<p>A diaphragm failure monitoring system for detecting leakage in a diaphragm of a diaphragm pump. The system includes a pump (10) having an operating chamber (16) containing a working fluid (30) and a pumping chamber (14) for pumping material into and out of the pump and a diaphragm (18) separating the operating and pumping chambers. A first optic fiber (52) is joined to the operating chamber for transmitting an optic signal across the working fluid. A second optic fiber (60) is joined to the operating chamber for receiving the optic signal from the first optic fiber. An electric signal establishing device (56) establishes a fist electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through uncontaminated working fluid. The electrical signal establishing device establishes a second electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through contaminated working fluid, whereby leakage of a contaminating material through the diaphragm into the operating chamber can be detected when the second electrical signal is established.</p> |
