D-ISC 100 xx2

Universal operating unit

Universal display and operating unit in stainless steel field housing for connecting all new generation DURAG measuring systems. Ease your installation by combining several emission and flow measuring devices with only one operating unit. Realize redundant system setups with the D-ISC 100 easily and efficiently.


  • Automatic sensor detection allows easy installation and setup
  • Convenient operation by keypad and large display
  • Quick operation, parametrisation and data transfer of the connected DURAG sensors
  • Integrated power supply for one DURAG sensor
  • Modular setup, expandable with expansion modules 
  • Combination of two D-ISC per DURAG sensor for local and remote operation (daisy chain)
  • Different versions available tailored for different customer needs: compact, medium, integrated purge air blower or 19'' rack version


Suitable for all new DURAG Sensor generation for dust and volume flow measurement systems, display and operating unit for several DURAG sensors.

e.g. D-FL 100, D-FL 220, D-FL 220T, D-R 220, D-R 220T, D-R 290 2G, D-R 320, D-R 808

The universal display and operating unit D-ISC 100 can be connected to up to 8 DURAG sensors.
The large LC display simultaneously shows up to 4 measuring results.
The D-ISC 100 can either be installed close to the sensor at the stack (local) or on the control room (remote). From now on, it is possible to combine two D-ISC 100 units per DURAG sensor.

Direct access to all measuring values and parameters of the connected sensors.

The D-ISC 100 allows parameterization and maintenance of all connected sensors via the integrated keypad or a connected PC.
The D-ISC 100 also supports remote access via intranet or internet connection.
