INFRARED TEMPERATURE CONTROLLER
This is a non contacting system to check fluid coupling
temperature. It is reliable and easy-mounting.
It has 2 adjustable thresholds with a logical alarm on the former,
and a relay alarm on the latter.
The proximity sensor must be positioned near the fluid coupling
outer impeller or cover, according to one of the layouts shown in
Fig. 9.
It is adviced to place it in A or C positions, as the air flow
generated by the fluid coupling during rotation helps to remove
possible dirt particles that may lay on the sensor lens.
The distance between the sensor and the fluid coupling must be
about 15-20 mm (cooling fins do not disturb the correct operation
of the same sensor).
To avoid the bright surface of the fluid coupling reflecting light and
producing an incorrect temperature reading, it is necessary to
paint the surface which is directly facing the sensor a flat black
colour (a stripe of 6-7 cm is sufficient).
The sensor cable has a standard length of 90 cm. In the case
where, a longer cable is required, use one that is plaited and
shielded as per type “K” thermocouples.
