5.2.2 Assembling the Head Mounting Components (Tx/Rx)
The STACK 602 is supplied with two stack mounting stubs (
Figure 9
). The stack
mounting stubs must be welded onto the stack in the chosen position. Then the
sensor body (incl. alignment aid and air purge with diffuser connector) is bolted on.
Figure 9: Installing anti-fouling fittings.
The flanged sensor body and stack mounting stubs are supplied with all fixings
and the required hardware pre-assembled in the correct orientation. An optional
anti-fouling fitting is available for installation between the sensor and the flanged
stack mounting stub (see
Figure 9
above). For high-temperature applications, an
additional high-temperature standoff should be fitted between the mounting stub
and the alignment aid/sensor flange (see
Figure 8
on page
26
).
The enclosure is then inserted into the body and attached using four grub screws
(
Figure 10
). Note that once installed, the Receiver head requires aligning, which
may include removal of the sensor enclosure (see
Appendix
A on page
57
).
