Pressure Transmitter PCI280 Introduction The PCI280 series pressure transmitter are designed to measure gauge pressure, vacuum pressure and absolute pressure of gases, vapours and liquids. It’s stainless steel housing is ideal for industrial environments. Special circuits are built in to allow adjustment of zero and span. Application and construction The PCI280 pressure transmitter is applicable to the measurement of the pressure, underpressure and absolute pressure of gases, vapours and liquids. The active sensing element is a piezoresistant silicon sensor separated from the medium by a diaphragm. The electronics is placed in a casing with a degree of protection from IP65 to IP68, depending on the type of electrical connection applied.
