The introduction of high temperature platinum rhodium thermocouple

The introduction of high temperature platinum rhodium thermocouple temperature platinum-rhodium thermocouple is a kind of radical temperature measuring element, has the effect that the thermoelectric stability, oxidation resistance is strong, appropriate USES in oxidation, the inert atmosphere. Temporary using temperature is 1600 ℃, short-term using temperature is 1800 ℃.

have a paper record instrument to the purpose of technology is as follows: 1, the temperature measurement accuracy: & lt; ± 0. 5% t 2, measuring WenFanChou: 0 ~ 1800 ℃, time constant: 180 s 4 or less, insulation resistance: 5 m Ω ( At 20 ℃) 5, size: 500750100, 0120 ( mm） Platinum rhodium thermocouple is also called high temperature thermocouple, precious metals platinum rhodium have single platinum rhodium ( Platinum rhodium - 10 Platinum rhodium) And double platinum rhodium ( Platinum rhodium - 30 Platinum rhodium (6) , such as temperature measurement sensor, usually with temperature transmitter, regulate, and display instrument and other supporting is applied, the process control system, to directly measure or control 0 - in the process of all kinds of consumption 1800 ℃ within the category of fluid, steam and gas medium and solid surface temperature. High temperature platinum rhodium thermocouple for precious metals thermocouple. Rules of wire diameter of 0. 5 mm, allowing the tendency - 0. The positive (015 mm, 英国石油公司(BP) In the name of the chemical composition of platinum rhodium, contain the rhodium is 30%, platinum-based is 70%, the cathode ( BN） For platinum rhodium, rhodium for content 6%, therefore, commonly known as the dual platinum-rhodium thermocouple. The thermocouple temporarily using temperature is 1600 ℃, short-term using temperature is 1800 ℃.
