Expendable thermocouple
Expendable thermocouple
1.Genenal
K type thermocouple is a sensor for temperature measurement. It can be connected to a fast potentiometer or a digital instrument to measure temperatures of melted iron,steed or other metals.
2.Specification
Type | Calibration no. | Composing Materials | |
+leg(1) | -leg(2) | ||
K | S | PtRh10% | Pt |
K | B | PtRh30% | PtRh6% |
K | R | PtRh13% | Pt |
K | W | Tungsten-3%rhenium | Tungsten-25%rhenium |
Note(1):The +leg means a leg to be connected to +terminal of an instrument to measure thermal electromotive force and -leg means opposite side one.
Type | Calibration no. | Wire diameter (mm) | Max. working temperature°C | Thermal electromotive Force(Mv) |
K | S | 0.05~0.07 | 1650°C | 18.709 |
K | B | 0.05~0.07 | 1750°C | 13.814 |
K | R | 0.05~0.07 | 1700°C | |
