An electronic torque measuring device is - simplified - a portable tool consisting of a torque sensor, an electronic card, software and a display. The torque sensor is an electronic system for converting a torque into an electrical signal. The applied torque deforms the strain gauges. These strain measurement devices converted the deformation (mechanical load) into an electrical signal. The software and electronics in the device show the electrical voltage with a torque value on the display.
The main units of measurement are the Newton.meter (Nm) and the pound per square inch (lbin). The maximum is the result most often sought in torque measurements: this allows it to be determined whether a product is compliant or not. Some examples of torque measurements: on screws, fixings, fasteners, torsion springs, etc. Furthermore, more demanding tests, such as dynamic torque tests on motors, can be performed.

What is a torque meter and what is it used for?
A torque meter is an instrument used to measure the torque or rotational force exerted on an object. It normally consists of a shaft or handle to which the torque is applied and a measuring instrument that displays the value of the torque in a specific unit of measurement.
Torque measuring devices are used in various areas of application, particularly in industry and mechanical engineering. They are useful for ensuring that certain screw connections, such as in vehicles or machines, are correctly tightened. By measuring the torque, it is possible to check whether the bolts or nuts are properly tightened to ensure optimum performance or safety.
In addition, torque measuring devices are also used in quality control to ensure that products meet certain standards and specifications. They can also be used in the development and design of new products to test the load-bearing capacity and functionality of components.
Overall, a torque meter is an important tool for measuring torque force and ensuring that bolted joints and other rotating components are correctly tightened.

How does a torque meter work?
A torque meter is used to measure the torque or rotational force exerted on an object. It consists of a torque sensor cell that is connected to a display unit or a connection option to a computer.
The torque sensor cell normally contains strain gauge technology, where the strain gauges expand or contract under load. These changes are converted into electrical signals, which can then be measured and displayed.
The strain gauges are mounted on a metal rod or shaft that twists when the torque is applied. When the torque is applied, the twisting of the metal rod causes a change in the strain gauges, which leads to a change in the electrical resistance.
The electrical signals generated by the strain gauges are then amplified and converted into a digital display or computer interface. The display unit then shows the measured torque. In some cases, the measuring device can also provide a means of transferring the measured torque to a computer for further analysis or recording.
Some torque meters also have an adjustable scale that allows users to calibrate the meter to improve the accuracy of the measurements.
It is important to note that torque measuring devices are available in different versions and may be suitable for different applications. For example, some may be designed for low torques in the electronics industry, while others are designed for high torques in the automotive industry.

How accurate are torque meters?
Torque meters are usually very precise and accurate instruments that are used to measure the torque exerted on a component or part. They can be used to measure the torque of motors, machines, screws or other rotating parts.
Modern torque measuring devices generally use strain gauges that are attached to the surface of the measuring device. When the torque is applied to the device, the shape of the strain gauge changes and generates an electrical voltage. This voltage is then converted into a torque and shown on a digital display.
The accuracy of torque measuring devices can vary depending on the model and manufacturer. High-quality and calibrated devices can have an accuracy of ±1% or better. However, it is important to note that accuracy can also depend on factors such as the correct use and handling of the device.
It is advisable to calibrate torque measuring devices regularly to ensure that they continue to provide accurate measurements. This can be carried out either by the manufacturer itself or by a specialized calibration facility.
