Installation Of The T Probe - Pfaudler TW Series Operating Instructions Manual

Temperature probes type T/TW
5.5 Installation of the probe
carriers
5.5.1 Installation of tubular probe
The term tubular probe is used for the
following probe carriers in this context:
Baffles
n
Thermometer well
n
Quatro-Pipe
n
C baffles

Before installing a tubular probe in a
reactor or a pipeline, you should verify
whether there is sufficient distance to
the agitator and the reactor wall. If nec-
essary, suitable spacers or reducing
flanges must be used.
Assembly process:
Place flange gasket on nozzle.
t
Protect the nozzle and the probe
t
against damage by inserting a piece
of cloth or a PTFE sleeve into the noz-
zle. Slowly introduce the tubular probe
into the reactor through the nozzle.
Avoid pendulum motion.
Tighten flange screws evenly cross-
t
wise with the prescribed tightening
torque; (cf. Tab. 3).

When using your own reduc-
ing flanges, please make sure that
the element covering the contact
area below the terminal box does
not sit on the reducing flange (cf.
Fig. 2). In the event of non-compli-
ance, the glass may be damaged at
the bottom side of the flange, and
the fused-in metal strips may be
interrupted.
5.5.2 Installation of ring probe
The ring probe may generally be installed
in any position inside the pipeline. How-
ever, it must be noted that the T probe
does not work unless the measuring loca-
tion is sufficiently covered with product. In
radial direction, the measuring location is
in the same place as the terminal box.
The ring probe is be installed in the pipe-
line between 2 flanges using gaskets.
Tighten flange screws evenly crosswise
with the prescribed tightening torque;
(cf. Tab. 3).
Max. tightening torques in Nm with admis-
sible operating pressures of:
–1 to +10 bar –1 to +16 bar
