Abstract
A sensing device. The sensing device comprises a body containing a arcuate tube. A first conductor in the tube is able to move along the tube. There is a plurality of spaced contacts within the tube and conductors extending from the spaced contacts. There is a remote read-out to receive the information from the conductors to indicate the position of the first conductor in the tube and thus the inclination of the tube.
Claims10
A sensing device comprising:
- a body containing an arcuate tube;
- a first conductor in the tube able to move along the tube;
- a plurality of spaced contacts within the tube, said contacts comprising electrically conducting strips of material mounted on a non-conducting base, said base being adhered to the arcuate tube, neighbouring conducting strips being spaced apart by an area of said non-conducting base;
- conductors extending from said conducting strips;
- a remote read-out to receive information from said conducting strips to indicate the position of the first conductor in the tube and thus the inclination of the tube.

A sensing device comprising:
- a body containing an arcuate tube;
- a first conductor in the tube able to move along the tube;
- a plurality of spaced contacts within the tube, said contacts being probes extending through said tube;
- conductors extending from said spaced contacts, said conductors extending from the probes to a radio transmitter able to send a first signal indicating the position of the first conductor in the tube;
- a remote read-out to receive information from said conductors to indicate the position of the first conductor in the tube and thus the inclination of the tube, said remote read-out being a received able to generate a second signal upon receipt of said first signal, the second signal indicating the angle of the tube.
