Introduction
Temperature is a key process variable in many industrial operations. Accurate temperature measurement helps ensure proper process control.
Short Answer
Temperature sensors measure the temperature of fluids, gases, or equipment in industrial processes.
Explanation
Several types of temperature sensors are used in industrial plants.
Common sensors include thermocouples and resistance temperature detectors (RTDs).
Thermocouples are widely used because they can measure very high temperatures.
RTDs are known for their high accuracy and stability.
Engineering Practice
Temperature sensors are often installed in thermowells to protect them from process conditions.
Engineers choose sensors based on temperature range, response time, and accuracy.
Conclusion
Temperature sensors provide critical data for maintaining stable and safe process conditions.
