- Low power consumption
- Speed up to 10 m / s
- Wide range of measuring ranges
Linear potentiometric transducers are analog sensors for measuring linear displacement in an absolute way.
These devices work on the principle of a variable linear resistor, i.e. the slider is moved along the resistive wire. If the voltage is connected to the transducer, the voltage at the output of the slider is directly proportional to the position of the slider on the resistive bar.
The resistive path is most often made of conductive, high-quality material. Due to this, not only a large resolution is achieved, but also measurements can be made with a higher displacement speed (up to 10 m / s).
The most important advantages of measuring with potentiometers is the absolute measurement method, i.e. after switching on the measuring device, the read position is an absolute position. Others include the ease of signal processing and low power consumption, since a voltage source is sufficient. Another is possible measurement in ranges between 8 and 2000 mm
