    What Are Thermowells?

    • Definition: Thermowells are protective enclosures used to shield temperature sensors, such as thermocouples and resistance temperature detectors (RTDs), from harsh process conditions.
    • Purpose: Thermowells help extend the life of temperature sensors by providing a barrier against corrosive materials, high pressures, and high velocities.

    Types of Thermowells

    1. Flanged Thermowells
      • Have a flange for easy installation and removal
      • Ideal for applications where frequent sensor maintenance is required
    2. Threaded Thermowells
      • Screw directly into the process pipeline
      • Suitable for applications with relatively stable process conditions
    3. Socket Weld Thermowells
      • Welded directly into the process pipeline
      • Provide secure and durable sensor protection
    4. Weld-In Thermowells
      • Require welding into the process pipeline
      • Offer robust sensor protection for high-pressure and high-temperature applications
    5. Sanitary Thermowells
      • Designed for sanitary and hygienic applications, such as food and pharmaceutical industries
      • Made with smooth surfaces to prevent bacterial growth
    6. Van Stone Thermowells
      • Are clamped onto the process pipeline using a two-piece flange assembly
      • Allow for easy removal and replacement of the sensor without disrupting the process

    Material Considerations

    • Stainless Steel Thermowells: Corrosion-resistant and suitable for a wide range of industrial applications
    • Brass Thermowells: Cost-effective, but not ideal for corrosive environments
    • Hastelloy Thermowells: Ideal for highly corrosive process conditions
    • Tantalum Thermowells: Resistant to corrosion from acids, making them suitable for chemical processing

    Length and Immersion Depth

    • Length: Choose a thermowell length that ensures the temperature sensor is inserted deep enough into the process to provide an accurate reading.
    • Immersion Depth: Consider the immersion depth to ensure the sensor is adequately protected while still being exposed to the process.
