35-WGG

Right-angled thermocouples welded or curved out of one segment

Right-angled thermocouples welded or curved out of one segment (35-WCG) are primarily used for temperature measurement in metal smelting and salt baths.

These thermocouples are, in contrast to the 30-WTE series, not divisible but they are composed out of one material, without any thickening. 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. The inserts of these thermocouples are mineral insulated available or with a ceramic insulated wire element.

Technical specifications

As an alternative to the conventional thermocouples, numerous angular thermocouple assemblies may be fitted with a mineral-insulated gauge slide, which can have several crucial advantages:

  • Optimal protection of the inner conductors from corrosion, oxidation, physical damage, and chemical contamination due to the enclosed structure of the outer insulation.
  • Increased stability of the electrical insulation compared to ceramic insulated thermocouples.

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.
