As a sensor for measuring temperature, thermal resistances are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the surface temperature of liquid, steam and gas media as well as solids in various production processes ranging from -200℃ to 500℃.




Application

surface temperature measuring in:

  • energy

  • chemical industry

  • textile

  • other scientific research and production.



Features:

  • High quality temperature sensing elements, stable and reliable performance.

  • High mechanical strength and good pressure resistance

  • High measurement accuracy

  • No need for compensation wires, convenient and economical
