WebSimilarly, ungrounded thermocouple junctions provide a slower response time in exchange for electrical isolation. Figure 5 shows the relative difference in response times for ungrounded and grounded thermocouples. Figure 5. Response Time of Grounded versus Ungrounded Thermocouples ... WebMay 15, 2002 · Apr 19, 2002. #8. If you need fast response use grounded thermocouples. But pay attention to not get more noise than signal. Grounded thermocouple is no problem if you are measuring high temperatures and, you have high output voltages from your thermocouple. But if your environment is very noisy and/or you have low temperatures.

WebOct 20, 2011 · Thermocouple A reads correct values and is unaffected by power and motor being turned on and off. Thermocouple B appears to be picking up voltage from the extruder drive motor when power is supplied. Since the thermocouples output in mV, picking up any voltage from the ground is significantly effecting the temperature readings.
