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.

TA571 is designed for use with resistance and thermocouple thermometers mainly in heavy duty applications.

• The extension, the immersion and the tapering lengths as well as the bar dimensions can be chosen according to process requirements

• A wide choice of standard materials is available; other versions can be ordered according to specification

• Different grades of surface finishing are also available

• The process connection is welded. The thermowell stem shape can be straight with a conical tip shape
