ABSTRACT:
The invention is directed to an uplift sensor for detecting uplift from a planar surface. The sensor comprises wedge-shaped bracket having an elongated member mounted therein which contacts the uplift and in response thereto depresses a hydraulic piston in a hydraulic cylinder thereby producing a hydraulic uplift signal. The sensor is provided with a spring operatively coupled between the elongated member and the mounting bracket for biasing the elongated member downwardly towards the uplift.
