差压变送器正确操作使用步骤变送器如何操作对于工业上大部门的差压变送器，不管是HART协议和布朗协议等差压变送器，安装与调校应注意以下几个问题：1、正确进行误差及回差的计算，正确给出校验结论，正确给出校验结论，正确进行有效数字的处理。
2、设备复位整理：停用三阀组，停电、拆除回路连线及相关设备，压力掌控台启动关闭，打开截止阀及回检阀。
3、校验仪设置功能项，校验仪首先清零，压力管路连接好，同时注意正负极连接，接入标准电阻。
检查回路电流。
4、变送器精度校验：将微调阀放到中心位置，关闭截止阀及回检阀，电动压力检验台输出压力设置，基本误差调校（上行5点，下行5点），适时记录数据。
5、安装时候常常显现松动，变送器与三阀组链接，螺栓应对角缩紧，一般不能一次锁死，三阀组安装时候应当加密封线圈。
6、正确的挂接手操器，依照要求设置变送器内容，零位调整。
7、对于三阀组的操作：首先打开平衡阀，正确开高压阀。
差压变送器在测量过程中常会显现一些故障，因此，在确定程度上影响生产的正常进行，依据相关人员现场多年的实践阅历，总结了一些常见故障判定分析和解决方法。
线路故障：当计算机显示数值不正常时，首先要打开智能差压变送器的接线盒，检查线路是否虚接、短接或者断接，可以通过测电源、量电阻、摇绝缘等方法，进行故障的判定和处理。
采集模块或差压传感器故障：当线路故障排出时，就要看是不是采集模块或差压传感器故障。
使用万用表检查智能差压变送器工作电源是否正常，同时测量智能差压变送器的输出电流值是否在4mA～20mA（假如为输出电压值，测量是否在0～5V）范围内，确认输出值是否正常。
假如无输出值，智能差压变送器损坏，需要更换差压变送器。
假如现场测量值换算与实际阅历值相符，则现场仪表和测点无问题，模块损坏，需更换模块。
当现场测量值换算与计算机显示值相同，说明引压管或智能差压变送器有问题。
引压管故障：1.引压管漏气—由于差压变送器接点、截止阀等附件比较多，导致泄漏点增多，维护工作量增大。

Here, the "Low demand mode" has been observed, i.e. the requirement rate for the safety-related system is maximum once a year.Sensor, logic unit and actuator together form a safety-related system, which performs a safety function. The "Average Probability of Failure on Demand" (PFD AVG ) is usually divided up into the sensor, logic unit and actuator sub-systems as per Figure 1.Fig. 1: usual division of the "Average Probability of Failure on Demand" (PFD AVG ) into the sub-systems!Note!This documentation considers the TMT162 as a sensor sub-system.Standard ExplanationIEC 61508,Part 1 – 7Functional safety of electrical/electronic/programmable electronic safety-related systems (Target group: Manufacturers and Suppliers of Devices)IEC 61511Part 1 – 3 (FDIS)Functional safety – Safety Instrumented Systems for the process industry sector (Target group: Safety Instrumented Systems Designers, Integrators and Users)Term ExplanationDangerous failureFailure with the potential to put the safety-related system in a dangerous or non-functional condition.Safety-related systemA safety-related system performs the safety functions that are required to achieve or maintain a safe condition e.g. in a plant.

Type B systems are, for example, sensors with complex components such as ASICs (→ see also IEC 61508, Part 2).Safety function with TMT162Safety function for limit temperature monitoringFig. 2: safety function (e.g. for limit temperature monitoring) with TMT162 as sub-systemThe TMT162 transmitter generates an analogue signal (4...20 mA) proportional to the temperature. The analogue signal is fed to a downstream logic unit, such as a PLC or limit signal generator, and there it is monitored to determine whether it exceeds a maximum value. In order to monitor for faults, the logic unit must be able to detect both HI-alarms ≥ 21.6 mA and LO-alarms ≤ 3.6 mA.Safety function data"Caution!The data for the safety functions are listed in the "Safety-related parameters" chapter.!Note!MTTR is set at eight hours.Safety-related systems without a self-locking function must be monitored or set to an otherwise safe state after carrying out the safety function within MTTR.Unit versionHardware assessment valid from Hardware Revision: 1.01.00 and Software Revision: 1.02.01Supplementary device documentation TMT162Depending on the version, the following documentation must be available for the temperature transmitter iTEMP ® HART ® 162:Safe Failure Fraction (SFF)Hardware Fault Tolerance (HFT)012< 60%not permitted SIL 1SIL 260 ...< 90 %SIL 1SIL 2SIL 390 ...< 99 %SIL 2SIL 3–≥ 99 %SIL 3––Explosion protection/Certificates Operating instructions Other Ex-Documentation noneBA132R noneATEX II 1 G EEx ia IIC T4/T5/T6BA132R Safety instructions XA033R ATEX II 2 G EEx d IIC T6BA132RSafety instructions XA031RiTEMP® HART® TMT1626Endress+Hauser"Caution!•The installation and setting instructions, and the technical limit values must be observed in accordance with the Operating Instructions (BA132R).•For devices which are used in explosion-hazardous, the supplementary documentation (XA) resp.

压力温度变送器操作规程温度变送器同压力变送器的操作使用基本相同，压力变送器下有二阀组（三阀组），温度变送器则无，下面主要讲述压力变送器的操作规程。
1检查和准备1.1压力变送器安装的环境温度和压力必须符合规定。
1.2通电前，仔细检查电源的正负极性，不要接错，供电电压应在正常范围内。
1.3拆卸压力变送器时，必须断开24VDC电源，并做好接线标记。
关闭该压力变送器的取压阀，然后断开现场仪表电源线，同时做好接线标记和接线头的绝缘保护。
1.4注意电缆接头的密封塞和电缆是否出现松动和老化现象，以便防尘防水。
1.5防爆铭牌清晰完好。
1.6严禁在危险场所开盖。
1.7每月检查一次检查引压管线有无渗漏。
1.8每半年进行一次仪表零位检查和量程检查。
1.9每年检定一次。
1.10每月检查一次两侧表盖是否拧紧，密封圈是否老化。
1.11每月检查一次防爆接头密封性检查。
1.12日常检查应校核压力变送器测量值是否准确，否则及时上报生产科进行处理。
2操作内容和步骤2.1（压变的启用）操作2.1.1检查各引压管及仪表电源线都连接好，三阀组处于切断状态。
2.1.2打开三阀组的平衡阀。
2.1.3开启压力变送器三阀组连接正、负压室的针形阀门。
2.1.4快速开启放空阀，排出管内的积液然后关闭。
2.1.5然后关闭平衡阀，变送器投入正常工作。
2.2停用压力变送器操作2.2.1打开三阀组的平衡阀，使变送器的正、负压室压力平衡。
2.2.2关闭正、负压室的截断阀，这时仪表表头指示应回零。
2.2.3打开放空阀，放空三阀组。
3操作后检查3.1检查开启三阀组后各连接管路是否漏气，表头指针指示是否正常。
3.2检查停用三阀组后仪表表头指示是否回零。
4风险提示及削减措施4.1风险提示：引压管线出现渗漏，引起爆炸。
削减措施：1）加强对各连接部件的检漏；2）定期对压力变送器的维护保养。
5维护保养为了保证变送器的测量精度和使用寿命，应定期地对变送器运行状态进行检查。
（1）外观检查目视检查变送器各部件有没有损伤、腐蚀现象。
