摘　　要：介质压力是电力生产行业中一种重要的热工参数,处于热工参数检测与控制系统最前端的感测技术的发展,自然倍受电力行业的关注。本文介绍了电力行业中正在应用的几种压力(P)或差压(△P)检测技术,对各自的优缺点做了介绍,并针对自动控制要求的不断提高和使用中仍存在的问题,阐述了压力感测技术发展的趋势。Pressure is one of the most important elements in Instrumentation and control system. Of course,'the sensor, which is at the bottom of the control system, has been attracting attention of power plant industry. Many kinds of pressure sensor techniques being used in power plant at present are introduced in the paper, including their respective advantages and shortcomi ngs. In the end, this paper points out several problems in practice using and illustrates the general trend of pressure transducer in the future to meet the need of auto-control system's high level.
