System components D-R 220

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 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 optical surfaces of the measuring head and the reflector clean. A cable connects the measuring head to the supply box.

Optional:

Fail-safe shutters

The fail-safe 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 fail-safe shutter

A control electronics system is required for each fail-safe shutter.

Universal control and display unit D-ISC 100

The connected equipment is easy to configure and operate using the D-ISC 100 universal control and display 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 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
