精密壓力表 YB150A 白云 精密壓力表
產(chǎn)品概述
YB150A精密壓力表是上海自動化儀表四廠生產(chǎn)的白云牌高精度測量儀表，專為工業(yè)校驗和精密壓力測量設(shè)計。該儀表采用優(yōu)質(zhì)彈簧管作為核心測量元件，通過特殊工藝處理確保性能穩(wěn)定可靠，適用于對銅合金及合金結(jié)構(gòu)鋼無腐蝕性、非結(jié)晶、非凝固介質(zhì)的壓力測量。其鏡面環(huán)設(shè)計（A型）顯著提升讀數(shù)清晰度，外形美觀且實用，廣泛應(yīng)用于石油、化工、制藥、食品等行業(yè)的生產(chǎn)流程及實驗室環(huán)境。139
結(jié)構(gòu)與工作原理
儀表由測壓系統(tǒng)、傳動機構(gòu)、指示裝置和外殼組成。當被測介質(zhì)壓力作用于彈簧管時，其自由端產(chǎn)生彈性變形位移，通過拉桿帶動齒輪傳動機構(gòu)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(shè)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(huán)（A型）和調(diào)零裝置（B型）進一步優(yōu)化了操作便捷性。1718
技術(shù)特點
YB150A精密壓力表具有0.4級精度，環(huán)境適應(yīng)性強，可在5～40℃、濕度≤80%的條件下穩(wěn)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(xiàn)場安裝與攜帶。其耐腐蝕材質(zhì)選項（如不銹鋼）擴展了在特殊介質(zhì)環(huán)境中的應(yīng)用范圍。61423
應(yīng)用場景
該儀表主要用于校驗普通工業(yè)壓力表，同時適用于工藝現(xiàn)場的高精度壓力監(jiān)測，如氣體、液體介質(zhì)的非腐蝕性壓力測量。在石油管道、化工反應(yīng)釜、制藥設(shè)備及食品加工等領(lǐng)域表現(xiàn)優(yōu)異，兼顧實驗室科研需求。鏡面環(huán)設(shè)計尤其適合光線復(fù)雜環(huán)境下的精準讀數(shù)。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.
