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.

TA556 is designed for use with resistance and thermocouple thermometers mainly in heavy duty applications.

• The extension and the immersion lengths as well as the bar dimensions can be chosen according to process requirements
• A wide choice of standard materials and process connections is available; other versions can be ordered according to specification
• Different grades of surface finishing are also available
• The thermowell stem shape is stepped
• The process connection can be threaded or flanged weld
