E,H压力变送器选型手册
E,H压力变送器选型手册各位读友大家好！你有你的木棉，我有我的文章，为了你的木棉，应读我的文章！若为比翼双飞鸟，定是人间有情人！若读此篇优秀文，必成天上比翼鸟！篇一：关于E+H产品选型方法与型号说明重要内容，请看第2页1、登录德国E+H（全称：Endress+Hauser，中文：恩德斯豪斯）网站/ 2、点击“Asia”（亚洲）3、点击“China”（中国）4、点击“产品” 5、选择你需要了解或购买的产品，如我需要了解订货号10H1H-UF0A1AG4A5AA 与10H1H-1F0A1AG4A4AA的区别，则按照以下“流量——电磁流量计——Promag H——Promag 10H——产品比较（同一系列不一样型号的信息）或者产品选型（同一型号不同订货号的信息）”，详细请看下面的截图。
查询结果：综下所属，订货号10H1H-UF0A1AG4A5AA与订货号10H1H-1F0A1AG4A4AA两个传感器可以互换，但一定要把变送器里的数据模块换过来（上面是传感器工厂标定的数据），区别仅在过程连接（第1个符号所表示）与电源（第10个符号所表示）不一样。
详解如下：第1个符号表示传感器过程连接“U”代表焊接螺纹接套DIN11850, 316L/1.4404“1”代表Tri-Clamp, 316L/1.4404 关于Tri-Clamp：即TC快速接头(Tri-clamps)常用于啤酒、乳业、饮料、制药等领域接头，材质一般为不锈钢，同时Tri-Clamp 也是Alfa-Laval 集团Tri-Clover 有限公司的注册商标，也称卫生级接头，卫生级管道在食品、医药等生产中洁净要求高的场合广泛采用，生产工艺要求无死角连接，且易清洗，一般情况下压力都不高，也就是俗称的“卡箍”连接，常用的TC接头有焊接端头（２个），垫圈和快装卡箍四个零件组成．市场上很容易买到。
TC 接头详细规格可以参考DIN 32676-2001 饮食业、化工业和医药业用配件.不锈钢管夹具接头.焊接式，德国的标准，看看接头和卡箍的图片，连接好后的样子标准中给出了。

INTRODUCTIONLT LVPLESTSLOHBGROMCZSK2. HANDLING CAUTIONS 2.HANDLING CAUTIONSThis chapter describes important cautions regarding how to handle the transmitter. Read carefully before using the transmitter.The EJA Series pressure transmitters are thoroughly tested at the factory before shipment. When the transmitter is delivered, visually check them to make sure that no damage occurred during shipment.Also check that all transmitter mounting hardware shown in Figure 2.1 is included. If the transmitter was ordered without the mounting bracket or without the process connector, the transmitter mounting hardware is not included. After checking the transmitter, repack it in the way it was delivered until installation.(Flat type)F0201.EPS Figure 2.1 Transmitter Mounting Hardware2.1Model and SpecificationsCheckThe model name and specifications are indicated on the name plate attached to the case. If the reverse operating mode was ordered (reverse signal), ‘REVERSE’ will be inscribed in field *1; if square root display mode was ordered, ‘SQRT’ is inscribed in field *2; if square root output mode was ordered, ‘SQRT’ is inscribed in field *3.F0202.EPS Figure 2.2 Name Plate Example of TIIS Flameproof Type 2.2UnpackingWhen moving the transmitter to the installation site, keep it in its original packaging. Then, unpack the transmitter there to avoid damage on the way.2.3StorageThe following precautions must be observed when storing the instrument, especially for a long period. (a)Select a storage area which meets the followingconditions:•It is not exposed to rain or water.•It suffers minimum vibration and shock.•It has an ambient temperature and relativehumidity within the following ranges.Ambient temperature:–40 to 85°C without integral indicator–30 to 80°C with integral indicatorRelative humidity:5% to 100% R.H. (at 40°C)Preferred temperature and humidity:approx. 25°C and 65% R.H.(b)When storing the transmitter, repack it as nearly aspossible to the way it was packed when deliveredfrom the factory.(c)If storing a transmitter that has been used, thor-oughly clean the chambers inside the cover flanges, so that no measured fluid remains in it. Also make sure before storing that the pressure-detector andtransmitter section are securely mounted.2.4Selecting the InstallationLocationThe transmitter is designed to withstand severe environmental conditions. However, to ensure stable and accurate operation for years, observe the following precautions when selecting an installation location.2. HANDLING CAUTIONS(a) Ambient TemperatureAvoid locations subject to wide temperaturevariations or a significant temperature gradient. If the location is exposed to radiant heat from plant equipments, provide adequate thermal insulation and/or ventilation.(b) Ambient AtmosphereAvoid installing the transmitter in a corrosiveatmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequateventilation as well as measures to prevent intrusion or stagnation of rain water in conduits.(c) Shock and VibrationSelect an installation site suffering minimum shock and vibration (although the transmitter is designed to be relatively resistant to shock and vibration).(d) Installation of Explosion-protected Transmitters Explosion-protected transmitters can be installed in hazardous areas according to the types of gases for which they are certified. See Subsection 2.9 “Instal-lation of Explosion Protected Type Transmitters.”2.5Pressure ConnectionWARNING•Instrument installed in the process is under pressure. Never loosen the process connector bolts to avoid the dangerous spouting of process fluid.•During draining condensate from the pressure-detector section, take appropriate care to avoid contact with the skin, eyes or body, or inhala-tion of vapors, if the accumulated process fluid may be toxic or otherwise harmful.The following precautions must be observed in order to safely operate the transmitter under pressure.(a)Make sure that the four process connector bolts are tightened firmly.(b)Make sure that there are no leaks in the impulse piping.(c)Never apply a pressure higher than the specifiedmaximum working pressure.CAUTIONMaximum working pressure of the model EJA120differential pressure transmitter is 50 kPa {0.5 kgf/cm 2}.Should the pressure exceed 50 kPa {0.5 kgf/ cm 2},it is possible to break the sensor. Proceed with caution when applying pressure.2.6Waterproofing of CableConduit ConnectionsApply a non-hardening sealant to the threads towaterproof the transmitter cable conduit connections.(See Figure 6.4.2a, 6.4.2b and 6.4.2d.)2.7Restrictions on Use of RadioTransceiverIMPORTANTAlthough the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter or its external wiring, the transmitter may be affected by high frequency noise pickup. To test for such effects, bring the transceiver in use slowly from a distance of several meters from the transmitter,and observe the measurement loop for noise effects. Thereafter, always use the transceiver outside the area affected by noise.2.8Insulation Resistance andDielectric Strength TestSince the transmitter has undergone insulation resis-tance and dielectric strength tests at the factory before shipment, normally these tests are not required.However, if required, observe the following precau-tions in the test procedures.(a)Do not perform such tests more frequently than is absolutely necessary. Even test voltages that do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.(b)Never apply a voltage exceeding 500 V DC (100 V DC with an internal lightning protector) for the insulation resistance test, nor a voltage exceeding 500 V AC (100 V AC with an internal lightning protector) for the dielectric strength test.(c)Before conducting these tests, disconnect all signal lines from the transmitter terminals. Perform the tests in the following procedure:• Insulation Resistance Test1)Short-circuit the + and – SUPPLY terminals in the terminal box.2)Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the shorted SUPPLY terminals and the minus (–) leadwire to the grounding terminal.。
