Overview

1、主要用途與適用范圍

1. Main purpose and scope of application

DK系列壓力控制器（以下簡稱控制器）用于石油、化工、冶金、電力、制糖、制藥等自動化控制系統中，在系統中作連鎖保護器的作用。其中金屬波紋管式控制器用于以上各種腐蝕性氣體和液體介質，橡膠膜片式控制器用于中性氣體和液體介質。

The DK Series pressure controller （hereinafter referred to as ‘the Controller’） are used for the petroleum, chemical, metallurgy, electricity, sugar, pharmaceutical and other automated control system, acting as a chain protector in the system. Among them, the metal bellows-type controller is used for more than a variety of corrosive gases and liquids, and the rubber diaphragm controller for neutral gases and liquids.

3、工作原理

3. Working principle

介質通過壓力接口進入傳感器，傳感器內設彈性元件，它根據介質壓力的變化發生相應位移。傳感器則將帶動控制器內部傳動機構將作用力傳到微動開關觸點上。在此作用力下微動開關觸點相應產生位移，當位移量超過觸點行程時，微動開關發生通斷動作。

Medium come into the sensor via the pressure interface. The sensor is set with elastic elements inside, and its corresponding displacement depends on the pressure changes of medium. The sensor drives the transmission mechanism inside the controller, which brings the force to the contacts on the micro-switch. In this force, the corresponding displacement occurs to the micro-switch contacts. When the displacement exceeds the contact trip, micro switch will have on-off action.
