Platinum Rhodium Thermocouple Conductor Combinations And Characteristics
Type | Thermoelement | Temperature range ℃ | Function Features | |
Advantages | Disadvantages | |||
S | Ptrh10-Pt | 0~1600 | Suitable for oxidation atmosphere. High precision, stability is not affected by using time.With oxidation resistance, chemical corrosion resistance, can be used as standard thermocouple. | Not suitable for reducing atmosphere (especially H2, metal vapor) and vacuum environment, high cost. |
R | Ptrh13-Pt | 0~1600 | ||
B | Ptrh30-Ptrh6 | 600~1700 | Suitable for more than 1000℃,with small thermoelectric, oxidation resistance and chemical corrosion resistance | Can't be used below 600℃, low sensitivity. |
