过去用于测量、显示、记录和控制过程的参数例如压力、温度、流量、液位、负载、速度、距离或角度,它们可以通过过程仪器读出,简单的只要温度计就可以读出,复杂的则需要多变量过程分析仪和控制器。这些年来尽管变化不大,但在未来十年,不断增加的功能将会为过程仪表带来很大改进。这些改进包括立即访问数据,显示和无处不在的网络智能化,先进的网络通信和可靠的安全等等。事实上,这些进步得益于无线技术,移动设备和工业因特网。许多过程传感器在可遇见的未来不会有太大变化。最常 In the past, parameters such as pressure, temperature, flow rate, liquid level, load, speed, distance or angle used for measuring, displaying, recording and controlling processes can be read out by process instruments simply as long as the thermometer can read out, complicated You need multivariable process analyzers and controllers. Although little change has been made over the years, in the next ten years ever-increasing functionality will bring significant improvements to process instrumentation. These improvements include immediate access to data, display and ubiquitous network intelligence, advanced network communications and reliable security and more. In fact, these advances have benefited from wireless technologies, mobile devices and the industrial Internet. Many process sensors do not change much in the foreseeable future. Most often
