下面是艾默生公司技术人员现场演示的翻译文档.
 

today we are going to demonstrate the power of our predictive intelligence from our plant web 

今天我们将使用Rosemont 30501S压力变送器
 

technology using the Rosemont 30501s pressure transmit 

展示设备的智能预测功能
 

the 3051 s is a highly accurate device that's used to measure pressure DP level and DP flow 

3051S是用来测量差压液位和流量的高精度仪表
 

now using the advanced diagnostics available with the 3051s 

现在我们使用3051s来演示一下
 

we can also detect problems in the process such as a plug impulse line 

我们可以检测取压管道堵塞等问题
 

as you may know impulse lines can plug do the dirty process or freezing of the line 

当工艺介质粘稠或脏污的时候，取压管会堵住
 

when this happens the transmitter is unable to respond to process changes 

当取压管堵住后压力变送器无法及时采集管道中的数据
 

ａnd this will result in misleading pressure measurements 

压力变送器会显示一个错误的数据
 

unfortunately the user does not know when a line has become plugged 

而且我们并不知道取压管发生了堵塞
 

this is because the pressure in the line gets trapped 

因为压力没有传感过来
 

ａnd the transmitter will continue to provide the same measurement as before the plug

压力变送器会一直显示同一个值
 

this misleading measurement will not be discovered for some time 

有时候并不会发现这些错误
 

ａnd by then the plug impulse line may have affected the quality of your process and your product 

会导致生产受到影响
 

to illustrate this plug line issue one will slowly close this valve 

为了模拟取压管的堵塞
 

on impulse line leading to the 3051s 

我们缓慢关闭压力变送器
 

if an impulse line becomes plugged technicians should be aware of this

当取压管堵塞了会有诊断技术检测到
 

The plant web alert can be displayed on the workstations

在操作站上会有报警
 

 that technicians are using to monitor the field devices

这项技术用于监测现场智能设备
 

 as you can tell the plant web alert is flashing on the alarm banner 

操作员站画面报警一栏上面
 

notifying us of the abnormal situation 

会有闪烁提醒我们
 

click on the alarm banner to open up the faceplate to investigate further 

点击报警一栏
 

you can click on the AMS device manager icon 

然后点击AMS的按钮
 

as you can see in addition to just measuring pressure 

除了能够显示压力值后
 

the 3051 s is also measuring the amount of processed variability 

还可以显示压力数值的变化趋势
 

in this case here the process variability decreased which allowed us to trigger an alert 

在上述情况下，压力下降曲线异常
 

that told us it deviated too much from the baseline

AMS智能设备管理系统会提示系统发生报警
 

in traditional practice without these advanced Diagnostics 

如果没有这些的诊断措施
 

we would not have known about the plugged impulse line 

我们不会知道取压管堵塞了
 

by being able to detect the plug line we can take proactive measures to resolve the issue 

DCS上检测到这个故障后
 

before affects the quality of the process 

可以及时处理，防止产生事故
