Pressure sensors
Pressure sensors (also known as strain gauges) are devices that convert mechanical energy into electrical energy. The process occurs by detecting the pressure force that is exerted on the surface. This force is then converted into an electrical signal (current or voltage). The value of the electrical signal is relatively proportional to the pressure force.

Frequently Asked Questions / FAQ
The compensating strain gauge is used to measure the pressure force taking into account the influence of external factors, primarily air humidity, temperature and atmospheric pressure.
The correct operation of the strain gauge sensor can be checked by supplying it with the appropriate voltage at nominal load and reading the output voltage value with an electric meter .
The resistance strain gauge uses the phenomenon of changing electrical resistance when changing the dimensions of the resistance material . Such devices are used, for example, to measure stress or pressure, for example in loading systems.
