All Sensors of Morgan Hill, California has announced a brand new offering of stainless steel, media isolated pressure sensors. The second line released is the SPA 401 Series. This new amplified pressure sensor offers design engineers excellent performance in various applications, especially for low pressure and smaller solutions.
Media isolated sensors are designed to operate in hostile environments and yet give 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 SPA 401 silicon pressure sensor is a fully compensated device and has an amplified ratiometric output. Devices are available in 1.5, 3, 5, 15, 30, 50, and 100 PSI.
