Rating of the best dynamometers for 2022

Various areas of human activity or production require the measurement of the impact of physical force. This indicator can be measured using a device called a dynamometer. With it, you can find out not only the force with which one object affects another, but also the gain. For the first time, such measurements were made using scales. Later, a device appeared with a spring that stretched a certain distance depending on the gravity of the object.

What is a dynamometer

Although this meter has several main types, which differ slightly in their principle of operation. But still, they all have a similar structure and common basic elements.

To begin with, it should be noted that each device has its own base, which can also be called a body. This part of the meter can be made of plastic, wood or any other material. A scale is always applied to the base, according to which measurements are taken. It also has a steel spring. The spring should have a hook with which it will be possible to fasten the spring to the body.

What are dynamometers

Modern devices for detecting the force of impact differ in their design and principle of operation. Therefore, they can be divided into three groups: mechanical, hydraulic and electrical.

So, mechanical measuring instruments, in turn, are of two types: lever and spring. In the first case, the applied force acts on the lever, thereby changing it. The degree of deformation after is recorded, and this value will indicate the magnitude of the force. In the spring version of the dynamometer, the force will act on the spring. And here, depending on which direction the force has, the spring will compress or stretch. The magnitude of the impact force will be proportional to the changes in the spring.

In a hydraulic device, the impact force will force the fluid out of the cylinder. By how much water was displaced from the cylinder, the magnitude of the force will be determined.

The electrical version of dynamometers consists of transducers. One of the sensors converts the impact force into a signal, then transmits it to the second sensor. The second sensor, in turn, captures and records the received signal. Piezoelectric, inductive, strain gauge resistance sensors are used as the first transducer.As a result, the final indicator is formed on the basis of the fact that the deformation of the transducer is directly proportional to the strength of the sensor signal.

Dynamometer Application

The scope of this measuring device is quite wide. Probably, not everyone can imagine that it is often used for measurements in everyday life. For example, it is necessary to measure the compression force of automatic systems. This includes elevators, doors of buses or subways, windows in a car. To many, this may seem like a futile exercise. But these automatic systems must comply with certain parameters and standards. Failure to follow these instructions may result in injury or accidents.

Do not forget about the use of a dynamometer in construction. With it, you can find out which operating conditions will be optimally suited for a particular design.

Do not forget about medicine. With the help of this device, the doctor can monitor the patient's recovery process, observe his muscles and endurance. A brush device is often used. It shows the forces of squeezing and unclenching the hand. This version of the meter is used not only in medicine, but also in such organizations as the Ministry of Emergency Situations, law enforcement agencies, military units, and the organization of martial arts.

Dynamometer Selection Criteria

Since this device has a wide scope, before buying a meter, you should know exactly what purpose this model is intended for. Each industry has specific requirements.

Pay attention to the functionality of the device and its modes of operation. Whether all available functions will be necessary for you when using. Due to the large number of functions, the price can be significantly higher, and you may not need them at all.Does it make sense to overpay?

You should also look at the smallest and largest measurement limits and the permissible error. Medical dynamometers can be designed for people of different ages. And, therefore, if the device is intended for children and adolescents, then the maximum limit will be of little importance. If a medical meter is purchased for home use, it is better to consult a doctor before buying. With it, you can choose the optimal model that will meet the requirements.

If you decide to take an electronic model of a force meter, then pay attention to the way it is powered. Battery-powered models can be used anywhere and taken on the road without worrying about finding outlets. In such models, the self-power off function will be very useful, when the device automatically turns off after a certain time, when not in use.

Conclusion

Hand-held dynamometers are considered to be particularly sought-after meters. Their presence is mandatory both in schools, sports sections, and in medical institutions. Checking the strength capabilities will prevent the occurrence of injuries from excessive load. Such checks should also be carried out among the employees of the company, where the manifestation of physical force is necessary. In hospitals, medical staff will be able to assess the degree of recovery of a patient after an injury. It is also important that children measure strength indicators on special children's devices in order to avoid errors.

When choosing between an electronic and a mechanical model, it is better to give preference to the first option. Since all models are in the same price category, but the electronic device produces a smaller error.And if such a device is used at home, then it is possible to observe the dynamics, saving the results to the integrated memory.
