Features
SS306 series analog pressure sensor is designed by piezoresistive sensing technology. The pressure sensor cell is laser welded with a process connection. A complete welding structure without an O-ring prevents leaks. It also makes the sensor tough against mechanical shock and vibration. This compact pressure sensor is strong and stable for long-term use. It works well for critical industrial applications and tough media. It includes high-temperature steam, ammonia, acetone, freon, and other refrigerants. Various electrical connections and pressure ports simplify the adaptation to different applications. The attractive price level of the sensor makes it ideal for OEM applications.
