Cangzhou Qirun Detecting Instrument Co.,Ltd.`s now offers Expendable Immersion Thermocouples,used for obtaining molten metal temperature measurements, in the production and refining processes of iron, steel and other ferrous and non ferrous metals
Structure of expendable immersion thermocouples
Note:
1Protective iron/Al cap
6 refractory cement head or refractory ceramic head
According the different thermocoupe wire,thermocouple has four type are S,R,Band WRe Type.
Type | Model | +leg | -leg |
R | QR-KR | PtRh13% | Pt |
S | QR-KS | PtRh10% | Pt |
B | QR-KB | PtRh30% | PtRh6% |
WRe | QR-KW | WRe3% | WRe25% |
Type | Model | Max.working Temperature°c | Wire diameter(mm) |
R | QR-KR | 1760°c | 0.04 |
S | QR-KS | 1760°c | 0.04 |
B | QR-KB | 1800°c | 0.04 |
WRe | QR-KW | 1820°c | 0.1 |
Accroding the different thermocouple connector,thermocouple head can be divide in 602 type and 604 type.
Type | Model |
602(Round bottom) | QR-KR/S/B/W-602 |
604(Triangle bottom) | QR-KR/S/B/W-604 |
Type 602 thermocouple head( Round bottom)and connector
Type 604 thermocouple head(Triangle bottom) and connector
Accroding the different thermocouple wire tolerance,It have two type are common thermocouple wire(P) and exact thermocouple wire(J).
Type | Model | Accuracy |
P(common wire) | QR-KR/S/B/W-604/602P | ≤5°c |
J (exact wire) | QR-KR/S/B/W-604/602J | ≤2°c |
Note:
1.Response time:less than 5 senconds.
2.ardboard (ID 18mm±1mm OD 30±1mm).
