| YJTZ型電阻遠(yuǎn)傳壓力表
YJTZ Series Resistance Remote Transmitting Pressure Meter 簡介 遠(yuǎn)傳壓力表適用于測量對鋼及銅合金不起腐蝕作用的流體，氣體和蒸汽的壓力。電阻信號輸出傳至二次儀表上，可以實現(xiàn)現(xiàn)場就地指示壓力以便于現(xiàn)場工藝檢查，還可以實現(xiàn)遠(yuǎn)距離集中控制和調(diào)節(jié)。 不銹鋼的導(dǎo)壓系統(tǒng)及外殼均采用了不銹鋼材料，有較強的耐腐蝕性能，適用于對耐蝕性能有較高要求的場合。 在不銹鋼內(nèi)充灌阻尼液及加裝緩沖裝置，成為不銹鋼耐震。適用于工作環(huán)境有較強震動的場合。 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 fieldfacilitate field technological testing, even to realize concentrated remote controladjustment. The pressure conducting systemits outer housing for stainless steel resistance remote transmitting pressure meter is made of stainless steel, with stronger capacity of corrosion resistance,applicable to such occasions with higher requirements for capacity of corrosion resistance. To fill damping liquidadd 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. 主要技術(shù)參數(shù) - 精確度：1.6級

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. 外形尺寸 External dimension 電阻式遠(yuǎn)傳壓力表配置XCZ-104型二次儀表接線方法 Resistance remote transmitting pressure meter if configured with XCZ-104 type secondary instrument wiring method. 與其他數(shù)顯二次儀表配接時，請按二次儀表說明書的接線圖配接。 For connection with other digital-displaying secondary instrument, please follow the wiring drawing in the instruction book for secondary instrument. 訂貨須知 Ordering instructions 訂貨時須注明：型號、名稱、精確度、測量范圍。如特殊要求，請注明技術(shù)要求。 Ordering instructions: types, names, accuracy grades,measuring ranges .must be clearly noted.
