Apparatus and method for sensing diaphragm failures in reciprocating pumps.

摘要

Apparatus for monitoring the diaphragm integrity in a diaphragm pump. A single continuous circuit trace (29) is supported on a pump diaphragm (12). An electrical circuit is connected to the continuous circuit trace (29) for measuring both the continuity and a potential ground fault condition between the circuit trace and pumping liquid. The circuit trace is formed in a configuration which resists the effects of strain induced by continuous flexing of the diaphragm (12).
