The hermetically sealed sensor cable contains small hybrid circuits which, depending on the application, are placed at selectable intervals. The hybrids, which contain an integrated circuit with a defined address and a semiconductor temperature sensor, are electrically connected by a flat flexible cable.
The flat flexible cable and temperature measuring points, 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 in a -40°C to +85°C (for short periods +200°C) range, with a resolution of 0,1°. On account of its 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, a functional check is always given. Self locking clamps are usually used to mount the cable. The relative stiffness of the cable allows a spacing of one meter between clamps. Damage 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.
