D‑R 808 system components

Measuring device

The transmitter and receiver optics are integrated together with the electronics in a compact unit in a rugged housing. The measuring probe made of stainless steel 1.4404 can be supplied in two lengths of approx. 400 and 800 mm (from mounting flange).

Supply unit D‑TB 200 with purge air supply

The supply unit of the dust concentration measuring instrument D‑R 808 is used to supply electricity and purge air and provides the connection for the transfer of the measured data. The purge air is used to keep the optical interfaces of the D‑R 808 clean. The device automatically reports any failure of the purging air.

Mounting flange 130/240/500 mm

The connection flange made of carbon steel or stainless steel 1.4571 should protrude approximately 30 mm into the channel.

Software D‑ESI 100

Parameterization software, visualization of the measured data and performance of maintenance functions.

The D‑ESI 100 can be parameterized, maintained and, when faults occur, analyzed via the USB port with the help of a PC and the associated software.

Optional

Universal control unit D‑ISC 100

The connected equipment is easy to configure and operate using the D‑ISC 100 control unit. The display provides an immediate overview of the current measured values and the status of the measuring instruments.

Measured value acquisition

In the simplest case the measured values and reference values are transferred to the plant's control system. The measured values and status signals that are output can also be fed into an emission calculator system for further processing. Either via discrete signals (4 to 20 mA and configurable relay contacts) or via Modbus according to VDI 4201‑3.

Weather protection covers

Weather protection covers are available to protect the measuring system for outdoor installation.
