WebNov 1, 2024 · The thermocouples were prepared by spot welding the tip of the grown wire to a platinum wire of 99.99% purity, which was the strand of the R-type thermocouple (JIS Class 1). The thermocouple was housed in a two-hole alumina tube (purity: 99.6%). Jan 1, 2014 ·
WebA Feussner thermocouple (iridium : 40 per cent iridium-rhodium) insulated with alumina tubes was placed in an alumina tube furnace, in cracker gas, and heated at 1400°C. The thermocouple was removed for inspection after 24 hours but after a total of 96 hours at temperature the wires broke on removal. WebDESIGN, FABRICATION AND CALIBRATION OF SIX IRIDIUM VERSUS IRIDIUM - 60 RHODIUM THERMOCOUPLES SUMMARY Six iridium versus iridium-60 rhodium thermocouple …
WebIridium-rhodium alloy thermocouples have the two wires made from different alloys of iridium and rhodium. They can measure up to 2000°C in inert atmospheres. Gold-platinum thermocouples are more accurate than pure platinum thermocouples (Types B, R, and S) but can be used only up to 1000°C. WebThe results indicate that the Ir/sup 192/ arises principally rom an (n, gamma ) reaction by thermal neutrons on an Ir/sup 191/ impurity in the thermocouple wires and that this impurity is much larger (>three times) in the Pt- Rh wire than in the Pt wires tested. The ratio of impurity seems to vary from wire to wire.
Web3.11 Iridium-40% Rhodium vs Iridium Being the only rare metal thermocouple that can be used in air without protection up to 2,000°C (short term only), these devices can also be used in vacuum and inert atmospheres. However, there are no standard reference tables, and users must depend upon the manufacturer for batch calibrations.
