Process Engineering Division – Instrumentation and Automation Section – Daily Topics – Topic No. 2021-02-03: Discussion question: 377. Is it necessary to shield the compensation wire when using thermocouples for temperature measurement? What is the reason?
The compensation wire used when measuring temperature with a thermocouple does not require shielding. Because the potential is not disturbed.
The compensation wire used when measuring temperature with a thermocouple does not require shielding. Because the potential is not disturbed.
The compensation wire used when measuring temperature with a thermocouple does not require shielding. Because the potential is not disturbed.
Some studies show that shielded compensation wires can be used, but they must be connected properly; otherwise, they are likely to introduce interference.
No shielding is required; the generation of thermoelectric potential is related to the temperature difference between the cold and hot ends of the thermocouple, and it is not significantly affected by other disturbances.
