Product Details
Product Application
Usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of 0 ℃ to 1300 ℃ in various production processes.
Product Features
Less thermal response time, reducing dynamic errors; Flexible installation and use; Large measurement range; High mechanical strength and good pressure resistance.
Product execution standards
IEC584 IEC1515 GB/T16839-1997 JB/T5582-91
working principle:
The electrodes of armored thermocouples are composed of two conductors of different materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.
