How to measure metal temperatures with precision
Learn practical methods for determining the mean and local temperatures in metal walls and boiler tubes, with careful calibration to minimize errors.
This edition explains established techniques for placing thermo-couples inside and outside tubes, shielding them from steam and heat, and linking readings to accurate temperature values. It covers calibration routines, two-point and variable-temperature setups, and the interpretation of readings to map temperature along a tube or at interior and surface points. The discussion includes practical challenges, such as avoiding leaks, managing expansion, and selecting materials that resist boiler water and steam.
- How thermocouples and standard cells are arranged to balance signals and read temperature differences
- Methods for calibrating and translating readings into tube temperatures
- Design details for minimizing heat disturbance during measurement
- Examples of experimental setups used to study heat transmission in boilers
Ideal for readers of engineering experiments, boiler design, and applied thermodynamics who want concrete procedures and proven practices.
