1.Introduction
T-WRKK -940-BM COT surface thermocouple in ethylene
cracking furnace is most widely used in large-scale
ethylene device of CNOOC and Shell
Petrochemicals,Lanzhou Petrochemical etc.
generally,provided with stable performance and high accuracy measurement.
2.Main Feature
1.Temperature measurement surface thermocouple with protective tube directly welded on the surface of furnace pipe to avoid scouring from extremely flow velocity and damage to measuring element at high temperature,also corrosion to the thermocouple from hydrogen and sulfur.
2.Expanding useful space in installation for special configuration
3.The upper guide pipe could avoid temperature zone on the spot by increasing its length,so as to make the temperature of junction end keep in normal condition,thus assuring high stability and precision in measurement.
