SUMMARY

The discussion centers on issues related to inaccurate temperature readings from T type thermocouples. Users report that the thermocouple displays higher temperatures when immersed in ice and lower temperatures in hot water. The conversation emphasizes the importance of matching the temperature measuring device with the thermocouple type and understanding the data acquisition (DAQ) setup used for measurements.

PREREQUISITES
  • Understanding of T type thermocouples and their characteristics
  • Familiarity with data acquisition (DAQ) systems
  • Knowledge of temperature measurement instruments and their compatibility with thermocouples
  • Basic understanding of thermocouple calibration and error sources
NEXT STEPS
  • Research the specifications and calibration methods for T type thermocouples
  • Explore different types of data acquisition systems and their compatibility with thermocouples
  • Learn about common errors in temperature measurement and how to troubleshoot them
  • Investigate the impact of connection methods (Ethernet, USB, wireless) on temperature readings
USEFUL FOR

Engineers, technicians, and researchers involved in temperature measurement and instrumentation, particularly those working with thermocouples and data acquisition systems.

Hello,

Has anybody used it before? I am having trouble regarding readings it is giving me.. It seems to raise the temp when T type thermocouples are dipped in ice and lower the temp when dipped in hot water.. numbers don't make sense to me. Please help

Can you post a lot more info on your DAQ setup? What instrument are you using to measure the temperature? How are you connecting to it (Ethernet, USB, wireless, etc.)? What type of thermocouple are you using, and are you sure your temperature measuring device matches that thermocouple type?
