A Sensing System

Abstract

There is provided a system (2) for detecting relative motion between a first member (60) and second member (62) (illustrated as a locking bar (22) comprises a first sensor unit (4) and a second sensor unit (6). The first sensor (4) comprises a first accelerometer (8) and the second sensor (6) comprises a second accelerometer (10). The first and second sensors (4) and (6) each independently communicate with a processing and recording unit (12). The processing and recording unit (12) is configured for processing signals from the sensors (4) and (6) and determining changes in the relative displacement of one sensor to the other. The unit (12) is also able to record changes in the relative displacement and log, using global positioning technology, the locations at which the change occurred.
