Attachment of the sensor for the remote control
The sensor for the control of the feed line temperature for an outside tempe-
rature guided control can be mounted either on the upper part of the housing
that has a hole for a round sensor, or at the feed line of the heating loop, or
in the upper part of the tubular shell of the Electric heater-circulator.
If the sensor is attached to the feed line or to the manifold, one has to take
care that the sensor is in intimate contact with the feed line with the help of
heat conducting paste (in no case should the sensor be attached to a plastic
part). If the sensor is attached to the manifold of the feed line, the sensor has
to be placed before the first loop.
If the sensor is attached to the tubular shell one has to take care that the
total surface of the sensor facing the shell is in direct contact and that the
sensor is attached to the upper section of the shell!
Sensor mounting in the
immersion shell:
The sensor will be inserted
into the hole at the upper
part of the Electric heater-
circulator with heat transfer
paste.
Sensor mounting at the
tubular shell:
The sensor has to be at-
tached as high as possible
on the tubular shell. Attenti-
on must be paid to insuring
good heat transfer contact.
Sensor mounting at the
feed pipe:
The sensor has to be at-
tached before the outlet
of the first loop and has to
have contact to metal.
The sensor for the control can be mounted according to the
possibilities shown here.
