Furnace wall thermocouple
Description:
Productoverview:
WRNK-191M series Furnace wall thermocouple Mainly used for boiler tube wall, the furnace wall and other cylinder surface temperature measurement. The armoured element 3-6MM, as a measurement probe, with compensation cable (Yan Changxing), the measuring end welded or bolted in stainless steel sheet composed of temperature. Is the use of armoured elements 4, Phi Phi 5 diameter as temperature probe, lead wire made of cable shape, measuring end screws or welding method of fastening on the heat conducting plate (when using thermal resistance, no welding method), a heat conducting plate is provided with a curved surface matched with the furnace wall or pipe, heat conducting plate by welding or hoop (pipe) in the furnace wall, the heat conduction plate, can measure the wall or other cylindrical surface temperature.
Two, Structure principle:
WRNK-191M series Furnace wall thermocouple Is the welding of two different material a conductor or semiconductor A and B together to form a closed loop. When two points of attachment conductor A and B 1 and 2 between the temperature difference between the two, will produce electromotive force, thus forming a size of the current in the circuit, this phenomenon is called the thermoelectric effect. The furnace wall thermal resistance is to use this effect to work.
Three, wide Application:
WRNK-191M series of professional power plant furnace wall thermocouple design, can meet the 300 thousand and 600 thousand KW generator set and auxiliary measurement needs. Direct measurement of the production process of -200 degrees ~800 degrees within the range of liquid, steam, gas and solid surface temperature.
Four, Main features:
The thermal response time, reduce the dynamic error;
Flexible installation;
Large measuring range;
High mechanical strength, good pressure resistance;
Five, Structural requirements:
Two, the composition of thermocouple thermoelectric 1 pole welding must be strong;
Good insulation should be between 2 and two thermode each other, to prevent short circuits;
3, and the free end of the thermocouple compensation wire connection is convenient and reliable;
4, to protect the casing should be able to guarantee the thermode fully isolated from harmful medium.
Six, Technical parameters:
1, accuracy: class I and ii;
2, nominal pressure: pressure;
3, bending radius: R = 5D.
