  • Electrical inclination sensor and a monitoring circuit for the sensor
    Patent number: 4937518
    Abstract: The sensor comprises a body defining a closed chamber which is partially filled with electrically conductive liquid. A main electrode and first and second auxiliary electrodes extend within the chamber in such a way that a variation in the inclination of the body from a predetermined position causes a corresponding variation in the electrical resistance between each auxiliary electrode and the main electrode. The monitoring circuit for the sensor comprises a generator which applies square-wave signals to the auxiliary electrodes in counterphase, and a detector/amplifier which is synchronized with the generator and samples the signal taken from the main electrode in the sensor.
