DISPLACEMENT CONTROLLER Russian patent published in 2018 - IPC G01N27/90 

FIELD: measuring equipment.

SUBSTANCE: displacement controller comprises an eddy current sensor, the winding which is connected via the connecting cable to an output of a high-frequency generator, an input condenser and a high-pass filter whose output via a rectifier, a low-pass filter and an amplifier is connected to the indicator. According to the invention, a temperature measurement channel is introduced in the displacement controller, containing a DC power supply, an additional low-pass filter, an additional amplifier and an additional indicator, the output of the DC source is connected via the additional low-pass filter and connecting cable to the winding of the eddy current sensor, in addition, the output of the power supply is connected to the input of the additional amplifier whose output is connected to the additional indicator.

EFFECT: expansion of the functionality of the device by measuring the temperature in the working gap of the eddy current sensor.
