Product Overview:
HPM280 Protective Pressure Transmitter adopts high stable and reliable diffused silicon piezoresistive pressure sensor as signal measuring element. It is processed through automatic testing and laser trimming to achieve wide temperature compensation. The product has stable and reliable performance because they all pass the strict testing and ageing testing. With field digital display, it is applied to the occasion of measuring pressure in the hostile working environment. HPM280 can be widely used for pressure measurement in the fields of machinery, metallurgy, petrochemical, power, etc.
