Immersion thermocouple (type S,R,B and Wre)is usually connected with display meter,recording meter and computer,etc.to directly measure temperature of liquid meteal ranging from 0-1820 during various steel or iron process.
It has advantage of high accuracy,rapid reaction,reliability and stability.
Structure of thermocouple
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.cardboard (ID 18mm±1mm OD 30±1mm).
