Platinum rhodium expendable thermocouple(S,R,B)


Specifications



Application: Temperature Sensors for Molten Metal



Wire:Pt-Rh/Wre



Tip:**4/**2



Rapid-response type expendable thermocouple is used for measuring the temperature of molten metal.It has advantage of high accuracy,rapid reaction,reliability and stability.



According the different thermocoupe wire,thermocouple has four type are S,R,B,C,D Type.



 Designation Type  



Model Using range recommended （℃） Wire diameter(mm)



 PtRh*0%-Pt    S KS ***0 0.*5



 PtRh*3%-Pt    R KR ***0 0.*5



 PtRh*0%-PtRh6%    B KB ***0 0.*5



 WRe5%-WRe*6%      C KC(KW5/*6) ***0 0.*8



 WRe3%-WRe*5%    D KD(KW3/*5) ***0 0.*8

Accroding the different thermocouple connector,thermocouple tip can be classified as **4 and **2 type.



Type  Model



**2(Round bottom)  KR/S/B/C/D***2



**4(Triangle bottom)  KR/S/B/C/D***4

Accroding the different thermocouple wire tolerance,thermocouple can be classified as common thermocouple wire(P) and precision thermocouple wire(J).



 Type Model     Accuracy
