LVDT series: Displacement sensors with external electronics
Measurement ranges ±1 … ±25 mm Extremely accurate also under difficult ambient conditions Long-term stability Wear-free Easy installation
Displacement Sensors have a plunger which moves freely in the sensor housing. The plunger is joined to the object by a thread to transfer the movement of the measurement object. The measurement process in the sensor takes place without contact and is therefore wear-free. The displacement sensors are mainly used to measure and monitor movements, displacements, positions, strokes, deflections, dislocations, etc. in vehicles, Machines and systems.
The high sensor resolution is limited only by the noise in the sensor electronics. A further advantage of the symmetrically constructed sensors in the LVDT series is the zeropoint stability of the systems. The sensors are supplied with an excitation frequency of 1 to 5 kHz depending on the measurement range and an excitation amplitude of 2.5 to 5 Vrms. Matched sensor electronics are available in this respect.
With appropriate setting possibilities for the excitation frequency and amplitude, the sensors can also be operated with alternative electronics.
