防爆電接點壓力表 YX160B全規格精密壓力表
產品概述
YX160B防爆電接點壓力表是一款專為爆炸性環境設計的精密測量儀表，適用于石油、化工、冶金等工業領域。該產品采用隔爆型結構設計，通過彈性元件彈簧管的機械變形帶動電接點動作，實現壓力參數的現場指示和自動控制功能。表殼采用高強度材料制造，能夠有效阻止內部爆炸能量向外傳播，確保在潛在危險環境中的安全使用。1220
技術特點
該壓力表采用垂直安裝方式，測量范圍覆蓋0-0.16MPa至0-60MPa，以及負壓-0.1-2.4MPa等多個量程規格，精度等級達到1.5級。產品配備上下限緩行接點開關，最高可承受DC220V或AC380V工作電壓，觸頭功率為10VA。環境適應性方面，可在-10℃至50℃溫度范圍和不超過80%的相對濕度條件下穩定工作，且對介質脈動和振動具有良好的抗干擾能力。51114
工作原理
當被測介質壓力作用于彈簧管時，其自由端產生的彈性變形通過齒輪傳動機構放大，轉換為指針的旋轉運動并在刻度盤上精確顯示。同時，指針帶動電接點裝置的觸頭，當壓力達到預設值時觸頭閉合或斷開，從而控制外部電路通斷。這一機械-電氣聯動設計實現了壓力監測、報警信號輸出和自動化控制的綜合功能。61321
結構設計
產品由隔爆外殼、測量系統、電接點組件和出線盒等核心部件構成。外殼采用特殊密封結構，觀察窗采用抗沖擊強度達4J的透明材料，確保在內部發生意外爆炸時能有效抑制能量外泄。調節裝置允許用戶根據需要設定壓力控制點，接線盒提供安全可靠的電氣連接接口。整機重量約為6kg，結構緊湊且安裝便捷。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
