A monitoring device is described which is particularly useful in tracking the axial displacement of a rotating shaft in either axial direction. The monitoring device includes a position monitoring function, an alarm and trip function, and a test function. Various fluidic devices are combined into a fluidic circuit for carrying out the foregoing functions in an improved, reliable and less costly manner than heretofore available in prior art devices. A distinct advantage of the invention is its relative ease of installation in retrofit applications.
