25 www.bdsensors.com DMP 331Pi Precision Pressure Transmitter pressure ports and process connections with flush welded stainless steel diaphragm accuracy according to IEC 60770: 0,1 % FSO Nominal pressure from 0 ... 400 mbar up to 0 ... 40 bar Output signals 2-wire: 4 ... 20 mA 3-wire: 0 … 10 V others on request Product characteristics ► excellent temperature response 0.04 % FSO / 10K ► processing of the sensor signal using digital electronics ► process connections suitable for hygienic application ► vacuum resistant Optional versions ► IS-version Ex ia = intrinsically safe for gases and dusts ► communication interface for adjustment of offset, span and damping The precision pressure transmitter DMP 331Pi demonstrates the further development of well- tried industrial pressure transmitter DMP 331P. 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. The temperature range of -40 ... 125 °C can be extended by the integration of a cooling element up to 300 °C. Preferred areas of use are Laboratory techniques Food and beverage Pharmaceutical industry PRECISION PRESSURE TRANSMITTER
