精密壓力表 YB150A 白云 精密壓力表
產品概述
YB150A精密壓力表是上海自動化儀表四廠生產的白云牌高精度測量儀表,專為工業校驗和精密壓力測量設計。該儀表采用優質彈簧管作為核心測量元件,通過特殊工藝處理確保性能穩定可靠,適用于對銅合金及合金結構鋼無腐蝕性、非結晶、非凝固介質的壓力測量。其鏡面環設計(A型)顯著提升讀數清晰度,外形美觀且實用,廣泛應用于石油、化工、制藥、食品等行業的生產流程及實驗室環境。139
結構與工作原理
儀表由測壓系統、傳動機構、指示裝置和外殼組成。當被測介質壓力作用于彈簧管時,其自由端產生彈性變形位移,通過拉桿帶動齒輪傳動機構放大,最終由指針在分度盤上精確指示壓力值。外殼部分采用密封設計并配備檢封裝置,有效防止機械損傷和污物侵入,確保長期使用的可靠性。鏡面環(A型)和調零裝置(B型)進一步優化了操作便捷性。1718
技術特點
YB150A精密壓力表具有0.4級精度,環境適應性強,可在5~40℃、濕度≤80%的條件下穩定工作。溫度附加誤差為0.4%/10℃,確保在偏離標準溫度(20±3℃)時仍保持較高準確性。儀表提供多種量程選擇(如0~0.1MPa至0~60MPa),重量輕便(A型1kg),便于現場安裝與攜帶。其耐腐蝕材質選項(如不銹鋼)擴展了在特殊介質環境中的應用范圍。61423
應用場景
該儀表主要用于校驗普通工業壓力表,同時適用于工藝現場的高精度壓力監測,如氣體、液體介質的非腐蝕性壓力測量。在石油管道、化工反應釜、制藥設備及食品加工等領域表現優異,兼顧實驗室科研需求。鏡面環設計尤其適合光線復雜環境下的精準讀數。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.
