ABSTRACT:
A single differential area piston with annunciator flag and coacting malfunction indicia scale is capable of monitoring a relatively large number of malfunction or shut-down points on a compressor or the like. The annunciator piston responds to leakage of an operating fluid medium caused by venting to atmosphere of a particular malfunction sensor on a compressor or like machine with which the annunciator is connected. The annunciator or indicator additionally operates shut-down and start-up control instrumentalities for the monitored machine. A great simplification in tubing, tubing connections and venting means is obtained in comparison to the prior art.
