High Temperature Thermocouple Probes

High Temperature Thermocouple Probes


Nanmac Corporation has devoted considerable engineering and design energy developing sensors that offer high accuracy and extended life. This applies to relatively low temperature processes such as a chemical mixer at 500?F, pipeline temperatures and plastics moulding, to ultra-high temperatures such as vacuum furnace operation using graphite heating elements for temperatures over 4000?F. The company offers high temperature thermocouple probes ? A12D Series ? with tungsten coated refractory sheath and standard connector attached, or tungsten coated sheath with # 24 ? heavy gage element. Oftentimes a molybdenum sheathed thermocouple is used in a furnace with graphite liners or heating elements. At temperatures above 1600?C, any graphite present emits dust molecules, which attack the sheath and rapidly carburises the sheath. This causes the sheath to become crystallised and porous. The thermal elements lose their protection and they also become crystallised and then break during cycling. Coating the protecting sheath with a thick layer of tungsten minimizes this carburisation process and extends the life of the probes significantly. Field tests at 2000?C using the coated probes produced continuous temperature data up to 2 months, even during cycling, whereas the uncoated probes failed within hours of reaching temperature. Longer life times were also experienced at temperatures below 2000?C.
