Abstract
A pressure transducer, a microprocessor, and associated electronics are enclosed in a probe housing which may be attached to a liquid product line with the pressure transducer responsive to the pressure of the liquid in the liquid product line to provide an electrical signal representative of the pressure. The probe microprocessor contains a software program to detect leakage from a pressurized liquid product line in which the liquid is subject to a pressure increase caused by thermal contraction. The probe also has the capability to directly operate a product pump with a signal connection between the probe and the pump.
