Electronic and mechanical scales floor. Which ones to choose?

Mechanical floor scales recent steelalmost every home. The rapid pace of life, malnutrition lead to an increase in body weight. This is known to everyone, and therefore you need to regularly monitor the weight of your body in order to timely score an alarm, change your diet or go to sports. And to future mothers without them simply can not do.

What are floor scales?

1. Mechanical.The main measuring tool in them is a spring that stretches under the load and rotates the pointer of the scale or the scale itself (depending on the design) is directly proportional to the weight of the object. They are "reset" using a special wheel that is located at the bottom. Scales outdoor mechanical home usually have a division price of 1 kg, although there are also with 0.5 kg.
2. Electronic. By the principle of their operation, the first electronic scales did not differ from the mechanical ones, the same spring, only the result was displayed on a digital display.

In the design of modern electronic scalestwo metal discs come in, and as a result, something like an electric capacitor is formed. Under the influence of the load, the distance between the plates changes, changing the electric charge and, accordingly, the readings of the scales. Even more modern models use a voltage sensor, which is a thin metal wire that is subject to electrical current. If we place a weight on the scale, the tension of the sensor changes, and consequently the magnitude of the electric signal passing through it, which is displayed on the board. This design is completely devoid of mechanical parts, and all measurements are made by electronics.

All types of scales have their strengths and weaknesses.parties. Floor scales are less accurate and much simpler in construction. Therefore, they are much cheaper than electronic ones, which in their functionality are more and more close to personal computers. In addition to the usual measurement of weight, electronic scales can determine the ratio of the amount of fluid, muscle and fat mass, remember the dynamics of changes in weight, and even calculate the optimal weight for each individual person.

Tips and recommendations for the selection and operation of scales

• Choosing electronic or mechanical scalesfloor, it is necessary to pay attention to the measurement system used in them. Scales produced in some countries, such as the UK or the United States, often measure weight in pounds instead of kilograms, and therefore you need to make sure that they are able to switch to our usual measurement system.
• If you plan to place the scales in a room with high humidity (bathroom or sauna), it is better to choose scales in a moisture-proof case.
• It is advisable to purchase scales with a rough or corrugated surface.
• Scales must be resistant. Some models have a mechanism for leveling them on an uneven surface. Otherwise, the error of their measurement can reach ten percent.
• Electronic or mechanical floor scales in a metal case are more reliable and durable than plastic ones.
• Before you buy a scale, you need to check the accuracy of their measurement. This is best done if you know your exact weight in advance, or you can weigh the packaged goods.
• Checking the mechanical floor scales, you need to quickly briefly click on them, and then release them sharply as well. At the same time, the scale arrow should be quickly and accurately set to zero.

На современном рынке выбор весов очень большой, а therefore, in any case, it is up to you to decide which floor scales are best to buy - mechanical or electronic. It all depends on the conditions, needs and, of course, financial capabilities.
