System components D-R 220

Measuring head

The transmitter and receiver optics are integrated together with the electronics in a sturdy but 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 box with purge air unit

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

Optional:

Quick-closing shutters

The quick-closing shutters are mounted on the measuring head and the reflector side between the weld-in flanges and the connected devices (measuring head, reflector). In the event of a fault (failure of the power supply or purge air) they automatically close the path between the exhaust gas duct and the measuring equipment.

Electronics for quick-closing shutter

A control electronics is required for each quick-closing shutter.

Universal control unit D-ISC 100

The connected equipment can be operated and configured conveniently using the D-ISC 100. 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 a recorder is used to record the measured values and the reference values. The measured values and status signals that are output can also be fed into systems that will process these further.

Weather protection covers

Weather protection covers are available to protect the measuring head and the reflector when the measuring system is installed outdoors.

Additional options:

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