High temperature and high pressure thermocouple

Productoverview:
WRNG-430 series High temperature and high pressure thermocouple The measurement and control of temperature of high temperature and high pressure place suitable for petroleum and chemical industries in the production process.Temperature is an indispensable device for oil refineries, high-pressure polyethylene etc..
Two, Working principle：
WRNG-430 series High temperature and high pressure 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. Thermocouples use this to work.
3, Thermocouple type:
WRNG-430 series High temperature and high pressure thermocouple Can be divided into standard thermocouple and non standard thermocouple two categories. The so-called standard thermocouple refers to the national standard, the relationship between the thermal potential temperature and allowable error, and indexing table standard thermocouple, which shows its supporting instrument available. Non standard thermocouple in the range of use or magnitude are not standardized thermocouple, in general there is no unified indexing table, mainly used for measuring some special occasions. Standard thermocouple according to IEC international standard production, and designated S, R, B, K, N, E, J, T eight standard thermocouple thermocouple for unified design.

Four, performance characteristics:

1, high precision measurement. Thanks to direct contact with the object, is not affected by the intermediate medium.

2, wide measuring range. The commonly used thermocouple from -50~+1100 C can be continuous measurement, some special thermocouple Zui low detectable -269 C (such as gold iron nickel chromium).

3, simple structure, convenient use. A thermocouple is usually composed of two different metal wires, and the limitation of size and opening, with protective sleeve, it is very easy to use.

Five, Technical parameters:
1: M20x1.5, NPT1/2, electrical outlet;
2: M20x1.5, NPT1/2, connecting dimensions;
3, protection grade: IP65;
4, every burst: D "BT4, D, CT5;
5, nominal pressure: 15-40MPa.
Six, Structural requirements:
Two, high temperature and high pressure thermocouple thermoelectric 1 pole welding must be strong;
Good insulation should be between 2, a power pole each other in case of short circuit;
3, the free end of the thermocouple compensation wire and connected to the convenient and reliable;
4, to protect the casing should be able to guarantee the thermode fully isolated from harmful medium.
Seven, The protection and selection of pipe material:

8, Casing type selection:
The flange can choose 900 (PN15) - 2500LB (PN40) RJ in different forms.

Nine, Flange standard code:

Ten, Type and specification table:

Note: 1, Thermocouple I according to the ordering protocol;
2, the protection tube materials according to ordering protocol
3, the model 430 is waterproof type, type 440 for flameproof type.
Eleven, Design selection and ordering information:
1, model;
2, division no.;
3, precision grade;
4, protection tube material and form;
5, the flange specifications and forms;
6, the length or depth of insertion.
