SPM 402 Series

Send Me Product Information Datasheet Download

The SPM 402 Series offers piezoresistive silicon, stainless steel pressure sensors. Media isolated sensors are designed to operate in hostile environments, yet provide the outstanding sensitivity, linearity, and hysteresis of a silicon sensor. This pressure sensor is compatible with 316L stainless steel, a type of steel that increases corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at high temperatures.

 

The piezoresistive sensor chip is housed in a fluid-filled cylindrical cavity and isolated from measured media by a stainless steel diaphragm and body. The oil-filled cavity in this unique pressure sensor design is at a minimum volume so the accuracy is greatly improved. The SPM 402 silicon pressure sensor is a thermally compensated device and has a millivolt output of up to 210mV at a 1mA supply current (or supply voltage 10V). This new pressure sensor offers design engineers excellent performance in various applications, especially for mid to high pressure and smaller solutions.
