Abstract
Pressurized operating fluid, such as oil for hydrostatic fluid bearings, is directed into a chamber against a plunger urging the plunger into a first position. A monitoring pressure force slightly less than the force of the operating fluid when the operating fluid is at a minimum working pressure is exerted against the plunger tending to move the plunger from this first to a second position. Thus, when the pressure of the operating fluid drops below the minimum working pressure, the plunger is moved to its second position and such movement is sensed, thereby sensing the malfunction.
