Overview

1、主要用途与适用范围

1. Main purpose and scope of application

DK系列压力控制器（以下简称控制器）用于石油、化工、冶金、电力、制糖、制药等自动化控制系统中，在系统中作连锁保护器的作用。其中金属波纹管式控制器用于以上各种腐蚀性气体和液体介质，橡胶膜片式控制器用于中性气体和液体介质。

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

介质通过压力接口进入传感器，传感器内设弹性元件，它根据介质压力的变化发生相应位移。传感器则将带动控制器内部传动机构将作用力传到微动开关触点上。在此作用力下微动开关触点相应产生位移，当位移量超过触点行程时，微动开关发生通断动作。

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.
