FIELD: measuring equipment.
SUBSTANCE: invention relates to instrumentation. Technical result is achieved by the fact that in the of coating thickness measuring device, comprising a sensor in the form of a transformer with primary and secondary windings, connected via a primary winding to an alternating current source, and a recorder, a first amplifier, a light emission source, a photodiode and a second amplifier are forced into application, the secondary winding of the transformer through the first amplifier is connected to a light source, the photodiode is connected to the recorder through the second amplifier, the output of the latter is the output of the device.
EFFECT: technical result is higher accuracy of coating thickness measurements.
