WRNK-291 Armored thermocouple


WRNK-291 Armored thermocouple as a sensor for measuring temperature It usually used with display instruments, recording instruments and electronic regulators. Can directly measure the temperature of liquid, steam and gas medium and solid surface in the range of 0-800 degrees Celsius in various production processes.

Working principle

WRNK-291 Armored thermocouple consists of two different conductor materials. When there is a temperature difference between the measuring terminal and the reference terminal, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.


1, High mechanical strength and good pressure resistance

2, Less thermal response time reduces dynamic errors

3, Flexible, can be installed and used

4, Large measuring range

Main tech data

1, Graduation: E

2, Product implementation standard: IEC584, GB/T18404-2001

3,Outer diameter:φ3mm,φ4mm,φ5mm,φ6mm,φ8mm

Note: Any special design or question of WRNK-291 Armored thermocouplekindly contact the manufacturer for more details.
