product description

30 - platinum rhodium Platinum rhodium thermocouple (6 B type thermocouple) For precious metals thermocouple. Accidentally wire diameter provision of 0. 5 mm, allowable deviation - 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 long-term maximum temperature of 1600 ℃, the highest short-term using temperature is 1800 ℃. B type thermocouple in the thermocouple series has the highest accuracy, stability, best measure [area wide, long service life, high temperature limit, etc. Suitable for oxidation and inert atmosphere, can also be short term used in vacuum, but does not apply to reducing atmosphere or containing metal or nonmetal steam atmosphere. B type thermocouple is an obvious advantage don't need a compensation for the compensation conductor, because in the range of 0 ~ 50 ℃ and internal potential less than 3 mu V. B type thermocouple deficiency is thermoelectric potential, thermoelectric potential rate is small, low sensitivity and mechanical strength under high temperature to drop, is sensitive to pollution, precious metal materials is expensive, and one-time investment is larger.

25 Φ B type thermocouple is actual index number for B double platinum rhodium thermocouple, it can measure 0 ~ 1800 ℃ of the temperature of the medium, can be long-term use in 1300 ~ 1600 ℃. Is the best high temperature resistant to high temperature measuring thermocouple.

the main technical parameters of product standards IEC584 IEC751 JB/T5582 - 1991

the order need to know: 1. Indicate the models, index number, using temperature thermocouple. 2. Thermocouple protection tube diameter, length. 3. Fasteners, flange device, provide the size.

company: thermocouples, resistance to high temperature thermocouple, heat resistance, compensation wire, electric stove wire, electric heating, temperature sensors, temperature gauges, etc.
