The principle of operation of temperature sensors TSPT is based on the
change of electrical resistance of the temperature-sensitive element from the temperature.
Temperature sensors TSPT consist of one or
several structurally connected primary temperature transducers, protective
housing with or without mounting elements and switching devices in the form of terminal head, box, connector or connector.
terminal head, box, connector or cable.
The sensing element (SE) of the primary converter is made of a metal
wire of bifilar winding or film, applied on a dielectric substrate in the form of a meander.
meander. The PE has leads for attaching connecting wires and a known dependence of the
of electrical resistance to temperature.
For protection from mechanical influences, the CE is placed in a protective case.
