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.

Order Note:
1. We suggest you to use Floating construction when you install the sensor to prevent affecting sensor stability;
2. Please pay attention to protect sensor isolated diaphragm and ceramic compensated board, to avoid damaging sensor and affecting the performance;
3. When the temperature exceeds viton working temperature, or the user needs to use sensor at rugged environment, please contact our company freely.
