YX160B防爆電接點(diǎn)壓力表是一款專(zhuān)為爆炸性環(huán)境設(shè)計(jì)的精密測(cè)量?jī)x表，適用于石油、化工、冶金等工業(yè)領(lǐng)域。該產(chǎn)品采用隔爆型結(jié)構(gòu)設(shè)計(jì)，通過(guò)彈性元件彈簧管的機(jī)械變形帶動(dòng)電接點(diǎn)動(dòng)作，實(shí)現(xiàn)壓力參數(shù)的現(xiàn)場(chǎng)指示和自動(dòng)控制功能。表殼采用高強(qiáng)度材料制造，能夠有效阻止內(nèi)部爆炸能量向外傳播，確保在潛在危險(xiǎn)環(huán)境中的安全使用。1220
技術(shù)特點(diǎn)
該壓力表采用垂直安裝方式，測(cè)量范圍覆蓋0-0.16MPa至0-60MPa，以及負(fù)壓-0.1-2.4MPa等多個(gè)量程規(guī)格，精度等級(jí)達(dá)到1.5級(jí)。產(chǎn)品配備上下限緩行接點(diǎn)開(kāi)關(guān)，最高可承受DC220V或AC380V工作電壓，觸頭功率為10VA。環(huán)境適應(yīng)性方面，可在-10℃至50℃溫度范圍和不超過(guò)80%的相對(duì)濕度條件下穩(wěn)定工作，且對(duì)介質(zhì)脈動(dòng)和振動(dòng)具有良好的抗干擾能力。51114
工作原理
當(dāng)被測(cè)介質(zhì)壓力作用于彈簧管時(shí)，其自由端產(chǎn)生的彈性變形通過(guò)齒輪傳動(dòng)機(jī)構(gòu)放大，轉(zhuǎn)換為指針的旋轉(zhuǎn)運(yùn)動(dòng)并在刻度盤(pán)上精確顯示。同時(shí)，指針帶動(dòng)電接點(diǎn)裝置的觸頭，當(dāng)壓力達(dá)到預(yù)設(shè)值時(shí)觸頭閉合或斷開(kāi)，從而控制外部電路通斷。這一機(jī)械-電氣聯(lián)動(dòng)設(shè)計(jì)實(shí)現(xiàn)了壓力監(jiān)測(cè)、報(bào)警信號(hào)輸出和自動(dòng)化控制的綜合功能。61321
結(jié)構(gòu)設(shè)計(jì)
產(chǎn)品由隔爆外殼、測(cè)量系統(tǒng)、電接點(diǎn)組件和出線(xiàn)盒等核心部件構(gòu)成。外殼采用特殊密封結(jié)構(gòu)，觀察窗采用抗沖擊強(qiáng)度達(dá)4J的透明材料，確保在內(nèi)部發(fā)生意外爆炸時(shí)能有效抑制能量外泄。調(diào)節(jié)裝置允許用戶(hù)根據(jù)需要設(shè)定壓力控制點(diǎn)，接線(xiàn)盒提供安全可靠的電氣連接接口。整機(jī)重量約為6kg，結(jié)構(gòu)緊湊且安裝便捷。4922
英文介紹（Product Description）
The YX160B explosion-proof pressure gauge with electrical contact is a precision instrument designed for hazardous environments containing potentially explosive mixtures. It features a robust cast aluminum housing with flameproof construction that prevents internal sparks from igniting external atmospheres. The measuring system employs a Bourdon tube mechanism coupled with durable contact points, providing both visual indication and electrical switching functions within one compact device.71825
With 1.5% accuracy class, this gauge offers multiple pressure ranges from vacuum -0.1MPa up to 60MPa positive pressure. The contacts support both AC and DC circuits (max.380V/10VA) for reliable control signaling. All wetted parts utilize corrosion-resistant materials suitable for measuring non-crystallizing liquids and gases. The front window maintains 4J impact resistance while allowing clear reading of the 160mm dial. Field-adjustable setpoints enable flexible configuration for various process control applications.3815
The product s mechanical design ensures stable operation under vibration conditions, with temperature compensation maintaining measurement integrity across -10°C to +50°C. The terminal box incorporates double-sealing technology for cable entry protection. Typical applications include petrochemical plants, pharmaceutical facilities and other industrial processes requiring safe pressure monitoring in classified hazardous areas.121724
Note: The electrical contacts should be connected to appropriately rated control devices to form complete monitoring systems. Proper installation orientation (vertical) and periodic calibration are recommended for optimal performance. The gauge s intrinsically safe design focuses on preventing ignition sources while delivering accurate pressure measurement in demanding operating environments.101619
