Thermocouples are instruments that are designed to provide temperature measurement of substances and have a variety of applications such as;
Medical - research into DNA and hypodermic insertion to detecting a tumour.

• Vehicle diagnostics - used to monitor and adjust factors such as battery health, exhaust readings, spark plug function and brake performance.


• Temperature readings in boilers, heating sensors, and ovens


• Food thermometers, industrial probes, and sensors

Screened share a lot in common with unscreened cables however screened cables emit less electromagnetic energy which can cause signal interference with cables that are nearby.
