Right angle bend thermocouple

Productoverview:
WRN-530 series Right angle bend thermocouple Suitable for the production site has high temperature and harmful gases have influence on the thermocouple junction box, or not directly horizontal and vertical installations. A thermocouple uses 90 degree angle, avoid direct exposure to the thermocouple junction box is at the top of the stove, can avoid the temperature error of thermocouple. Temperature sensor WR series industrialthermocouple as usual, with the regulator and display instrument supporting temperature transmitter, composition, process control system, steam and gas medium and solid surface temperature, fluid by direct measurement or control of various production processes within the range of 0-1800 DEG C.

Two, work principle:
WRN-530 series Right angle bend thermocouple It is composed of two different components of the grounding conductor ends of synthetic circuit, when the two junction temperature at the same time, it will produce thermal current in the loop. If the working end and the reference thermocouple endthere is atemperaturedisplay, will be a corresponding display instrument instructions from thermocouples thermoelectric temperature value.
Various thermocoupleappearanceoftenbecause the needs and not the same, but their basic structures are roughly the same, usually composed of a thermal insulating sleeve, electrode protection tube and terminal box main components.
Three, application:
WRN-530 series Right angle bend thermocouple Applicable to the production site of high temperature and harmful gases have influence on the thermocouple junction box, or not directly horizontal and vertical installations.

Four, 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.

Five, technical parameters:
1: M20x1.5, NPT1/2, electrical outlet;
2: I, II, precision grade;
3, protection grade: IP65;
4. nominal pressure: pressure.

Six, temperature measurement range and allowable error:

notes "T" For a sense of measured temperature of temperature sensor.

Seven, thermal response time:
In the temperature step change occurred, the output variation of the thermocouple to the equivalent of the 50% changes, the time needed to say is thermal response time, denoted by T0.5.
The nominal pressure of eight, thermocouple:
Generally refers to the protective tube can withstａnd at room temperature under the condition of static pressure without rupture. In fact, not only the allowable working pressure and protection of pipe material, diameter and wall thickness, but the structure, installation method, insertion depth and the measured velocity and type of medium etc..
Small insertion depth of thermocouple Zui
The protection should be not less than 8~10 times the diameter (special exception).
The insulation resistance of the thermocouple (room temperature)
Room temperature insulation test voltage of resistance for DC 500V + 50V, insulation resistance measurement of atmospheric conditions at room temperature for 15~35 degrees Celsius temperature, relative humidity of 45%, atmospheric pressure is 86 ~ 106kPa.
A. for more than 1 meters in length the thermocouple at room temperature insulation resistance value and the length of the product should not be less than 100.
That is Rr.L = 100 M. M L, 1M
Type: Rr- thermocouple temperature insulation resistance value of M.
B. for a length equal to or less than 1 meters of the thermocouple, its temperature insulation resistance shall not be less than 100 M.
The upper limit temperature of insulation resistance.

Nine, 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.
