Introduction
SPT81 high stable OEM sensor is the piezoresistive pressure sensor
with isolated construction and precise compensation. It uses high
stable silicon 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
media, to transform the pressure to electric signal.
SPT81 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.
