Description：

、產(chǎn)品概述：">Productoverview:
WRNG-430 series High temperature and high pressure thermocouple 、化工等生產(chǎn)過(guò)程中的高溫高壓場(chǎng)所的溫度測(cè)量與控制

。">The measurement and control of temperature of high temperature and high pressure place suitable for petroleum and chemical industries in the production process.、高壓聚乙烯等不可缺少的溫度裝置

。">Temperature is an indispensable device for oil refineries, high-pressure polyethylene etc..
、">Two, Working principle：
WRNG-430 series High temperature and high pressure thermocouple ，構(gòu)成一個(gè)閉合回路。">Is the welding of two different material a conductor or semiconductor A and B together to form a closed loop. ，兩者之間便產(chǎn)生電動(dòng)勢(shì),因而在回路中形成一個(gè)大小的電流,這種現(xiàn)象稱為熱電效應(yīng)

。">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. 、并有統(tǒng)一的標(biāo)準(zhǔn)分度表的熱電偶

，主要用于某些特殊場(chǎng)合的測(cè)量。">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. ，并指定S

、R、B

、K、N、E

、J

、T八種標(biāo)準(zhǔn)熱電偶為統(tǒng)一設(shè)計(jì)型熱電偶。">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.

、性能特點(diǎn)：">Four, performance characteristics:

、測(cè)量精度高。">1, high precision measurement. 。">Thanks to direct contact with the object, is not affected by the intermediate medium.

、測(cè)量范圍廣。">2, wide measuring range. ，某些特殊熱電偶zui低可測(cè)到-269℃（如金鐵鎳鉻）

。">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).

，使用方便

。">3, simple structure, convenient use. ，外有保護(hù)套管

，用起來(lái)非常方便。">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.

Six, Structural requirements:
、組成高溫高壓熱電偶的兩個(gè)熱電極的焊接須***牢固

；">Two, high temperature and high pressure thermocouple thermoelectric 1 pole welding must be strong;
，以防短路

；">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;
、保護(hù)套管應(yīng)能保證熱電極與有害介質(zhì)充分隔離

。">4, to protect the casing should be able to guarantee the thermode fully isolated from harmful medium.
