Thermowells for Industrial Temperature Measurement
Thermowells provide essential mechanical protection for RTDs and thermocouples in high-pressure, high-velocity and corrosive industrial applications. By isolating the temperature sensor from the process, thermowells ensure long service life, safe maintenance and reliable temperature measurement in demanding environments.
What Thermowells Are Designed For
Thermowells are used wherever temperature sensors must be protected from:
- High process pressure
- High flow velocity or vibration
- Corrosive or abrasive media
- Frequent sensor replacement
- Hazardous or hygienic environments
They allow the sensor to be removed for maintenance without depressurising or opening the process line.
Why Engineers Choose Thermowells
- Protect sensors from mechanical and chemical damage
- Enable safe removal and replacement of sensors
- Extend sensor lifespan in harsh environments
- Suitable for extreme temperatures and pressures
- Available in multiple materials and process connections
- Compatible with all TM Series sensors
