Temperature sensors KTNN Ex

The principle of operation of temperature sensors KTNN Ex is based on the thermoelectric effect - generation of thermoelectromotive force proportional to the temperature difference between the working end and the free ends of the two conductors. end and free ends of two conductors (thermoelectrodes) made of different metals or alloys. alloys.

Temperature sensors KTNN Ex consist of one or several structurally connected primary temperature transducers, protective housing with or without mounting elements and switching devices in the switching centre. without them and switching devices in the form of a terminal head, box, connector or extension wires. The primary transducer of temperature sensors KTNN Ex is made in the form of cable or wire sensing element (SE).

The cable PE is a flexible metal tube with one or several pairs of wires placed inside it. inside it one or more pairs.
