Expendable Thermocouple( Type R,S ,B)
Expendbale thermocouple (type S,R,B and Wre)is usuallyconnected with display meter,recording meter and computer,etc.todirectly measure temperature of liquid meteal ranging from 0-1820during various steel or iron process.
It has advantage of high accuracy,rapid reaction,reliability andstability.
Structure of thermocouple
Note:
1Protective iron/Al cap
6 refractory cement head or refractory ceramic head
According the different thermocoupe wire,thermocouple has fourtype 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 headcan 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 twotype are common thermocouple wire(P) and exact thermocouplewire(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).
