DMP 331Pi Precision Pressure Transmitter Pressure Ports and Process Connections with Flush Welded Stainless Steel Diaphragm accuracy according to IEC 60770: 0.1 % FSO The precision pressure transmitter DMP 331Pi demonstrates the further development of welltried industrial pressure transmitter DMP 331P. Nominal pressure from 0 ... 400 mbar up to 0 ... 40 bar The signal from the specially designed piezoresistive stainless steel sensor is processed by the newly developed digital electronic system, performing thus an active compensation of sensor-specific deviations such as hysteresis, thermal errors and non-linearity. Output signals 2-wire: 4 ... 20 mA 3-wire: 0 … 10 V others on request The temperature range of -40 ... 125 °C can be extended by the integration of a cooling element up to 300 °C. excellent temperature response 0.04 % FSO / 10K processing of the sensor signal using digital electronics process connections suitable for hygienic application Laboratory techniques vacuum resistant Pharmaceutical industry IS-version cooling element for media temperatures up to 300 °C BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
