Product Description

Expendable Thermocouple

1.Genenal

K type thermocouple is a sensor for temperature measurement. It can be connected to a fast potentiometer or a digital instrument to measure temperatures of melted iron, steel or other metals.

2.Specification

Type	Calibration no.	Composing Materials
Type	Calibration no.	+leg(1)	-leg(2)
K	S	PtRh10%	Pt
K	B	PtRh30%	PtRh6%
K	R	PtRh13%	Pt
K	W	Tungsten-3%rhenium	Tungsten-25%rhenium

Note(1):The +leg means a leg to be connected to +terminal of an instrument to measure thermal electromotive force and -leg means opposite side one.

Type	Calibration no.	Wire diameter (mm)	Max. working temperatureºC	Thermal electromotive Force(Mv)
K	S	0.05~0.07	1650ºC	18.709
K	B	0.05~0.07	1750ºC	13.814
K	R	0.05~0.07	1700ºC
K	W	0.1	1800ºC

Response time:less than 5 seconds.
