Platinum rhodium thermocouple is also called high temperature thermocouple, precious metals platinum rhodium have single platinum rhodium (
Platinum rhodium - 10
And double platinum rhodium (
Platinum rhodium - 30
Platinum rhodium (6)
, them as temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, is used to directly measure 0 - or manipulation of the various production process
Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature.
Platinum rhodium thermocouple for precious metals thermocouple.
Accidentally wire diameter provision of 0.
5 mm, allowable deviation -
015 mm, its chemical composition in the name of the positive electrode of platinum rhodium, contain the rhodium was 30%, including platinum was 70%, the negative is extremely platinum rhodium, rhodium for content 6%, therefore, commonly known as the dual platinum-rhodium thermocouple.
The thermocouple * long-term high temperature of 1600 ℃, short-term * high temperature of 1800 ℃.
