精密压力表 YB150A 白云 精密压力表
产品概述
YB150A精密压力表是上海自动化仪表四厂生产的白云牌高精度测量仪表，专为工业校验和精密压力测量设计。该仪表采用优质弹簧管作为核心测量元件，通过特殊工艺处理确保性能稳定可靠，适用于对铜合金及合金结构钢无腐蚀性、非结晶、非凝固介质的压力测量。其镜面环设计（A型）显著提升读数清晰度，外形美观且实用，广泛应用于石油、化工、制药、食品等行业的生产流程及实验室环境。139
结构与工作原理
仪表由测压系统、传动机构、指示装置和外壳组成。当被测介质压力作用于弹簧管时，其自由端产生弹性变形位移，通过拉杆带动齿轮传动机构放大，最终由指针在分度盘上精确指示压力值。外壳部分采用密封设计并配备检封装置，有效防止机械损伤和污物侵入，确保长期使用的可靠性。镜面环（A型）和调零装置（B型）进一步优化了操作便捷性。1718
技术特点
YB150A精密压力表具有0.4级精度，环境适应性强，可在5～40℃、湿度≤80%的条件下稳定工作。温度附加误差为0.4%/10℃，确保在偏离标准温度（20±3℃）时仍保持较高准确性。仪表提供多种量程选择（如0～0.1MPa至0～60MPa），重量轻便（A型1kg），便于现场安装与携带。其耐腐蚀材质选项（如不锈钢）扩展了在特殊介质环境中的应用范围。61423
应用场景
该仪表主要用于校验普通工业压力表，同时适用于工艺现场的高精度压力监测，如气体、液体介质的非腐蚀性压力测量。在石油管道、化工反应釜、制药设备及食品加工等领域表现优异，兼顾实验室科研需求。镜面环设计尤其适合光线复杂环境下的精准读数。21222
Product Overview
The YB150A precision pressure gauge, manufactured under the Baiyun brand by Shanghai Automation Instrumentation Factory No.4, is designed for industrial calibration and high-accuracy pressure measurement. Its robust construction features a specially treated spring tube as the core component, ensuring stable performance in measuring non-corrosive, non-crystalline media compatible with copper alloys and alloy steels. The mirrored scale ring (Type A) enhances readability, making it ideal for sectors like petroleum, chemical processing, and food production.
Design & Operation
Comprising a pressure measurement system, transmission mechanism, indicator, and sealed housing, the gauge operates via elastic deformation of the spring tube under pressure, which is magnified by gear mechanisms and displayed via a pointer. The housing’s dustproof and impact-resistant design, along with optional zero-adjustment (Type B), ensures durability and user convenience.
Technical Features
With 0.4% accuracy, the YB150A performs reliably in environments of 5–40℃ and ≤80% humidity. Its temperature compensation capability (0.4%/10℃) minimizes deviations under non-standard conditions. Available in multiple ranges (e.g., 0–60MPa) and lightweight (1kg for Type A), it supports flexible field applications. Corrosion-resistant variants extend usability in harsh media.
Applications
Primarily used to calibrate industrial pressure gauges, it also excels in real-time monitoring of gas/liquid pressure in pipelines, reactors, and processing equipment. The mirrored scale is particularly effective in low-light or complex visual environments, ensuring precise readings for quality control and research.
