Thermoelectric properties of compensation conductor should be:
Compensation conductor model | With a thermocouple Degree, | 100 ℃ electric potential nominal value uv | 200 ℃ electric potential nominal value uv | tolerance | materials | ||
Precision level | Regular grade | The anode | The cathode | ||||
SC、RC | S、R | 645 | 1440 | ±10uv | ±60uv | Cu | Cu-Ni |
WC3/25 | WRe3/25 | 1145 | 2602 | ±20uv | ±48uv | Cu | Cu-Ni |
BC | B | Cu | Cu | ||||
WC5/26 | WRe5/26 | 1451 | 3089 | ±51uv | Cu | Cu-Ni | |
Compensation wire specifications: faster production accidentally use 0.4 * 1.0 mm compensating lead wires;General external compensation conductor wire core was 1.0, 5.1 * 8.0 mm outside diameter;Temperature inside the gun with heat compensation conductor wire core was 1.0, diameter 3.1 * 5.6 mm.
