| WR series of armoured thermocouples are designed and produced according to IEC standard. These thermocouples are bendable, pressure-resistable, and have quick response speed. They can be used as temperature sensors of assembling type thermocouples. They can also be installed together with displays and controls to automatically detect and control the temperature of gas, liquid or solid surface. Their working range is from 0ºC to 800ºC. |  |
