Field of application
Due to the challenging process conditions by heavy duty applications the load capacity of a thermowell must be calculated exactly. Dye penetration tests, ultrasound test, helium leakage test, pressure endurance test as well as various, non-destructive material tests prove the quality of materials and processing.
TA565 is designed for use with resistance and thermocouple thermometers mainly in heavy duty applications.
Benefits
The extension and the immersion length as well as the bar dimensions can be chosen according to process requirementsA wide choice of standard diameters and materials is available; other versions can be ordered according to specificationDifferent grades of surface finishing are also availableThe process connection is threaded. The thermowell stem shape can be straight or conical
