absolutevoltage outputDC

Features • Gauge, absolute, sealed gauge • Constant current power supply • Isolated construction, enable to measure various media • 019mm standard OEM pressure sensor • Full stainless steel 316L • Wider temperature compensation -1 OOC +800C • Long-term stability 0.1 %FS/year Application • Industrial process control • Level measurement • Gas, liquid pressure measurement • Pressure checking meter • Pressure calibrator • Liquid pressure system and switch • Cooling equipment and air conditioning system • Aviation and navigation inspection SPT81 high stable OEM sensor is the piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable silicon die. Stainless steel 316L housing with diameter @19mm. Wider temperature compensation and zero correction are calibrated by laser trimming technics. The measured pressure is transmitted onto silicon die through 316L diaphragm and inner media, to transform the pressure to electric signal. SPT81 piezoresistive pressure sensor is inspected and screened on automatic production line, testing and checking time after time strictly. It is widely used for various pressure measurement fields.
