8 types of floor scales: characteristics, features, pros

Scales - a necessary and useful thing. On the market a variety of types and models of floor devices. They are endowed with all sorts of additions and besides weight determine other useful information.

Mechanical scales

mechanical scales Reliability and availability. The system is based on springs. The housing includes:

• Arm support in the form of four feet, sensing mass;
• Four of the metal arm;
• The plate, which is the upper arm support;
• Attached to the plate spring;
• Rocker with a dial and hands to control the spring tension.

There are mechanical devices in the following manner. When placing the weight on the horizontal platform is lowered down. At the corners of the metal protrusions are arranged with the groove. When driving in the shoulder lugs are niches and construction will be omitted.

In this case, each arm is supported at one end on the leg and moves only the opposite end. As a result, the plate is rejected by the spring and is measured.

Weight stack on four legs, which are interconnected in pairs. Spring - the heart of the mechanism. For accurate measurement of the parameter of the spring tension to be proportional to the mass, which weighed.

If this proportionality is not observed, there are inaccurate readings. The greater the weight, the more accurate readings, or vice versa.

For correction mechanism results in the adjustment screw is inserted, which twist and shift up or down indication. Quality measurement mechanisms after the removal of the goods return to a zero reading.

The increase in errors with increasing weight indicates a corrupted spring, which can not be mended.

Measurement of mechanical devices are determined by the scale in kilograms, sometimes it is divided by 500 grams. There are rare model with a flat-screen TV. They are determined by the spring deflection integrated sensor.

The accuracy of these devices is given in tenths or hundredths of a kilogram.

Mechanical divided into:

• medical (sports)
• shopping,
• industrial.

Differences medical devices exactly. Thanks to the two trimmer scales determined by accurate indications of mass, with a deviation of no more than 50 grams. This is important when monitoring patients during rehabilitation and other clinical situations.

Modern medical mechanisms are equipped with LCD screens and are connected to a personal computer. There are models with built Stadiometer that calculate typed excess weight or lack of.

Business models are similar to medical incredible precision, but different horizontal platform area. The housing is made of steel with a smooth surface.

In retail units high shear strength, so they are stable at rolling with large masses. Industrial floor machines with mechanical differ in size and weight is kept to a hundred tons.

Pros mechanical floor scales:

• Easy to use.
• Durability.
• Affordable price.
• Strength.
• Do not require replacement batteries.
• There are no special requirements for storage.

Cons mechanical floor scales:

• Old technology.
• Problems with accuracy.
• No additional features.

Electronic scales

Electronic balance the principle of operation is divided into three types:

1. Based on the springs.
2. On the basis of the special plates.
3. With the voltage sensor.

Cheap models are designed in the same way as mechanical, but the results are displayed on the built-in digital display. In devices with a disc or plate of metal is almost no mechanical components. They are like the electric mini-condenser.

When immersed them load occurs discrepancy disks, resulting in between changing electrocharge. This makes it possible to calculate the mass. Similar models have measurement errors of up to 300 grams.

Devices with a voltage sensor types are upgraded. The sensor is a metallic wire, a small size, which transmits an electric charge.

Under the influence of gravity tensioned wire, and the electric signal changes by measuring body weight. Accuracy of such devices is from 50 to 100 grams.

Electronic apparatuses are endowed with various additional functions. They retain all the latest weighing results, with several people.

Possible to calculate body mass, a certain percentage of fat and muscle, water and other substances in the body. Intelligent models determine who is weighed, and calculates the desired data.

Such devices warn the owner of the signal abnormalities in unwanted side body mass. Some devices are equipped with auto shutdown system.

Electronic devices show the result in kilograms or pounds. The models differ in their characteristics and on the use of rules. Not all models of electronic devices are applicable in areas with high humidity.

For such facilities selected devices with a waterproof casing and slip down. The surface they rippled.

The material from which they are made - plastic, metal, glass, wood. Reliable and robust design - a metal. Plus electronic devices in a variety of design and originality.

Electronic devices for measuring the masses do not suffer overload. They fail under excessive weight. In this case the sensors do not break out of order frame on which are fixed the main elements.

When fixing the housing is opened, the sensors is removed so as not to damage them.

Another distinguishing feature: the electrical devices may show different results on hard and soft surfaces. This is due to the fact that sensors are located at the edges, of different bend, depending on the hardness of the surface.

The deflection at which an accurate reading - on a flat hard surface, such as a bare concrete. When weighing on a soft carpet or other similar device surface gives wrong results due to the poor sag.

Advantages of electronic floor scales:

• Additional functions.
• Good accuracy.
• Colorful and interesting design.

Cons of electronic floor scales:

• Require careful storage, handling.
• They need a constant change of batteries.
• Price.

Glass bathroom scales

glass scales It looks very stylish and original, this users pay attention when buying. But, they have a number of features that should be taken into account by purchasing the balance of this material.

Glass even solid and hardened, brittle material, as compared with a metal or plastic. Glass floor models require special care when handling and storing. They can withstand the same load as the device of other materials.

But they are easy to break, dropping a heavy object on the surface. When moving too important to observe accuracy. They do not drop or bump. In glass mark of the device surface, they can see the slightest stain, even from contact.

But with careful care of the glass units look much more spectacular others. They better not be used in bathrooms or other areas where high humidity. Or choose a model with an embossed texture of the upper layer and the housing, protected from moisture.

Greater stability and strength of different designs with rubberized supports, which prevent sliding. High practicality possess those made of tempered glass.

The displays have a different design from the classic to the most unusual options in the form of large dials or speed display. Transparent glass devices fit perfectly into any space.

Impressive looking model with colorful images of landscapes, colors or patterns. Some models are complemented by glass inserts made of plastic or metal.

Diagnostic scales

diagnostic scales - the latest model of floor units, which determines not only the weight, 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.
• Level of basal metabolism.
• Rating physical development.
• Calorie consumption (daytime).
• Biological age (relative).

Define all this data helps the electrical signal that passes through the human body and analyzes the data. The signal is safe for health and life.

It served it from the platform, where there are special electrodes that respond to the touch of your feet.

Data analysis is based on pre-entered information on sex, age, height and level of physical activity of man. The integrated electronics evaluates the data by means of mathematical and physical calculations.

The device diagnoses the state of human health, on the basis of the received data and provides evidence to help improve health.

The level of the basal metabolic rate determines how much energy you need to rest, to ensure the normal operation of all systems and organs. The indicator shows 70% of energy (an approximate percentage), which consumes the body.

Based on this index, some models determine the biological age of a person. Depending on the ratio of muscle and body fat calculated rating of physical development.

This parameter varies and depends on how much energy people spend the day. Even with the same body weight, percentage of body fat and muscle can change for the better or the worse.

On the basis of data on sex, age and height is calculated the number of calories required for normal support of the organs, normal operation and activity.

Diagnostic devices are shown to people older than 16 years. In children, fast and rapid development, so the devices calculations designed for stable development in the adult organism, can be inaccurate in their objectivity.

To obtain accurate results it is necessary to weigh at least twice a day - morning and evening. To get up on the instrument should be barefoot. Using the machine is designed for several people. Data is entered on the number of profiles of three persons or more.

Scales with body composition analysis

Devices with analysis of body composition and the percentage of the weight of all components of the organism: weight, fat, liquid, bone and muscle mass and other substances. Scales operate using the electric signal passing through the body.

The percentage of adipose tissue, as well as other data, is determined on the basis of bioelectrical impedance. Each substance has conductivity inherent only to him. Based on this and concludes that the percentage of a particular component.

Body fat percentage will tell you whether you have a problem and help prevent further disease. Levels of internal fat indicates the status of the internal organs. This is the fat that surrounds the organs.

With an excess of abnormal functioning of the organism or components.

Water content is determined relative to the total weight, and indicates the total amount of liquid in the body. This indicator, which has an impact on all the other components.

The morning after sleep, the body loses water. During the day, the liquid distribution is also changing. Indicators of bone mass is not prone to such changes, they do not change.

But the percentage of muscle mass is variable and affects the rate of relative biological age. The more body fat and less muscle, the better.

Bathroom scale with automatic shut-off

Among a variety of features of modern floor devices for weighing one of the most practical and necessary is the automatic shutdown and startup. These devices save time and money.

Automatic shutdown and startup allow the user to not waste time on these procedures. The device itself responds to the touch and is automatically activated. The same happens after the removal of the mass. After some time, the scales are disabled themselves.

This defense mechanism, and battery savings, which is discharged prematurely. The parameters of the device can set the time. When enabled, if the device is not used for a specified time, they are automatically turned off.

Advantages of floor scales with automatic shut-off:

• Save time.
• Saving battery power.
• Convenience (no need to bend to switch on or off).

Scales with a load up to 150 kg

Floor measuring devices with a load of 150 kg - a classic mechanical and electronic devices. They are used:

• at home,
• in trade,
• in medicine.

Modern devices can withstand loads greater than 150 kg. But devices with a similar scale is still in demand. Most often these include devices that are bought for home use.

Household models with similar values ​​look as conventional floor units in the form of a flat plate with a display. They are electrical, mechanical rarely.

Vending machines up to 150 kg as shown in platforms with large dimensions. The display of such devices is presented in the form of individual boards. It is convenient for weighing cargo in bags, boxes and other tarakh.

In health care units with loads of up to 150 kilograms are used for weight control patients. But most modern clinics and hospitals are equipped with a load of 150 kilograms.

Floor scales for the whole family

The choice of instruments for home use depends on the purpose for which they are bought.

A great option - a device with additional functions of household equipment that will satisfy the needs of all family members, but it is not too difficult to use.

Choosing device, pay attention to the following functions:

• Memory.
• Switching on and off.
• User definition.
• Calculation of normal weight.
• Determinant of fat, muscle and water in the body.

The memory device stores the history of weighing each user, it is important when it is used by the whole family. With this feature, you can track changes in parameters. memory sizes are different, depending on the model.

Device with automatic switching off and on saving time and family budget. "Smart" appliances that may redefine the user, easy to use, if a family a few people and small children are present.

Calculation of the parameter of the human body weight will help control and maintain health. This function is used in the process of rehabilitation of patients is important when every gram of body.

The percentage of fat, water and muscle in the body - a useful information that will tell you which family members should pay more attention to health.

Choosing a machine for home, should give preference to models with a textured or roughened surface, stable and not slippery. This will protect against possible falls and injuries. In some sets of devices include anti-slip pads.

If the device is intended for use in the bathroom, on the street, in the sauna or any other damp places, it is best to choose a waterproof case. Practical for home use scales with height adjustable legs that can be easily moved.

When choosing a design, you should pay attention to the display size and brightness. For those with vision problems, fit model with a large wireless monitor. Another option - a device exchanging data with a personal computer.

There are such scales is expensive, but they help to monitor the status of each person in the family, preventing health problems.

choosing Scales for homeIt is important not to confuse the store mechanical devices with electronic. there are differences that are difficult to observe externally between them.

Mechanisms require self-installation, and electronic devices are used without prior manipulation. But they, unlike mechanical, require constant battery change.

Determine the device scales can acquire glass transparent model, which will definitely be electronic and will not hide any mechanical parts.

Using home interior measuring instruments can not forget about safety precautions. Do not:

• Overload. When you buy should read the instructions and know the permissible load. Above this figure the device breaks down and eventually stop working or will give wrong information.
• Expose the sharp strokes. This applies primarily to plastic and glass enclosure, they are easy to damage the blow.
• Putting the instrument foreign objects that spoil the surface or internal components.
• Shed water when the enclosure is protected from moisture.
• Open the case without special tools and knowledge.
• Place on a soft surface or how much. In the first case will an inaccurate result, in the second there is a risk of slipping and getting hurt.
• To get up on the platform with wet feet. This bodily injury or breakage of the device is not protected from the water.
• Use for cleaning housing aggressive chemicals or abrasives. This will erase pattern on the surface, or damage. Cleaning is best to use a damp, soft sponge or special tools.
• Allow the unit to young children.

Floor devices in rare cases indicate faults that are fixed in the home. If the wrong definition of a mechanical device body weight checks the zero position of the measuring direction.

If the failure is associated with a spring or the transfer mechanism, it is necessary to contact the service.

The electronic device with a similar fault confide batteries and change them. Invalid indicator and displayed due to improper installation of the device on uneven or soft surface or system failures.

Electronic devices are sometimes not included. In this case, it is necessary to check the integrity of the body and the possible presence of a defect. Perhaps the batteries are exhausted or are installed incorrectly. Electronic circuits is difficult to repair in the home, it is better to turn to the master.

Software failure sometimes occurs because of electromagnetic radiation, under which the device was turned on or if improperly. The device is switched off and transferred to another location.

If there is no reset scale - wedged body or in the mechanism of the device has foreign objects. The casing and restore its normal appearance.
