Thermowell wire refers to a type of wire that is used in conjunction with thermowells, which are protective housings designed to protect temperature sensors (such as thermocouples or RTDs) in industrial processes. Thermowells help shield temperature measurement devices from harsh environments, high pressures, corrosive chemicals, and mechanical damage while still allowing for accurate temperature readings.

Temperature Range: Ensure the wire can handle the maximum and minimum temperatures of the process.

Corrosion Resistance: Select a wire material that is resistant to corrosion from chemicals or environmental factors.

Insulation: Choose the appropriate insulation material (e.g., silicone, fiberglass, Teflon) based on the application and temperature.

Flexibility: Determine if the wire needs to be flexible or rigid based on the installation environment.

Signal Integrity: Choose wire materials with low resistance and high conductivity to ensure that signals from the sensor are transmitted accurately.
