LG190H Pressure sensor

Brief introduction

LG190H is the piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable silicon die, housing with outer diameter 19mm 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.
