Dust monitoringDURAG D-R 320 Dust Monitor
The new scattered light dust monitor to detect lowest to medium dust concentrations in dry flue and process gas.
The D-R 320 is based on the back-scattered light principle. Thereby the light of a red laser diode illuminates the dust particles in the measuring volume of the flue gas duct. The light scattered backward by these particles is detected and evaluated.
A unique feature of the D-R 320 is the automatic background light compensation with means of a patented optical system with dual detector. This allows for an easy and quick Installation without any adjustment. A light trap is not required.

Flame SensorsDURAG D-LL 7XX Fibre optic systems
The installation of fibre optic systems is recommended if it is not possible to place the flame monitor at an optimal position in order to guarantee best and permanent flame monitoring. A fibre optic system is also useful if the conditions of the environment are harsh to electronic devices.
The fibre optic systems D-LL 701 and D-LL 702 have to be used in combination with the flame sensor D-LE 701. Fibre optic systems D-LL 703 and D-LL 704 are suitable for devices of type D-LE 703, D-LX 710 and D-LX 721.
The fibre optic systems D-LL 703 and D-LL 704 can be installed directly in the hot zones of the burner. The radiation of the flame is transferred outside by a temperature resistant fibre glass bundle and directed to the flame monitor.
