双针双管差压表Double bourdon tubes differential pressure gauge
YCS/YCSH
产品简介Product overview
双针双管差压表适用于对两个相同或不同压力，进行测量并可对两个测量压力及二压力差值分别指示。产品分为YCS普通型和YCSH防腐型。YCS普通型适用于对无腐蚀性介质的测量，YCSH防腐型可在具有腐蚀性介质及环境中使用。
仪表由两套各自独立的测量系统和指示装置组成。测量压力通过测压元件的弹性变形，通过两个测压元件(弹簧管)之末端各自产生相应的位移，借助于拉杆传动机构的传动予以放大。由固定于齿轮轴上的红、黑指针将所测值分别指示在度盘上，同时中间小盘显示出二压力之差值。
Double bourdon system differential pressure gauges are designed to measure difference between 2 pressures. 2 models available:YCS General available andYCSHCorrosion-Proof. The YCS type is suitable to measuring the un- corrode medium and the YCSH type could be used in corrode environments.
The instrument has 2 independent measuring systems. The measured pressure deflects the elastic elements, dis- placements then take place to actuate gear mechanisms through linkages to carry 2 pointers traveling over instrument dial, and an auxiliary dial shows the pressure difference.

产品使用说明
盘面的最大刻度值即为最大耐压
建议使用的△(差压值P=P+一P-)为盘面的1/2~1/3为最佳，再小了就不好读示值。△P一般不能小于1/10的全量程。
红针指示为正压压力(输入压力为P+);盘针指示为负压压力(输出压力P-)。盘针上的刻度可以和红针形成夹角a直接读数(从盘针上直接看刻度)，也可以单独用盘针在表盘上的示值与红针在表盘上的示值进行计算得出差压值△P=P+-P-
介质为气体或液体，建议用在室内，使用温度为-20℃~60℃一般最小量程做到0.16MPa，如需0.1MPa，可做到±2.5级安装时带田号接头接输入压力P+;带日接输出压力P-

OPERATING INSTRUCTION
The highest indicated value is the highest pressure permitted.
We advice using the 1/2~1/3 of the range as △P. It is not convenient to read if it is too small. △P should not lower than 1/10 of full scale value.
◆The red pointer shows the plus pressure (the pressure input); the dial pointer shows the minus pressure( the pres- sure output). The value could be saw by the angle a between the red and dial pointers ( see directly on the dial pointer). And we can compute the difference using the pointed values of the red pointer and the dial pointer (△P=P+一P-)
It is suitable to measure gas and liquid medium, suggested in roomin-20℃~60℃.
The general lowest range is 0.16MPa. It is could be made to 2.5% if range is 0.1MPa requested.
While mounting, the 田end should be deployed with pressure input terminal and the 日end should be deployed w- ith pressure output terminal
