ABSTRACT:
A system for measuring the gap between two surfaces is disclosed. The sensing apparatus comprises an actuator, an active sensor and a display. The actuator actuates operation of the sensing apparatus. The active sensor includes a transmitter for transmitting a wave signal beam reflectable off one of the surfaces and a receiver for receiving the reflected wave signal beam by the sensing apparatus. A signal processor is in electrical communication with the actuator, the transmitter and the receiver, for processing the reflected wave signal beam to determine the gap between the two surfaces. The display is in electrical communication with the signal processor for displaying the amount of gap between the two surfaces.
