  • Apparatus and method for sensing diaphragm failures in reciprocating pumps
    Patent number: 4781535
    Abstract: Apparatus for monitoring the diaphragm integrity in a diaphragm pump. A single continuous circuit trace is supported on a pump diaphragm. An electrical circuit is connected to the continuous circuit trace 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.
