Dynamometer

Dynamometers are some kind of load cells used in the force and strain measurements in the direction of tensile.

There are models with built-in display (FM) or wireless communication modules (DMA) that can be connected to external displays wirelessly.

In addition, pin type load cells omega-type screw locks (eyebolts) are produced by mounting the eyebolt load pin, which we call the Load Shackles in the pull direction are also available.

Kobastar is one of the leading manufacturers of 3 different models in the world with 100% Turkish guarantee.

Compared to other crane scales, Tension dynamometers are lighter, easier to carry and can reach higher capacities.

All the Tension dynamometers and Load Shackles that we have produced have CE certificates which certifies the conformity with 2006/42 / EC standards.

What is a Dynamometer?

Dynamometers are load cells used to measure force and strain in the tensile direction. These devices are used to measure the strength, flexibility, hardness and other physical properties of materials by directly measuring force. Dynamometers are used in many industrial, medical and sports fields.

Working Principle of Dynamometers

Dynamometers have a special structure that shows deformation according to the effect of force. The force in the tensile direction on the dynamometers triggers the deformation of the load cell. This deformation creates a strain that can be measured on a predetermined scale. Thus, the relationship between force and strain is used to accurately calculate the measurement result.

Application Areas of Dynamometers

  1. Material Testing: Dynamometers are used to measure the durability, flexibility, hardness and other physical properties of materials. These properties are important to determine the quality and durability of materials used in various industrial fields.
  2. Industrial Applications: Dynamometers used for industrial applications are used to ensure that cranes and lifting equipment carrying heavy loads are operating correctly. These devices are frequently used in industrial applications due to their high measurement sensitivity, resistance to environmental influences and rapid measurement results.
  3. Medicine: These products are used to measure muscle strength. This property is used in medical rehabilitation and physiotherapy processes. Dynamometers are also used to detect muscle weakness or functional disorders.
  4. Sports and Fitness: Dynamometers are used to measure the strength and endurance of athletes. These devices are used to optimize training programs and improve athletes’ performance. Dynamometers are also used in places like fitness centers and gyms.

Types of Dynamometer

  • Tension Type: Tension type dynamometer measures the tension applied to the material. These devices are used to measure the strength and flexibility of the material.
  • Compression Type: Compression type dynamometers measure the force resulting from the compression of the material. These devices are used to measure the hardness and density of the material.
  • Capacitive Type: Capacitive type dynamometer measures the change of capacitance between two parallel plates. This change occurs due to the effect of the force applied to the material. These devices are used to measure the elastic modulus of the material.
  • Magnetic Type: Magnetic type dynamometers measure the magnetic field on the material. These devices are used to measure the changes that occur when the force applied to the material affects the magnetic field.

Features 

  • Measurement Accuracy: The measurement sensitivity of dynamometers determines the accuracy of the device. High precision dynamometers ensure that measurement results are more accurate and reliable.
  • Measurement Range: The measurement range of dynamometers determines the minimum and maximum force that the device can measure. This feature should be selected according to the properties of the material to be measured.
  • Ease of Use: Dynamometers should be easy to use and measurement results should be obtained quickly. Additionally, detailed information should be included in the device’s user manual.
  • Durability: Dynamometers are frequently used under heavy loads and exposed to environmental influences. Therefore, it is important that the device is durable and has a long service life.

Calibration of Dynamometers

Dynamometers need to be calibrated periodically to provide accurate measurement results. Calibration is a process to check the measurement accuracy of the device and adjust it if necessary. Calibration is done using known values of the force to be measured.

Calibration of dynamometers must be done by a calibration laboratory or an authorized service. The calibration process should be performed at different time intervals depending on the measurement range of the device. For example, high-precision dynamometers must be calibrated more frequently.

In summary, dynamometers are load cells used to measure force and strain in the tensile direction. There are different types: voltage, compression, magnetic and capacitive. Features of dynamometers include measurement accuracy, measurement range, ease of use and durability. Dynamometers are used in many different application areas, for example the automotive industry, aerospace industry, construction and building materials, food industry, sports and fitness. Dynamometers need to be calibrated periodically to provide accurate measurement results.
