WebThese ground paths can act as a large loop antenna that causes noise to be picked up from the environment, inducing currents in the grounding system. The 50 Hz/60 Hz magnetic field from ac power is a common source of the noise that ground loops pick up. WebHowever, grounded thermocouples are highly susceptible to noise induced by ground loops, resulting in less accurate readings. Ungrounded Junction Thermocouples In an ungrounded probe, the thermocouple junction is detached from the probe wall. Response time is slower than the grounded style.
