Piezoresistive pressure sensors for absolute, gauge and differential pressure

PT124G-3100 high stable OEM sensor is The piezoresistive pressure sensor designed with isolated construction and precise compensation. It uses high stable silicon die. Stainless steel 316L housing with diameter Ф19mm.
Widely 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.
PT124G-3100 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.
