Pressure Transmitters with Display • Series DMU2/DMU4

Description:
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 or 0-10 kHz 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
 - Frequency output 0-10 kHz

Measurement ranges:
  0-0,25 mbar (0-25 Pa) in steps up to 0-10 bar (0-1000 kPa)

Medium:
  air and non aggresive gases

Applications:
  control of airblowers
  supervsion of airfilters
  level monitoring of liquids
  monitoring of air flows
  pressure control and regulation in cleanrooms
  medical engineering
