‣
Install the sensor upstream from the pressure regulators.
‣
Leave enough room for the cable connector at the end of the lamp and at the end of the
detector housing. Unimpeded access to these areas is also required for connection/removal
tasks.
‣
The operation of sensors under pressure prevents the formation of air or gas bubbles.
NOTICE
Mounting errors
Possibility of sensor damage, twisted cables or similar
‣
Make sure that the sensor bodies are protected against damage from external forces - such
as trolleys on adjacent paths.
‣
Remove the cable before you screw the lamp or detector onto the flow assembly.
‣
Make sure to avoid exerting excessive tensile force on the cable (e.g. from jerky pulling
movements).
‣
Make sure to observe the national grounding regulations when using metal assemblies.
If the sensor is ordered together with the assembly OUA260, the flow assembly is ready-
mounted on the sensor upon delivery. The sensor is ready for use immediately.
If the sensor and assembly are ordered separately, you must mount the sensor as follows:
1. Install flow assembly OUA260 in the process via the process connections.
2. Make sure to fit the O-ring seals on the lamp and detector.
Screw the lamp and detector onto the flow assembly.
The lamp and detector can be installed in and removed from the assembly without this
affecting the process line.
5.3 Post-installation check
Put the sensor into operation only if you can answer "yes" to the following questions:
• Are the sensor and cable undamaged?
• Have you chosen a correct mounting angle?
