D-TB x00

Supply unit

Supply unit for power supply of all new generation DURAG measuring systems for installation at stack level. Ease your installation by combining power and purge air supply in only one unit.


  • Power supply unit for one DURAG measurement system
  • Version with integrated purge air blower available
  • Different housings for different environmental conditions available
  • Combination with D-ISC 100 possible
  • Allows data transmission from DURAG measuring system to environmental data management system




Suitable for all new DURAG dust and volume flow measurement systems, also with integrated purge air supply available.

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

The supply unit D-TB x00 provides power supply for one DURAG measurement system.
For several measurement systems a version with integrated purge air supply is available (e.g. D-R 220, D-R 320, D-R 808).

Connectible to DURAG universal display and operating unit

The D-TB x00 can be connected to a  Opens internal link in new windowD-ISC 100 for setting up a network of sensors which allows parameterization and maintenance of all connected sensors via the integrated keypad or a connected PC.
