NOTICE

Damage to the optics

Always mount the purge device first before installing the sensors to prevent the optical

components from being damaged during the rest of the mounting process. Use sensors

equipped for this particular purge procedure for optimum results. These are available from

Siemens.

NOTICE

Damage due to overpressure during sensor-side purge

If the sensor purge lines are connected to the process purge lines, check valves may need to be

used to ensure that process gas cannot enter the purge line if a purge gas supply fails. This

especially applies to cascaded process and sensor purging, where otherwise there is a risk that

corrosive process gases may enter the sensor housing, for example.

Damage to the optics

The high-pressure glass in the sensors must not be exposed to any mechanical influence that

could lead to scratches or cracks.

• Use only a soft cloth to clean the glass.

• Before cleaning, make sure that the sensor can be dismantled without impairing safety.
