Field of application
The robust thermowell is designed for use in demanding and safety relevant applications e.g. in the Chemical, Oil & Gas and Energy industry. Harsh environments, corrosive substances and highest pressures can be handled by the use of robust protection tubes and special materials.
Designed for use with resistance and thermocouple thermometers in industrial or heavy duty applications.
For increased protection requirements of the temperature sensor regarding physical and chemical effects
For use in pipes and containers or tanks
Ideally suited to all measuring points that require regular recalibration by replacing the insert in closed processes
Benefits
Extension, immersion length and total length can be chosen according to process requirementsModular configuration enable a use in all industrial processes with severe thermal and mechanical stressesFast response time with conical or stepped tip form
