    摘要： A displacement detector has a contact sensor incorporating a differential transformer and a circuit for adjusting the amplitude of the driving signal for driving a differential transformer of the sensor by feeding back as a standard signal the driving signal through an amplifier and an AC-DC converter as a standard signal. The sensor has a housing containing a mobile member. The mobile member has a shaft with a hole. An outer tubular body of a linear bush and a ball guide each have a hole, and a pin is inserted through these holes movably in the direction of movement of the mobile member such that the rotation of the mobile member is prevented.

    摘要： A circuit for a displacement detector having a contact sensor with a sensor coil forming a differential transformer is disclosed. The circuit includes a driver for generating a driving signal for driving the sensor coil, a standard signal processor for processing the driving signal and outputting a standard signal, an output signal processor for processing signals outputted from the differential transformer, a differential amplifier for carrying out differential amplification of the standard signal and the output signal from the output signal processing means, and an amplitude adjustor for adjusting the amplitude of the driving signal for the sensor coil to a constant value by feeding back the standard signal to the driver.
