Angular thermocouple assemblies with threaded elbow tubing (30-WTE) are primarily used for temperature measurement in metal smelting and salt baths. The materials of the protection tubes (pure iron, steel, graphite, titanium or enameled steel) are based on these types of processes.
The right-angled shape guarantees that the connection head is not directly above the fluids. This way the connection head does not come in contact with high temperatures and aggressive fumes. An advantage of this series is the interchangeable protection tube. The inserts of these thermocouples are mineral insulated available or with a ceramic insulated wire element.
Right-angled thermocouples with a threaded right-angled fitting offer the advantages of an exchangeable immersion tube and the possibility of using more economic material for the supporting tube due to reduced ambient stress factors.
Standard assemblies with immersion tubes made of steel, pure iron, heat-resistant steels and special alloys are applied, as well as silicon nitride, graphite, SIC or special metal ceramics.
Optionally, these thermocouple assemblies may be fitted with in an internal ceramic tube, which significantly increases the long-term stability and electrical insulation in many application scenarios.
As an alternative to the installed thermocouple, numerous angular thermocouple assemblies may be fitted with a mineral-insulated gauge slide, which yields several crucial advantages, such as optimal protection of the inner conductors from corrosion, oxidation, physical damage, and chemical contamination due to the enclosed structure of the outer insulation.
In order to ensure functionality of the thermocouple assembly during a suitable timeframe, careful consideration should be used when selecting the materials for thermocouple and protective tube depending on the operating conditions.
Thermoelectric voltages and tolerances of our thermocouples and mineral-insulated gauge slides are pursuant to DIN EN 60584, class 1, for thermocouples and mineral-insulated gauge slides of type L pursuant to DIN 43710.
