Thermo-wells are protective devices used in industrial processes to shield temperature sensors from harsh environments. Typically made of durable materials like metal or ceramic, thermo-wells provide a barrier that isolates the sensor from corrosive fluids, high pressures, or abrasive substances. This safeguards the sensor while allowing accurate temperature measurements to be taken without direct exposure to the process conditions. Thermo-wells are essential components in maintaining sensor longevity and process efficiency across various industries.
