High Temperature Irradiation Resistant Thermocouples

技术优势
Rawmaterials cost 0.1% to 75% the cost of raw materials compared to industrystandard for high temperature TCs (Platinum/Rhodium, Tantalum, Nickel alloys) In2016, Niobium cost somewhere less than $100/kg (65%Nb ferritic alloywas $42/kg) and Molybdenumwas $17/kg, compared to over $33000/kg for Platinumand $21000/kg for Rhodium,the two constituents of the industry standard for measuring over 1000 C. Tungsten/Rheniumis $30 and $2500 per kg.Greaterstability at high temperaturesLessdriftSlowerembrittlementSmallerchanges under neutron irradiation than traditional Thermocouple materials

详细技术说明
Researchers at INL havedeveloped methods for forming TCs by swaging the ends of each lead together,avoiding the welding and thermal cycling embrittlement issues that conventionalTCs suffer from. The INL TCs are also made of different materials (Mo-Nb),which are more stable at high temperatures than conventional TC materials. Ofparticular note, these materials are significantly more neutron transparentthan conventional TC materials, making them good candidates for nuclearapplications. Molybdenum and niobium additionally tend to be significantly lessexpensive than traditional TC materials, meaning TCs of this type should beless costly than traditional TCs.
*Abstract

TECHNOLOGYMARKETING SUMMARY:

Accurate measurement ofhigh temperatures (1100-1700° C) is important to safe, efficient, andeconomical operation in many industries. Thermocouples (TCs) are the mostwidely used industrial temperature sensors because they are rugged, affordable,and initially accurate. However, all commercial TCs are unstable in thistemperature range, and are prone to decalibration or “drift”, providingincreasingly unpredictable readings as they age. TCs also typically becomebrittle during prolonged use in this temperature range, leading to mechanicalfailure as they are subjected to system vibration and thermal expansion andcontraction. As a similar problem, TCs are usually welded at the junction, andthe heat of welding can lead to embrittlement and premature failure.

Currently, only a fewtypes of thermocouples, usually made of expensive materials like platinum, canbe used in these temperatures. Solutions to drift include frequent TCreplacement and redundant instrument clusters, both costing significant timeand money.
