智能压力变送器压力偏高如何处理?

作者:华恒仪表 发布日期: 2020-11-06 二维码分享

  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.

 
  智能压力变送器压力偏高故障:
 
  Intelligent pressure transmitter pressure is too high fault:
 
  1、现场故障:在对泵出口的压力进行观察之后技术人员发现DCS操作系统所显示的压力值比平常情况下的压力值多,而且在DCS操作系统的显示值进行观察之后可以发现压力值比现场的液晶显示屏超出。
 
  1.Field failure:After observing the pressure at the outlet of the pump,the technician found that the pressure value displayed by the DCS operating system is more than the pressure value under normal conditions,and the pressure value ratio can be found after observing the display value of the DCS operating system The on-site LCD screen exceeded.
 
  2、故障解决:当仪表技术人员赶到现场之后发现智能压力变送器现场表头的液晶显示屏的压力大小与工艺现场的压力大小一样,但是在DCS操作系统中压力大小比平时多出来。通过在现场将正确的电流信号进行输出之后,而且对DCS操作系统的压力值进行测试,发现显示是正确的,这时就可以确定故障是发生在仪器仪表上面了。将智能压力变送器进行更换,然后进行重新检查,发现在DCS操作系统里面压力的显示值变正确。
 
  2.Troubleshooting:When the instrument technicians rushed to the scene,they found that the pressure of the liquid crystal display on the field meter of the smart pressure transmitter was the same as the pressure of the process site,but the pressure in the DCS operating system was more than usual.After outputting the correct current signal on site,and testing the pressure value of the DCS operating system,it is found that the display is correct.At this time,it can be determined that the fault has occurred on the instrument.Replace the smart pressure transmitter,and then re-check it,and found that the pressure display value in the DCS operating system is correct.
