EJX118B無線遠程隔膜密封差壓變送器

無線隔膜密封用於防止製程介質直接進入差壓和壓力變送器的壓力傳感組件,使用充滿液體的毛細管將其連接至變送器。

EJX118B無線隔膜密封差壓變送器和EJX438B無線隔膜密封表壓變送器可用於測量液體、氣體或蒸氣的流量以及液位、密度和壓力。

EJX118B和EJX438B通製無線訊號傳輸製程變量以及設定參數。變送器使用內定電池,因為不需要硬件布線可以大幅降低安裝成本。該通訊協議兼容ISA100.11a協議規格。

摘要:

The use of wireless technology in industrial automation systems offers a number of potential benefits, from the obvious cost reduction brought about by the elimination of wiring to the availability of better plant information, improved productivity and better asset management. However, its practical implementation faces a number of challenges: not least the present lack of a universally agreed standard. This article looks at some of these challenges and presents the approach being taken by Yokogawa.

摘要:

In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.

摘要:

The innovation of wireless technology increases the use of wireless communication in the industry. The introduction of wireless communication to plants, however, requires strict features such as robustness, real-time responsiveness, and low power consumption. This has restricted the use of wireless communication to limited applications such as data logging and device status monitoring that does not require strict real-time responsiveness and data arrival reliability in communication.
