YE系列膜盒压力表

Theca Case Pressure Gauge

简   介

      膜盒压力表采用膜盒作为测压力敏感元件。测量对铜合金不起腐蚀作用、无爆炸危险的气体的微压和真空，广泛应用于锅炉通风、气体管道、燃烧装置及其它类似设备上。

      不锈钢膜盒压力表在普通膜盒压力表的基础上导压系统及外壳均采用了不锈钢材料。应用于耐腐蚀要求较高的工艺流程中对各种气体介质的压力和真空的测量。

      在膜盒压力表的基础上内部填充阻尼液和缓冲装置即成耐震膜盒压力表具有良好的耐震性能；适用于被测介质的压力有强烈脉冲变化或压力冲击和在生产工艺中经常突然卸荷的场合，以及环境震动较大的场所。

      膜盒压力表与相应的电气器件配套使用，即成为电接点膜盒压力表，可达到对被测压力系统实现预先设定的最大或最小压力值的双位自动控制和发信（报警）的目的。

Brief Introduction

      Theca box pressure gauges are used to measure micro pressure and negative pressure of gas that has no danger of explosion and does not erode alloy.       Adopting theca box as sense organ, the gauges are  widely applied to boiler ventilating, gas pipeline, burning device and other similar devices.

      Based on common theca box pressure gauges, stainless theca box pressure gauges introduce stainless material uesd in pressure leading system and crust. The gauges are not only suitable for measuring micro pressure and negative pressure of various gas medium in craftwork flow, which require higher performance of corrosion resistance, but also can be applied to boiler ventilating, gas pipeline, burning device and other similar devices.

构成示意图

结构原理  Structure

      仪表由导压系统（包括接头、膜盒等）、传动机构、指示装置、和外壳等组成（电接点膜盒压力表还包括磁助电接点装置、调节装置及航空插头等）。

      当被测介质作用于膜盒时，其管端产生相应的弹性变形——位移，经传动机构放大后，由指示装置在度盘上把被测压力指示出来。

      电接点膜盒压力表在指示装置将被测压力显示在仪表度盘上的同时，指针带动电接点装置的活动触点与设定指针上的触头（上限或下限）相接触的瞬时，控制系统接通或断开电路，以达到自动控制和发信报警的目的。

      The meter is composed of pressure leading system (including joint and theca box, etc), driving framework, indicating device and crust.(electric contact theca box dressart meter in dude,magnetism of electric conacd)

      When theca box is operated by measured medium, its end will produce elasticity distortiondisplacement. The displacement is enlarged by driving machine, and measured pressure value will be shown up by indicating device on meter dial.

When indicating device installed at electric contact theca box pressure meter shows the measured pressure value on meter dial, the pointer will simultaneously drive active contactor of electric contact device to meet the contactor (upper limit or lower limit) installed at the pointer. Thus control system will switch on or cut off circuit, and both aims of autocontrol and signal sending are all achieved
