Endress+Hauser TW251 | Welded Thermowell with Compression Fitting|Endress+Hauser supplier

The TW251 is a versatile, straight-tube thermowell designed to act as a protective barrier for temperature sensors in both general industrial and hygienic applications. Its defining feature is an integrated compression fitting, which allows for the use of various probe types—such as compact thermometers, cable probes, or modular inserts—typically with a 6 mm diameter. This design provides high flexibility for plant operators, as it enables the removal or replacement of a sensor while the process remains fully sealed and pressurized.

Gambaran Keseluruhan

Kelebihan Teknikal Kritikal

  • Continuous Process Availability: The integrated compression fitting creates a pressure-tight seal around the inserted sensor. If a probe fails or requires calibration, it can be swapped out without suspending the process, draining tanks, or venting pipes.

  • Multi-Probe Compatibility: The TW251 is an “open” platform for sensing. It is compatible with a wide range of 6 mm diameter devices, including the TMR31/TMR35 compact series and various TSC/TPR cable probes. This allows you to standardize your thermowells even if you use different sensor technologies across the plant.

  • Versatile Mounting Options: The sales structure offers a broad array of process connections. You can select standard threads (G 1/2″, NPT 1/2″) for easy installation into existing ports, or choose weld-in versions (cylindrical or spherical) for permanent, high-integrity attachment to vessels and pipes.

  • Specialized Sealing Sleeves: To suit different chemical and thermal requirements, the internal compression sleeve is available in two materials. SS 316 (Stainless Steel) provides a permanent, high-pressure metal-to-metal seal, while PTFE (Teflon) offers excellent chemical resistance and allows for easier adjustment of the probe’s immersion depth.

  • Certified Material Traceability: For regulated industries, the 3.1.B material certificate (EN 10204) is directly selectable. This provides a documented “paper trail” confirming the chemical and physical properties of the stainless steel used in the thermowell’s construction.

Aplikasi Utama
  • Machinery Maintenance: Protecting sensors in oil or coolant lines where frequent sensor replacement is expected due to high vibration.

  • Hygienic Utility Lines: Monitoring water or cleaning fluid temperatures in food plants where a welded or threaded connection is required but 3-A/EHEDG certification for the well itself is sufficient.

  • Retrofit Projects: Using the threaded version to add a protective well to existing pipe T-pieces or vessel nozzles.

  • Chemical Processing: Providing a protective barrier for cable probes in non-corrosive or mildly corrosive gaseous and liquid media.

  • Tank Monitoring: Using spherical weld-in versions to install temperature sensors at an angle on curved tank walls.
