Abstract:
An inclination sensor for use with an AC exciting voltage source which may have an asymmetrical waveform, comprising:a. a low-porosity ceramic body defining a closed chamber which is partially filled with a quantity of electrically-conductive liquid, said body having at least one flat wall;b. an arcuate resistive element disposed on said wall, said element having electrodes at each end thereof and an electrode at its midpoint, said midpiont electrode and a portion of said resistive element being immersed in said fluid; said end electrodes being adapted for connection to said AC exciting voltage source; andc. a discharge resistor connected between said end electrodes, said discharge resistor having a resistance lower than the resistance of said arcuate element to prevent polarization of said element by said electrolyte, whereby the variation in resistance observable between said third electrode and one of said end electrodes varies linearly with the angle through which said ceramic body is rotated.
