Fixed Digital differential pressure transmitter


The pressure transmitters of the series DMU measures overpressure, vacuum, difference- and
absolute pressure and velocity of flow in air and non aggressive gases. The measuring values are directed to a 0-10 V analog output (DMU4) or a 4-20 mA output (DMU2).They are shown on a 3,5- digit LED-Display with at figure height of 12,7 mm. The DMU2 has a 4-20 mA- 2-wire output, that means its no external power supply required. Because of used piezoresistive cells the pressure transmitter reaches high reliability and precision. The enclosure has protection class IP65. It is suitable for wall- mounting installation. The user is warned against overload pressure by a red LED on the front. The pressure transmitter DMU 4 can be completed by several additional options:
Switching output with display switching level and LED on the front
Delay of analog output and delay of switching output of 60 seconds possible
Power supply 24 VDC, 24 VAC or 230 VAC
Square root output for measuring velocity of flow
