Measurement device, has inductive displacement sensor with coil connected to oscillator so core movement causes oscillator frequency change detected by evaluation electronics

摘要

The device has an inductive displacement sensor (1) with a core (3) movable relative to a coil (2) and evaluation electronics (4) that determines an output parameter from the variable coil inductance caused by core movement. The evaluation electronics contains an oscillator (5); the coil is connected to the oscillator so that movement of the core causes a change in the oscillator frequency and the electronics determines the change in frequency.
