SEC 15 d-LIST Sensor Cable

The hermetically sealed sensor cable contains temperature sensors which, depending on the application, are placed at selectable intervals. The sensors are electrically connected by a flat flexible cable. The flat flexible cable and temperature sensors are surrounded by a filling material, which in turn is covered by an aluminium shield protecting against EMI. A flame retarding, halogen free cable sheath completes the sealed structure of the sensor cable. The cable can measure temperatures from -40°C to +85°C (for short periods +120°C) with a resolution of 0,1° Celsius. On account of it's maintenance- and adjustment-free operation, the sensor cable can be used in areas which are not or only partly accessible during normal operation. Due to the constant interrogation of the temperature sensors by the control unit SCU 800, a functional check of all temperature sensors is always given. As a rule, self-locking clamps are used to mount the cable. The relative stiffness of the cable allows a spacing of one meter between clamps. Damaged cable sections can easily be repaired by cutting out the damaged section and connecting a new piece in it's place with the aid of sleeve joints
