Products > Pressure > Sensit HPS Pressure Transducer

HPS - A 4-20mA OUTPUT Two-wire, 4-20mA output transducer offering superb chemical and orrosion resistance. Gauge or Absolute pressure is detected using a four active arm strain gauge bridge sensor, fused to a high-purity ceramic diaphragm. Available in three classes of accuracy and compensation specified below, with ranges from 100mbar to 600 bar or scaled to customer requirements.
