Retort Thermocouple Installation
Probe thermocouples enable operators to record more accurate temperature readings
inside a heated vessel (work tube, retort, reactor etc.).
The thermocouples enter the retort through compression glands, and plug into the
corresponding sockets on the rear of the furnace case.
Thermocouples may also be plugged into an independent external temperature reader.
To install the retort thermocouples:
Note:
Ensure that there is
sufficient space at the rear of the
furnace to allow for the easy
insertion and withdrawal of
thermocouples.
l
Gently twist the compression nut
on the thermocouple gland to
loosen the seal and allow for ther-
mocouple access.
l
Carefully insert the probe ther-
mocouple through the gland.
l
Securely tighten the gland to
ensure that the thermocouple
remains in position and that any
atmosphere contained inside the
retort does not escape.
l
Connect the male end of the ther-
mocouple lead to the relevant
socket at the rear of the furnace
body. The socket(s) are labelled.
