Installation of the sensors
Device position
The SITRANS SL may be mounted in any direction.
When mounting the sensors the large springs of the alignment flanges must face
downwards.
Proceed as follows:
1.
Check that the flanges are installed properly.
2.
Mount the receiver and transmitter, both with gaskets on the flanges and cross-tighten
the bolts.
3.
Align the sensors as described in section Alignment of SITRANS SL (Page 57).
CAUTION
Do not install sensors that require purging before the purging media is accessible. Never
leave a purged sensor with the purging media switched off since the process windows
can be easily damaged.
Note
The stability of the sensor alignment depends on the stability of the construction to which
the customer’s flange is mounted. If the incinerator wall or smoke duct is subject to
movements due to, for instance, thermal changes the sensors will need repeated
realignment. This can be avoided by mounting the sensor pair on an external, more
stable base, such as a concrete or steel support.
