Product Details
Description:

Productoverview:
WRN-0313T series Roof type thermocouple A temperature measuring device for power plant boiler roof and other occasions to long distance, high temperature. It is composed of two different electrode conductor material composed of the temperature difference between measuring terminal end with the reference will produce thermal potential, the working instrument will display the temperature value corresponding to the thermal potential. Due to the shape of crown thermocouples often very different, but their basic structures are roughly the same, often by the power pole, the main part of the insulation protection tube and sleeve connection box, and usually display instrument, recording instrument and supporting the use of electronic regulator.
Two, Working principle:
WRN-0313T series Roof type 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.
A thermocouple is used to measure temperature of 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, Applications:
WRN-0313T series Roof type thermocouple Suitable for a power plant boiler roof and other required long distance, high pressure temperature measurement occasions.

Four, main features:

1, simple assembly, convenient replacement;

2, a spring type temperature sensing element, good seismic performance;

3, large measuring range.

Five, Technical parameters:
1, electrical outlet: M16 * 1.5;
2, size: M16 * 1.5;
3, protection grade: lP65.

Six, installation requirements:

The thermocouple installation should pay attention to details; several thermocouples were installed in use; for the temperature measurement is accurate, safe and convenient maintenance, and does not affect the equipment operation and production operation. To meet the following requirements, in the choice of the thermocouple installation position and insert depth should pay attention to the following 2 points:
1, with a protective casing thermocouple heat transfer and heat loss, in order to reduce the measurement error, the thermocouple should have sufficient depth of insertion.
A, when measuring the original insertion depth is more than 1m, should be installed vertically, or installing supporting frame and a protective sleeve.
B, if you need to measure the flue gas temperature is, while the flue diameter is 1000mm, the depth of the thermocouple insert 500mm.
C, for the temperature measurement of fluid pipe center thermocouple, generally the measuring end is inserted into the pipe center (vertical or inclined installation). If the measured fluid pipe diameter is 100 mm, the depth of the thermocouple insert should choose 50~100 mm (should take into account the size installation base or flange).
D, for temperature measurement of high temperature and high pressure and high speed fluid (such as main steam temperature), in order to reduce resistance to the fluid and prevent the protective sleeve to protect the casing fracture under the influence of the fluid, can take the protection tube or shallow inserted by thermal sleeve type thermocouple. Shallow inserted thermocouple protection tube type, which is inserted into the main steam pipeline the depth should be less than 75mm; thermal sleeve type thermocouple standard insert depth 100mm.
2, in order to make the measurement end of thermocouple and measured with sufficient heat exchange medium, should choose a reasonable measuring position, to avoid the valve, elbow and piping and equipment installation thermocouple near the corner.
