防爆電接點(diǎn)壓力表 YX160B全規(guī)格精密壓力表
產(chǎn)品概述
YX160B防爆電接點(diǎn)壓力表是一款專為爆炸性環(huán)境設(shè)計的精密測量儀表，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，通過彈性元件彈簧管的機(jī)械變形帶動電接點(diǎn)動作，實(shí)現(xiàn)壓力參數(shù)的現(xiàn)場指示和自動控制功能。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，測量范圍覆蓋0-0.16MPa至0-60MPa，以及負(fù)壓-0.1-2.4MPa等多個量程規(guī)格，精度等級達(dá)到1.5級。產(chǎn)品配備上下限緩行接點(diǎn)開關(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80%的相對濕度條件下穩(wěn)定工作，且對介質(zhì)脈動和振動具有良好的抗干擾能力。51114
工作原理
當(dāng)被測介質(zhì)壓力作用于彈簧管時，其自由端產(chǎn)生的彈性變形通過齒輪傳動機(jī)構(gòu)放大，轉(zhuǎn)換為指針的旋轉(zhuǎn)運(yùn)動并在刻度盤上精確顯示。同時，指針帶動電接點(diǎn)裝置的觸頭，當(dāng)壓力達(dá)到預(yù)設(shè)值時觸頭閉合或斷開，從而控制外部電路通斷。這一機(jī)械-電氣聯(lián)動設(shè)計實(shí)現(xiàn)了壓力監(jiān)測、報警信號輸出和自動化控制的綜合功能。61321
結(jié)構(gòu)設(shè)計
產(chǎn)品由隔爆外殼、測量系統(tǒng)、電接點(diǎn)組件和出線盒等核心部件構(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)生意外爆炸時能有效抑制能量外泄。調(diào)節(jié)裝置允許用戶根據(jù)需要設(shè)定壓力控制點(diǎn)，接線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
