Product Overview

OBAI-WZ armored thermocouple uses homogeneous conductors (A electrode and B electrode) to form a closed loop. When the two contacts are at different temperatures, current flows through the loop, and a thermal electromotive force exists between the two contacts. This electromotive force is related to the material of the homogeneous conductor and the temperature difference between the two ends. Thermocouples use this principle to measure temperature. It is usually used in conjunction with display instruments, recording instruments, computers, etc. to directly measure the surface temperatures of gases, liquids and solids in the range of 0℃~1700℃ in various production processes.

Main Features

♦Large measuring range and fast response speed
♦Small outer diameter, rapid temperature response
♦High mechanical strength, can be used in environments with vibration, low temperature, and high temperature
♦Simple installation, convenient replacement, long service life
