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.
TW15 is designed for use with resistance and thermocouple thermometers in heavy duty applications.
Modular configuration according to DIN 43772 (form 4/4F) enable a use in all industrial processes with severe thermal and mechanical stresses.
Benefits
Extension, immersion length and total length can be chosen according to process requirementsA wide choice of dimensions, materials and process connections is availableSpecial versions can be manufactured according to customer requirementsThe process connection can either be weld-in or flanged
