ABSTRACT:
A utility pipe displacement sensor comprises a protective housing and an indicator stick disposed in a vertical position within the housing. The indicator stick is capable of displacement within the housing and is maintained in its vertical position within the housing by the use of centralizing discs or nails. The sensor is arranged in such a manner that the lower ends of both the housing and the indicator stick are in communication with the outer surface of a buried utility pipe. Due to this arrangement, any displacement of the utility pipe is translated into a visually perceptible displacement of the indicator stick within the housing. Thus, any displacement of the utility pipe can be determined by determining the position of the indicator stick with respect to the housing.
