High-performance thermocouples are the workhorses of industrial temperature measurement — especially in extreme environments. In this video, we explain how thermocouples work, why they’re ideal for high-temperature, high-pressure, and high-vibration applications, and how to avoid common measurement errors.
You’ll learn:
- What thermocouples are and why they’re used in demanding industries
- How the Seebeck effect enables accurate temperature measurement
- The difference between the hot (measuring) junction and cold (reference) junction
- Common causes of thermocouple measurement errors
- How to prevent issues like incorrect type selection, reversed polarity, ground loops, and reference junction temperature drift
- When to use special limits of error thermocouple wire for improved accuracy
- Why thermocouple aging can cause temperature drift — and when replacement is necessary
Thermocouples are widely used in chemical processing, petrochemical plants, refineries, and other industrial environments where reliability and durability are critical. With proper installation and maintenance, they provide accurate and dependable temperature measurement for most applications.
