Mult-Immersion Thermocouple For Foundry
Mult-Immersion Thermocouple For Foundry

Mult- Immersion Thermocouple Type:Pt-Rh/WRe Used 5 times into molten iron High accuracy,rapid reaction and reliability

Mult-Immersion Thermocouple For Foundry is uesd  for measuring the temperature of molten metal.It has advantage of high accuracy,rapid reaction,reliability and stability.

Structure of thermocouple


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)
RQR-KR                    1760°c    0.04
SQR-KS                    1760°c    0.04
BQR-KB                    1800°c    0.04
WReQR-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


1.Response time:less than 5 senconds.

2.ardboard (ID 18mm±1mm OD 30±1mm).
