智能压力变送器由智能传感器和智能电子板两部分组成，智能传感器部分包括：电容式传感器、测量膜片检测电路、温度传感器和温度补偿电路等组成；智能电子板板部分包括：微电脑控制器及外围电路组成，用于测量液体、气体或蒸汽的压力，然后将压力信号转变成4～20mADC信号输出。可与HART手操器相互通讯，通过它进行设定，调整压力范围，监控或与上位机组成现场监控系统，JSHJ-3851智能压力变送器广泛应用于工业管道中弱腐蚀性液体、气体、蒸汽的测量和控制系统。

 

　　The intelligent pressure transmitter is composed of two parts:an intelligent sensor and an intelligent electronic board.The intelligent sensor part includes:a capacitive sensor,a measuring diaphragm detection circuit,a temperature sensor and a temperature compensation circuit;the intelligent electronic board part includes:a microcomputer controller And peripheral circuit composition,used to measure the pressure of liquid,gas or steam,and then convert the pressure signal into 4-20mADC signal output.It can communicate with the HART handheld operator,through it to set,adjust the pressure range,monitor or form an on-site monitoring system with the host computer.The JSHJ-3851 intelligent pressure transmitter is widely used in industrial pipelines for weak corrosive liquids,gases,Steam measurement and control system.

　　Installation instructions for smart pressure transmitter:

 

　　1、变送器应安装于通风、干燥、无蚀、阴凉处，如露天安装应加防护罩，避免阳光照射和雨淋，否则将会使变送器性能降低或出现故障。

 

　　1.The transmitter should be installed in a ventilated,dry,non-corrosive,and shady place.If installed in the open air,a protective cover should be added to avoid sunlight and rain,otherwise the performance of the transmitter will be degraded or malfunctions.

 

　　2、变送器利用压力接口螺纹（标准配置为M20×1.5）直接安装在被测系统的管道或容器壁上，不必使用安装支架。产品压力接口（标准配置）备有密封槽，被测压力较大时，加装尼龙或紫铜垫片可保证良好密封。

 

　　2.The transmitter is directly installed on the pipe or container wall of the system under test by using the pressure interface thread(standard configuration is M20×1.5),without using a mounting bracket.The product pressure interface(standard configuration)is equipped with a sealing groove.When the measured pressure is large,a nylon or copper gasket can be added to ensure a good seal.

 

　　3、安装变送器时，请注意须使电缆与产品同向转动，否则，会影响产品的防护效果并导致产品故障。

 

　　3.When installing the transmitter,please make sure that the cable and the product rotate in the same direction,otherwise,the protection effect of the product will be affected and the product will malfunction.

 

　　4、零点（Z），量程（S）可调产品调试方法：拧开标有需调整参数点的螺丝，用小螺丝刀伸入其中，轻轻转动可调电阻，并同时监控数据，调试完毕，拧紧螺丝，以免潮气进入。

 

　　4.Zero point(Z),range(S)adjustable product debugging method:unscrew the screw marked with the parameter point to be adjusted,insert it with a small screwdriver,gently turn the adjustable resistance,and monitor the data at the same time,after the debugging,tighten it Screws to prevent moisture from entering.

 

　　5、变送器属精密仪器，安装时忌强力冲击、摔打，拧紧力矩应小于70Nm，小量程变送器（量程小于0.5MPa）拧紧力矩应小于14Nm.注意保护变送器引出电缆。在工业现场使用时，建议使用金属管保护或者架空。切勿松动电缆引出端的密封螺帽，避免潮气进入。

 

　　5.The transmitter is a precision instrument.Avoid strong impact and beating during installation.The tightening torque should be less than 70Nm,and the tightening torque of small range transmitters(range less than 0.5MPa)should be less than 14Nm.Take care to protect the cables leading from the transmitter.When used in industrial sites,it is recommended to use metal pipe protection or overhead.Do not loosen the sealing nut on the lead-out end of the cable to prevent moisture from entering.
