Seeking help with issues regarding ground thermocouples
Thread Content
Ground-type K thermocouples are used on site; I’m not sure why foreign designers opt for ground-type thermocouples. Is the grounding sensitivity high? What is the difference from being ungrounded? Thank you
Please describe your installation environment; in general, such situations require consideration of the actual conditions on site
Ground-type thermocouples are used: First, for temperature control systems, to ensure that the inertance detected by the thermocouple is as low as possible, ground-type thermocouples are employed, in which the thermocouple wire is welded to a metal sleeve. In other words, the sensitivity will be high, as the original poster said. Secondly, grounding is done to suppress interference; for example, when using a thermocouple to measure the temperature of an electric furnace, in order to overcome the interference caused by leakage current, the end of the thermocouple is grounded so that it is at the same potential as the ground, thereby preventing leakage current from occurring. If there are other reasons, please feel free to add them, fellow sailors.
