Rating of the best dynamometers for 2024

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

What is a dynamometer

Although this meter has several basic 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 case. This part of the meter can be made of plastic, wood, or any other material. The base is always marked with a scale according to which measurements are taken. There is also a steel spring. The spring should have a hook that can be used to secure the spring to the body.

What are the 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 is then 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 be compressed or stretched. The magnitude of the impact force will be proportional to the changes in the spring.

In a hydraulic device, the force of action will force the fluid out of the cylinder. The amount of force will be determined by how much water has been displaced from the cylinder.

The electrical version of dynamometers consists of converters. 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. As the first transducer, piezoelectric, inductive, strain gauge resistance sensors are used. As a result, the final indicator is formed on the basis 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 required to measure the compressive force of automatic systems. These include elevators, bus or subway doors, and car windows. This may seem like a useless exercise to many.But these automatic systems must comply with certain parameters and standards. Failure to do so can lead to injury and accidents.

Do not forget about the use of a dynamometer in construction. With its help, you can find out what operating conditions will be optimal for a particular design.

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

Dynamometer selection criteria

Since this device has a wide range of applications, before buying a meter, you should know exactly for what purpose this model is intended. Each field of activity has specific requirements.

Pay attention to the functionality of the device and its modes of operation. Whether all the 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 limit and the permissible error. Medical dynamometers can be designed for different ages of people. 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 purchasing. With its help, it will be possible to select 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 having to worry 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 especially popular meters. Their presence is mandatory both in schools, sports clubs, and in medical institutions. Strength testing will help prevent overuse injuries. Such checks must also be carried out among company employees, where the manifestation of physical strength is necessary. In hospitals, medical staff will be able to assess the patient's recovery from an injury. It is also important that children measure their power indicators on special children's devices in order to avoid errors.

When choosing between electronic and mechanical models, it is better to give preference to the first option. Since all models are in the same price range, the electronic device gives out less error. And if such a device is used at home, then it is possible to observe the dynamics, storing the results in the integrated memory.
