一、产品简介   Product Introduction

        CPK-1微差压控制器是一种简易的二位式微差压开关，它利用空气差压在预设定工作点驱动电气执行机构，当预定工作点的差压发生变化时能够自动切换电路。

        CPK-1 microdifferential pressure controller is a simple two position micro differentialpressure switch that uses air differential pressure to drive the electricalactuator at a predetermined working point. When the differential pressure atthe predetermined working point changes, it can automatically switch thecircuit.

        CPK-1微差压控制器可以用来起动或停止电机、风机，打开或关闭风门、排气窗，当差压发生临界变化时，接通报警信号灯、声响报警器等，是一种广泛应用于通风、空调、制冷、环境保护等装置的通用控制器。     

        CPK-1micro differential pressure controller can be used to start or stop motors andfans, open or close air doors and exhaust windows, and turn on alarm signallights, audible alarms, etc. when there is a critical change in differentialpressure. It is a universal controller widely used in ventilation, airconditioning, refrigeration, environmental protection and other devices.
