Introduction:
LG190H High stable sensor is the piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable silicon die, housing with outer diameter Ø19mm 316L stainless steel housing. Wider temperature compensation and zero correction are calibrated by laser trimming technics. The measured pressure is transmitting onto silicon die through 316L diaphragm and inner media, to transform the pressure to electric signal.
