body consumes.
Based on this indicator, some models determine the biological age of a person. Depending on the ratio of muscle and fat, the rating of physical development is calculated.
This parameter changes and depends on how much energy a person spent per day. Even with the same body weight, the percentage of fat and muscle can change for better or worse.
Based on data on gender, age and height, the number of calories needed to properly support the functioning of organs, normal performance and activity is calculated.
Diagnostic devices are shown to people over 16 years of age. Children develop rapidly and vigorously, so calculations for devices designed for developmentally stable adults may be inaccurate in their objectivity.
To get accurate results, you need to weigh yourself at least twice a day – in the morning and in the evening. Step on the device with bare feet. Use of the device is designed for several people. Data is entered for the number of profiles from three persons or more.
Floor scales with body composition analysis
Devices with the analysis of body composition determine the percentage and mass of all components of the body: weight, fat, fluid, bone and muscle mass and other substances. Scales work with the help of an electrical signal passing through the body.
The percentage of adipose tissue, like other data, is determined according to the principle of bioelectrical resistance. Each substance has an electrical conductivity inherent only to it. Based on this, a conclusion is made about the percentage of one or another component.
The percentage of body fat will tell you if you have problems and help you avoid future diseases. The level of internal fat indicates the condition of the internal organs. This is the fat that surrounds the organs.
With an excess, the normal functioning of the body or components is disrupted.
The water content is determined relative to the total mass and indicates the total amount of fluid in the body. This is an indicator that affects all other components.
Water is the main component of a person and its deficiency or excess in the body causes changes in the organs. The readings of the water content change during the day depending on when the person weighed himself.
In the morning, after sleep, the body loses water. Throughout the day, the distribution of liquid also changes. Bone mass indicators are not prone to such changes, they almost do not change.
But the percentage of muscle mass is variable and affects the indicator of relative biological age. The more muscle and less fat, the better.
Floor scales with auto-off
Among the variety of functions of modern floor weighing devices, one of the most practical and necessary is automatic switching off and on. These devices save time and money.
Automatic switching off and on allows the user not to waste time on these procedures. The device itself reacts to contact and automatically turns on. The same happens after the removal of the mass. After a while, the scales turn off by themselves.
This is both a protective mechanism and saving the battery, which will not be discharged prematurely. You can set the time in the device parameters. When turned on, if the device is not used for a specified time, they will automatically turn off.
Advantages of floor scales with auto-off:
- Saving time.
- Save battery power.
- Convenience (no need to bend over to turn it on or off).
Floor scales with a load of up to 150 kg
Floor measuring devices with a load of up to 150 kilograms are a classic version of mechanical and electronic devices. They apply:
- at home,
- in trade,
- in medicine.
Modern devices can withstand loads more than 150 kilograms. But devices with a similar scale are still in demand. Most often, these include devices that are purchased for use at home.
Household models with similar values look like ordinary floor standing devices in the form of a flat plate with a display. They are electrical, rarely mechanical.
Vending machines up to 150 kilograms are presented in the form of platforms with large dimensions. The display of such devices is presented in the form of separate scoreboards. This creates convenience when weighing cargo in bags, boxes and other containers.
In medical institutions, devices with a load of up to 150 kilograms are used to control the body weight of patients. But most modern clinics and hospitals are equipped with equipment with a load of more than 150 kilograms.
Floor scales for the whole family
The choice of measuring instruments for home use depends on the purpose for which they are bought.
An excellent option is a device with additional features for home use that will satisfy the needs of all family members, but at the same time not too complicated to use.
When choosing a device, you should pay attention to the following features:
- Turning on and off.
- User definition.
- Normal weight calculation.
- Determinant of fat, muscle, water in the body.
The memory of the device remembers the history of weighing each user, this is important when the whole family uses it. With this function, you can track parameter changes. The amount of memory varies depending on the model.
The device with automatic shutdown and inclusion saves time and the family budget. “Smart” devices that can determine the user themselves are convenient if there are many people in the family and there are small children.
Calculation of the normal parameter of a person’s body weight will help to control and maintain health. This function is also used in the process of rehabilitation of patients, when every gram of the body is important.
The percentage of fat, water, muscle in the body is useful information that will tell you which family member should pay more attention to health.
When choosing a device for the home, you should give preference to models with a textured or rough finish, stable and not slippery. This will protect against possible falls and injuries. Some devices come with anti-slip pads.
If the appliance is intended to be used in a bathroom, outdoors, sauna or other damp places, it is better to choose a waterproof housing. Practical for home use scales with adjustable height legs that are easy to move.
When choosing a design, you should pay attention to the display size and brightness. For those who have vision problems, a model with a large wireless monitor is suitable. Another option is a device that communicates with a personal computer.
Such scales are expensive, but they help to control the condition of each person in the family, preventing health problems.
When choosing scales for your home, it is important not to confuse mechanical devices with electronic ones in the store. There are differences between them that are difficult to notice externally.
Mechanisms require self-installation, and electronic devices are used without prior manipulation. But they, unlike mechanical ones, require a constant change of batteries.
You can determine the device of the scale by purchasing glass transparent models that will definitely be electronic and will not hide any mechanical parts.
When using floor measuring instruments at home, one must not forget about safety precautions. It is forbidden:
- Overload. When buying, you should read the instructions and find out the allowable load. If this indicator is exceeded, the device fails and eventually stops working or gives incorrect information.
- Subject to sharp blows. This applies primarily to plastic and glass cases, they are easily damaged by impact.
- Place foreign objects on the appliance that damage the surface or internal components.
- Spill water if the case is not protected from moisture.
- Open the case without special tools and knowledge.
- Install on a soft or hard surface. In the first case, an inaccurate result will come out, in the second, there is a risk of slipping and getting injured.
- Get up on the platform with wet feet. This is fraught with injury or damage to the device, which is not protected from water.
- Use harsh chemicals or abrasives to clean the case. This will erase the pattern on the surface or damage it. For cleaning, it is better to use a damp soft sponge or special products.
- Allow small children to use the device.
Floor-standing appliances in rare cases show malfunctions that can be fixed at home. If the mechanical device determines the body weight incorrectly, the zero position of the measuring needle is checked.
If the breakdown is related to the spring or the transmission mechanism, you must contact the service.
In an electronic device, in case of such a malfunction, the batteries are checked and changed. An incorrect indicator is also displayed due to incorrect installation of the device on an uneven or soft surface, or system failures.
Electronic devices sometimes do not turn on. In this case, it is necessary to check the integrity of the case and the possible presence of defects in it. The batteries may be dead or not installed correctly. Electronic circuits are difficult to repair at home, it is better to contact the master.
Software failure sometimes occurs due to electromagnetic radiation, under which the device has fallen or if it is not turned on correctly. The device is turned off and moved to another location.
If the scale does not reset to zero, the case is jammed or there are foreign objects in the device mechanism. The hull is dismantled and restored to its normal appearance.
