The Validyne Model P79 is a differential pressure transducer designed for rugged measurement applications. The variable reluctance sensing technology allows the P79 to be used in a wide variety of low pressure measurements where fast dynamic response, high resistance to the vibration and superior signal stability through ambient temperature change is required. The P79 will accept both gases and liquids directly at the sensing diaphragm; there are no internal isolation fluids to slow the sensor response or cause excessive temperature shift errors. The P79 is available in two analog output configurations: 4-20 mA current sink output and DC output. The 4-20 mA output version is a true two-wire system which will operate over a supple voltage of 9 to 55 VDC. The DC version is a direct replacement for the VDC signal. Sensor wetted parts include 410 steel, suitable for inert gases and hydrocarbons, 316 SST for water-based fluids and Inconel for corrosive applications.
