防爆电接点压力表 YX160B全规格精密压力表
产品概述
YX160B防爆电接点压力表是一款专为爆炸性环境设计的精密测量仪表,适用于石油、化工、冶金等工业领域。该产品采用隔爆型结构设计,通过弹性元件弹簧管的机械变形带动电接点动作,实现压力参数的现场指示和自动控制功能。表壳采用高强度材料制造,能够有效阻止内部爆炸能量向外传播,确保在潜在危险环境中的安全使用。1220
技术特点
该压力表采用垂直安装方式,测量范围覆盖0-0.16MPa至0-60MPa,以及负压-0.1-2.4MPa等多个量程规格,精度等级达到1.5级。产品配备上下限缓行接点开关,最高可承受DC220V或AC380V工作电压,触头功率为10VA。环境适应性方面,可在-10℃至50℃温度范围和不超过80%的相对湿度条件下稳定工作,且对介质脉动和振动具有良好的抗干扰能力。51114
工作原理
当被测介质压力作用于弹簧管时,其自由端产生的弹性变形通过齿轮传动机构放大,转换为指针的旋转运动并在刻度盘上精确显示。同时,指针带动电接点装置的触头,当压力达到预设值时触头闭合或断开,从而控制外部电路通断。这一机械-电气联动设计实现了压力监测、报警信号输出和自动化控制的综合功能。61321
结构设计
产品由隔爆外壳、测量系统、电接点组件和出线盒等核心部件构成。外壳采用特殊密封结构,观察窗采用抗冲击强度达4J的透明材料,确保在内部发生意外爆炸时能有效抑制能量外泄。调节装置允许用户根据需要设定压力控制点,接线盒提供安全可靠的电气连接接口。整机重量约为6kg,结构紧凑且安装便捷。4922
英文介绍(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
