Fast-response temperature thermocouple ISO9001 Wire:Pt-Rh/Wre Head:604/602 Type Fast,accurate and reliability

Fast-response temperature thermocouple

It is usually connected with display meter,recording meter and computer,etc.to directly measure temperature of liquid meteal ranging from 0°c-1820°c 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).
