MODEL SA • PRESSURE TRANSDUCER The SA pressure transducer has a water resistant, stainless steel case for APPLICATIONS • FREON AND AMMONIA REFRIGERATION SYSTEMS • HYDRAULIC CONTROLS • AGRICULTURAL SPRAYERS AND DUSTERS • COMPRESSORS • ENGINE CONTROLS • ENERGY MANAGEMENT SYSTEMS • ROBOTICS • AUTOMATED MACHINING • PNEUMATIC SYSTEMS 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). 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 1-6V from an unregulated supply. It is fully calibrated and compensated prior to shipment, and is field interchangeable.
