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.
TA562 is designed for use with resistance and thermocouple thermometers mainly in heavy duty applications.
Benefits
The thermowell stem shape can be straight or reduced for fast response timeExtension, immersion length and reduced length as well as the bar dimensions can be chosen according to process requirementsDifferent grades of surface finishing are also availableThe process connections are threaded: ½”NPT, ¾”NPT, G½” or M20x1.5A wide choice of standard materials is availableSpecial versions can be manufactured according to specification
