ABSTRACT:
An assembly for measuring differential pressures includes a manifold valve and pressure transducer assembly including two pressure transducers. The manifold valve includes two pressure inlet ports and two pressure outlet ports that communicate through the manifold's isolation valves. An equalization valve connects the two pressure lines. Mating flanges on the manifold valve and pressure transducer assembly are bolted together to form a pressure tight seal between the manifold valve outlet ports and the pressure transducer assembly inlet ports. The pressure transducer assembly also includes a mounting plate for supporting the pressure transducers. The transducers generate an electrical signal corresponding to inlet pressure. Signals from pressure transducers and an optional thermistor for each are wired to an electrical connector mounted on the side of the assembly. The signals are electronically compared with an external signal processing circuit that outputs a representative signal of the differential pressure.
