WebA grounded thermocouple has one of the metals in contact with a ground reference, while an ungrounded thermocouple does not. Grounded thermocouples are more common because they are less susceptible to noise and interference. Ungrounded thermocouples are typically used in high-temperature applications where the risk of grounding is too great.
