Shielded twisted pair cable is used for connecting to thermocouple inputs to reduce unwanted electrical noise.

Shielded Twisted Pair Cable

A type of cable in which the pairs of conductors are twisted together for the purposes of canceling out electromagnetic interference from external sources, with an additional shield to further protect against interference.

Thermocouple Inputs

Inputs that receive signals from thermocouples, which are temperature-measuring devices consisting of two dissimilar metals joined together, generating a voltage related to temperature.

Electrical Noise

Undesired noise overlaid on a meaningful signal, making its informational content difficult to discern.
