D-ISC 100

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 big display
  • Quick parametrization of the connected sensors
  • Maintenance and monitoring via safe intranet / internet remote access
  • Integrated power supply for one DURAG sensor
  • Efficient upgrading by internal expansion modules and converters


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

The universal display and operating unit D-ISC 100 can be connected to up to 8 DURAG sensors.
The big LC display simultaneously shows up to 4 measuring results.

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.

Suitable for all new generation DURAG Sensors
