  • Page 8: Functional Principle, Technical Data

    Functional Principle, Technical Data Functional Principle The MSC7401 is a single-channel miniature sensor controller for the operation of LVDT inductive displace- ment sensors (full bridge) and for half-bridge sensors. An electronic oscillator excites the primary coil with an alternating current of a constant frequency. The fre- quency and amplitude can be set for best operation mode of the respective sensors, see Chap.

  • Page 9: Design

    MICRO-EPSILON recommends the inductive displacement sensors and gauging sensors of the induSENSOR DTA and LDR series because they are optimally adjusted with the controller.
