The SA pressure transducer has a water-resistant, stainless steel case for complete protection from harsh environments. Internal hermetic sealing is used to provide measurement of absolute pressures (PSIA) or pressures referenced to a sealed chamber (PSIS). Gage pressure ranges are also available from 15 psig through 50 psig.<br>Underwriters Laboratories has approved the SA as a component in float and pressure-operated motor controllers (File #E93356). The SA produces a high-level voltage output of 1 Vdc to 6 Vdc from an unregulated supply. It is fully calibrated and compensated prior to shipment, and is field interchangeable. .. see full description
