Digital Displays • Series DA

Description:
The digital displays DA are used as indicators by using external sensors with 0-10 V or 4-20 mA output. If necessary it can be used for adjust the zero-point of the connected sensor. At many applications the sensor is installed at difficult accessible places. Therefore it is often difficult to adjust the zero-point direct at the sensor. The digital-displays makes it possible to add or subtract a correction voltage or current to the sensor signal.

The aluminium housing has a high mechanical stability and good EMC- properties. It is suitable for installation into a control switchboard. If the input signal passes the critical value 20 mA or 10 V a red LED on the front indicates the overload of the sensor. DA can be completed with several additional options: two switching outputs, RS232-interface 4-20 mA transmitter or frequency output 0-10 kHz.

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