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.

結(jié)構(gòu)原理
本儀表由一個(gè)彈簧管壓力表（為一次儀表）和一個(gè)滑線電阻式發(fā)送器等組成。
一次儀表的作用原理與一般彈簧管壓力表相同。由于電阻發(fā)送器系設(shè)置在齒輪傳動(dòng)機(jī)構(gòu)上，因此當(dāng)齒輪傳動(dòng)機(jī)構(gòu)中的扇形齒輪軸產(chǎn)生偏轉(zhuǎn)時(shí)，電阻發(fā)送器的轉(zhuǎn)臂（電刷）也相應(yīng)的地偏轉(zhuǎn)。由于電刷在電阻器上滑行，使得被測(cè)壓力值的變化變換為電阻值的變化，傳到二次儀表上指示出與一次儀表相應(yīng)的壓力值。
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.
