一、产品简介   Product Introduction

        D501/7D切换差可调、D501/7D切换差不可调、D501/7DK小切换差不可调、D501/7DZ双触点不可调全系列压力控制器采用膜片式传感器。部分规格传感器接液材料不锈钢,可用于腐蚀性介质,也可用于空气、气体、水蒸汽等中性气体和油等液体介质。控制器的设定值可调，调节范围0~2.5MPa。

        D501/7D switching difference isadjustable, the D501/7D switching difference is not adjustable, the D501/7DKsmall switching difference is not adjustable, and the D501/7DZ dual contact isnot adjustable. The entire series of pressure controllers adopts diaphragmsensors. Some specifications of sensors are made of stainless steel, which canbe used for corrosive media, as well as neutral gases such as air, gas, watervapor, and liquid media such as oil. The setting value of the controller isadjustable, with an adjustment range of 0-2.5MPa.
