Future development of pressure transmitters
2011-8-22 9:09:14

      成熟的市场 中,在 市场驱动力 使 压力变送器 的性能 不断改善, 尤其 是比较新的高性能变送器, 它的 精度 可靠性 长期漂移和过压保护能力 越来越好。 In the constantly developing and mature market , the performance of pressure transmitters is continuously improved under the new market driving force , especially the newer high-performance transmitters, which have accuracy , reliability , long-term drift and overpressure. Protection is getting better. 新的市场驱动力 因此 影响用户对现有变送器进行更新或者升级的因素 :(1) 现场仪表的管理 (2) 在线分析以及一些应用解决方案中的需要。 Because of the new market driving force , the factors that affect users to update or upgrade existing transmitters are : (1) management of field instruments (2) on- line analysis and the needs in some application solutions.

      可靠性 精度 长期漂移 过压保护能力等压力变送器的性能 方面 不断在得到改善, 且越来越好。 The performance of pressure transmitters such as reliability , accuracy , long-term drift , and over-voltage protection capabilities will continue to improve and become better and better. 一些高性能的新版本 方面 ,更是如此。 This is especially true for some high-performance new versions . 新一级的高性能变送器陆续出现 的时机, ARC高级分析家、研究报告的主要撰写人PaulaHollywood 对这些高性能变送器的定义是:精度高于±0 . 05%以上的产品 ,同时 她还指出,对 最终 用户而言,变送器不断提高的可靠性还意味着更少的维护成本和过程 运行时间。 At the time when new levels of high-performance transmitters appeared , Paula Hollywood , an ARC senior analyst and the main author of the research report , defined these high-performance transmitters as: products with accuracy greater than ± 0.05 % At the same time, she also pointed out that for the end user, the increasing reliability of the transmitter also means less maintenance costs and process uptime.  

压力传感器 变送器之间传统的差异越来越模糊 ,所以 人们从外观上已经不能够区分它们 它们的价格已经具有 可比性。 Because the traditional differences between pressure sensors and transmitters are becoming increasingly blurred , people are no longer able to distinguish them from the outside , and their prices are already comparable. 随着过程工业向现场总线技术转移 实际 具有模拟输出或者电压输出的厚膜电路型仪表结构将受到 越来越多企业的 欢迎。 ARC predicts that as the process industry moves to fieldbus technology , in practice , thick-film circuit-type instrument structures with analog or voltage outputs will be welcomed by more and more companies . 可以 就地显示和编程接口都嵌入在数字通讯协议中, 可以 彻底地降低封装成本和售价。 Its advantage is that the in-situ display and programming interface are embedded in the digital communication protocol, which can completely reduce the packaging cost and price. 比较 小, 所以 它们 安装在以前的变送器无法安装 的地方 ,比如 汽车里或者医疗设备中 Because of their small size , these transmitters can be installed in places where previous transmitters could not be installed , such as in cars or medical equipment .
