Features
SS120 series piezoresistive differential pressure transducer works following the principle of piezoresistive effect. It uses a high-sensitivity piezoresistive silicon chip for pressure sensing. All metal parts are in contact with the pressure media from stainless steel 316L. The piezoresistive differential pressure sensor is highly stable and reliable. It also features high static pressure capability. It is widely used to measure liquid and gas differential pressure.
