WRNG-440T series Thermocouple cracking furnace The protective tube adopts special structure, so close to the cracking furnace tube inside, and does not affect the material flow. Suitable for measurement and control of temperature in the production process of ethylene cracking furnace.
Two, work principle:
WRNG-440T series Thermocouple cracking furnace Two different components of the conductor ends by welding, forming a loop direct temperature measuring end call measurement end, terminal end call reference end. When there is temperature difference between the measuring terminal and a reference terminal, will produce thermal emf in the circuit, connected to display instrument, the instrument will indicate the corresponding temperature of the thermocouple electromotive force generated by the value of the.
WRNG-440T series Thermocouple cracking furnace The thermoelectric power will increase as the temperature measuring end, thermoelectric sizeonly withthermocouple conductor material and the temperature difference between the two ends, and the hot electrode length, diameter is mainly composed of a junction box, protection tube, insulation casing, terminals, power extremely basic structure, and with various fixed device.
Three, main features:
1, simple assembly, convenient replacement;
2, the pressure spring type temperature sensing element, good anti vibration performance;
3, large range of temperature measurement;
4, high mechanical strength, good pressure resistance.
Four, technical parameters:
1, electrical outlet: M20 * 1.5, NPT1/2;
2, size: M27 * 2, NPT3/4;
3, protection grade: IP65;
Burst level 4: D II, CT6;
5, precision grade: AI.
Five, models and specifications:

Six, Design selection and ordering:
1, indicating the thermocouple type, number, temperature index;
2, the diameter and length of the thermocouple protection tube;
3, fastener, flange, size.
