Features

SS121E24 series piezoresistive miniature pressure transducer is developed for measuring hostile media in harsh environments. The transducer is fully compatible with 316L stainless steel. The transducer is calibrated and temperature-compensated. It is available for use with either a constant voltage or current source. It offers multiple pressure connections for easy integration into OEM equipment.
SS121E24 series is a rugged and reliable transducer with a stainless steel structure featuring no O-rings for sealing. It covers a pressure range from vacuum to 200 bar. We recommend the transducer for various pressure-sensing applications involving corrosive liquids or gases.
