　　Brief Introduction:

　　The remote transmitting pressure meter is applicable to measure pressure of such liquids, gases or vapors that have no erosive attack on steel or copper alloy. Its resistance signal may be output to the secondary instrument, so as to realize local pressure indicating at field and facilitate field technological testing, even to realize concentrated remote control and adjustment.

　　The pressure conducting system and its outer housing for stainless steel resistance remote transmitting pressure meter is made of stainless steel, with stronger capacity of corrosion resistance, and applicable to such occasions with higher requirements for capacity of corrosion resistance.

　　To fill damping liquid and add shock reducer in stainless steel resistance remote transmitting pressure meter, the stainless steel shock resistance resistance remote transmitting pressure meter is constructed, applicable to occasion with stronger vibration in working environment.

　　结构原理

　　本仪表由一个弹簧管压力表(为一次仪表)和一个滑线电阻式发送器等组成。

　　一次仪表的作用原理与一般弹簧管压力表相同。由于电阻发送器系设置在齿轮传动机构上，因此当齿轮传动机构中的扇形齿轮轴产生偏转时，电阻发送器的转臂(电刷)也相应的地偏转。由于电刷在电阻器上滑行，使得被测压力值的变化变换为电阻值的变化，传到二次仪表上指示出与一次仪表相应的压力值。

　　Structure and principle:

　　This instrument comprises of a pressure meter, a slide resistance transmitter, and so on.

　　The mechanical part of this instrument plays same role with normal pressure meter. Because the resistance transmitter is built in the tooth gear, when deflexion occurs on the axle of the segment gear, the rocking arm (electric brush) of the resistance transmitter deflects accordingly. Due to the slide of electric brush on the resistor, changes of the tested pressure value are transformed into changes of resistance value, which is transmitted to secondary instrument. Corresponding value is displayed accordingly. Meanwhile, primary instrument will also indicate corresponding value.
