D-R 220 system components

Measuring head

The transmitter and receiver optics are integrated together with the electronics in a sturdy, compact polyamide housing. The measuring head is mounted on the weld-in flange.

Reflector

The reflector is installed in a sturdy polyamide housing. The reflector is mounted on the weld-in flange directly opposite the measuring head.

Supply unit D‑TB 200 including purge air

A hose connects the measuring head and the reflector with the supply box. The filtered air is used to keep the scattered light interfaces of the measuring head and the reflector clean. A cable connects the measuring head to the supply box.

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.

Additional options

• Neutral density filters for linearity check
• Sighting scope for easy alignment
