MI Thermocouple Cable is widely used in many industries and fields, including industrial furnaces, chemical plants, power equipment, metallurgical engineering and laboratories, etc. It can be used to monitor and control the temperature of various heating equipment, kilns, reactors and experimental devices to ensure the stability and safety of the process.
Regarding parameters, MI Thermocouple Cable models and specifications vary from manufacturer to manufacturer. Common parameters include temperature range, wire diameter, mineral insulation, cable length, and available thermocouple types. These parameters can be selected according to specific application needs to meet different temperature measurement requirements.
