DS2805

Sensit HPS-A Series 4-20mA Output
Pressure Transmitter
Two wire, 4-20mA output transmitters offering
superb chemical and corrosion 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.
