Thermocouple assemblies for welding with thermowell form 4 (former D-sleeve) according to DIN 43772
Thermocouple assemblies for welding (12-THD) are used in gas- eous or liquid media such as air, steam, water, oil, etc. with high current speeds and pressure. The thermowell’s material defines the operating temperature. Specialized assemblies for welding are suit- able for up to 700 bar of pressure. The mountings of this product line are fitted with exchangeable gauge slides.
The main component is a thermowell crafted from high-grade or pressure-vessel steel, with which the thermocouple assembly is welded to the respective machine or measuring location.
Selection of the thermowell is dependent on spatial proportions at the point of installation, as well as demands as dictated by tem- perature, pressure, current flow and chemical attack.
Standard values for stress capacity can be found in the diagrams of DIN 43772.
In particular the question of chemical stress capacity must be ex- amined carefully for each individual scenario. Often times, only field testing will yield authoritative information, as even minor impurities in the ambient media can have significant impact on the perfor- mance of the thermowell within the application environment.
Thermoelectric voltages and tolerances of our thermocouples and measuring inserts are according to DIN EN60584, class 1.
