30-6 thermocouple (b -type thermocouple) For precious metal thermocouples. Thermocouple wire diameter is described as zero.5mm, tolerance -0.015mm, its anode (BP) in the name of the chemical composition of the alloy , wherein the rhodium-containing 30% , 70% platinum , a bad electrode (BN) for the alloy , the quantity of rhodium-containing 6% , so-called twin thermocouple. The long-term maximum temperature of the thermocouple 1600 °, short-term maximum temperature of 1800 °.
b -type thermocoupleThermocouple series has the highest accuracy , the best steadiness , temperature zone width , long life , temperature limit benefits. Suitable for oxidizing and inert environment , a vacuum may even be used for brief-term , but not for a reducing environment or an environment containing a of the metal or metalloid . B -type thermocouple One obvious potential is no deserve to compensate with compensation wire , because within the range of zero ~ 50 ° thermoelectric vigour less than threeμV.
b -type thermocoupleThe draw back is that the thermoelectric vigour , thermoelectric vigour is small , low sensitivity , reduction in mechanical strength at excessive temperatures , is very sensitive to pollution , precious metal costly , so a one-time funding is massive .
b -type thermocoupleModels and specifications :
b -type thermocoupleThe precise number is double that indexing thermocouple B , which can measure the temperature of the medium zero ~ 1800 ° , the long-term use in 1300 ~ 1600 °. Best thermocouple temperature measurement.
