Mechanical design
The sensor consists of sleeve (40.5 mm in length), sensing element and 2-core con-
necting cable. The sensing element is encapsulated in the sleeve so that it is mechani-
cally and electrically protected. The sleeve also ensures strain relief for the connecting
cable. The end of the cable carries ferrules for easy connection.
Different accessories are available for fixing the sensor.
Engineering notes
The permissible cable lengths are dependent on the type of controller with which the
sensor is used. They are specified in the Data Sheet of the relevant controller.
Mounting and installation notes
The connecting cable should always be connected to a conduit box.
When mounted in a protection pocket, the sensor must always be fixed in the pocket by
means of the cable holder.
Instructions for mounting in induction or fan coil units:
The sensor should be fitted in the location specified by the manufacturer of the terminal
unit. If there is no such specification, it must be fitted in the return air flow where it cap-
tures the temperature of the room air drawn in. It should be fitted as high as possible to
minimize the floor effect. The sensor must be protected against heat radiation from the
terminal unit.
