SPH19S Monosilicon pressure sensor Product introduction Monosilicon pressure sensor SPH19S is the piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable monosilicon sensor die. Stainless steel 316L housing with diameter Ф19mm. 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 sealed silicon oil, to transform the pressure to electric signal.The sensor die doesn't contact the measuring medium directly, which forms to isolated structure, suitable for various liquid medium.
