20-TOM

Sheathed thermocouple assemblies without protection tube

Sheathed thermocouple assemblies without protection tube (20- TOM) are used in almost every branch of industry up to a tempera- ture of 1100°C, with a platinum-rhodium-sheath up to 1300°C. Sheathed thermocouple assemblies essentially consist of thermo wires (inner conductors) insulated with high-purity, condensed magnesium oxide powder and an external sheath of heat-resistant high-grade steel or nickel alloy (e.g. Inconel 600®).

Sheathed thermocouple assemblies are available in single, double or triple element version. The outer diameter lies somewhere be- tween 0,5 mm and 8,0 mm depending on technical assembly and customer preference. As a result of their structure, sheathed ther- mocouple assemblies offer numerous advantages when compared to their conventional counterparts.

•  Small dimensions for temperature measurements at measuring sites with difficult accessibility (any desired length available)

•  Short response time for exact measurements of temperature fluctuations

•  Vibration and pressure resistant

•  Optimal protection of inner conductors against corrosion, oxidation, mechanical damage and chemical contamination

•  Increased stability of electric insulation compared to ceramic insulated thermocouples

•  Simple and sealed assembly

Availability

We are able to deliver every current design and diameter of sheathed thermocouple assemblies with mounted sockets, con- nection heads, compensation cables, as well as accessories and mounting structures of every type.

For specialised requirements and standards (such as AMS, CQI-9, etc.), we offer sheathed thermocouple assemblies available with ex- ceptionally narrow tolerances, often referred to as “better class 1”. Thermoelectric voltages and tolerances of our mineral-insulated measuring inserts are according to DIN EN 60584, class 1.
