WebAt the tip of a grounded junction probe, the thermocouple wires are physically attached to the inside of the probe wall. This results in good heat transfer from the outside, through the probe wall to the thermocouple junction. This means that grounded thermocouples will have faster response times than ungrounded thermocouples.
