Compound Pressure Transducers

In a compound pressure transducer, the sensor is zero referenced to atmospheric pressure. The transducer has an offset “zero” output signal such that the baseline signal measures a full vacuum pressure range of -14.7 PSI (or -1 bar). Typically this is offered for low pressure, gauge referenced transducers.

Bi-Directional Pressure Transducers for Vapor Recovery

Core Sensors offers a variety of high quality bi-directional pressure transducers for use in low pressure vapor recovery operations. Unlike a unidirectional pressure transducer that can measure pressures from zero to a defined positive pressure (i.e. 0 to 70mBar), bi-directional pressure transducers measure both positive and negative pressure (i.e. -70mBar to +70mBar).
