Use cable ties made of metal for temperatures above 95 C Ordering and delivery When ordering, please give type reference of sensor and part numbers / type reference of the accessories required. Example: Cable temperature sensor QAP2010.150. The cable temperature sensor is supplied without any mounting accessories. These must be ordered separately. Equipment combinations The cable temperature sensors are suited for use with all types of controllers that can handle the sensor s passive output signal. Function The sensor acquires the temperature via its sensing element. The resistance of the sensing element changes as a function of the ambient temperature. The resistance value is used for further handling by a suitable controller.

Mechanical design The sensor consists of sleeve (40.5 mm in length), sensing element and 2-core connecting cable. The sensing element is encapsulated in the sleeve so that it is mechanically 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 Mounting and installation 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. 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 captures 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. Disposal The devices are considered electronics devices for disposal in terms of European Directive 2012/19/EU and may not be disposed of as domestic waste. Dispose of the device via the channels provided for this purpose. Comply with all local and currently applicable laws and regulations. 4/6
