Furnace tube blade thermocouple

Productoverview:
WRNK-231D series Furnace tube blade thermocouple The blade type joint directly welded on the surface of furnace pipe for petroleum industrial furnace tube, the tower wall surface temperature measurement. Is the necessary temperature measuring device of refinery distillation tower. Is a special instrument of chlor alkali industry.
Two, work principle:
WRNK-231D series Furnace tube blade thermocouple Two different components of the conductor (called thermocouple wire or thermal electrode) is connected to the two ends of the synthetic circuit, when the junction temperature at the same time, in the loop will produce electromotive force, this phenomenon is called the thermoelectric effect, and this is called thermal electromotive force emf.
WRNK-231D series Furnace tube blade thermocouple The temperature is measured by this principle, which is directly used for measuring the temperature of a medium called the working end (also known as the measuring end), the other end is called the cold end (also known as the end of the cold end compensation); and display instrument or meter display instrument connection, will point out that the thermoelectric potential generated by thermocouple.
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: M20x1.5, NPT1/2;
2, accuracy: I, II;
3, protection grade: IP65;
4, nominal pressure: 10MPa.

Five, installation method:

1, first of all should be measured or the screw thread of the thermocouple flange size, supporting flange or thread processing base.

2, according to the size of the base flange or threaded hole in the pipe, to be measured.

3, the flange or the screw tooth of the welding. The flange or thread is inserted has opened hole in the flange or threaded seat base and pipeline measured welding.

4, the thermocouple with bolts or screw threaded into the base has been welded.

5, according to the wiring diagram to the thermocouple junction box connection, and display instrument is connected on the dial corresponding. Connection box can not contact with the wall of the measured medium pipeline, ensure the junction box temperature not exceeding 100 DEG C. Outlet hole junction box should prevent due to poor sealing, water vapor dust deposition caused by short circuit terminal.

Six, Type and specification table:
