微壓表
產品概述
微壓表是一種專門用于測量微小壓力變化的精密儀器，適用于氣體或液體的低微壓力監測。其核心部件采用波紋膜盒或特殊傳感器，通過彈性形變原理將壓力信號轉換為機械或數字顯示，具備高靈敏度和穩定性。廣泛應用于鍋爐通風、燃氣設備、醫療呼吸監測、潔凈室壓差控制等領域，尤其適合對銅合金無腐蝕性介質的微壓和負壓測量。產品結構包含測量系統、傳動機構、指示部件和防護外殼，支持垂直安裝并適應-40℃至70℃的工作環境。1314
產品特點
微壓表設計兼顧功能性與耐用性，采用不銹鋼或銅合金材質以增強抗腐蝕性，部分型號配備有機玻璃表盤和防震機芯，確保在振動環境下仍能準確讀數。其工作原理基于波紋膜盒受壓變形，通過齒輪傳動放大位移并驅動指針指示壓力值，部分數顯型號直接顯示實時數據。產品具備調零功能，可手動校準零點偏差，且無需外部電源（機械式）或支持超低功耗供電（數顯式）。典型量程覆蓋±60Pa至±40kPa，分辨率可達1Pa，滿足不同場景的精確測量需求。4516
應用場景
該產品適用于多種工業及民用領域，如燃氣管道終端壓力監測、工業窯爐氣流控制、實驗室通風系統壓差檢測等。在醫療設備中可用于呼吸壓力監測，在環保工程中可測量過濾器阻力。其緊湊設計支持嵌入式或面板安裝，適配3/8英寸螺紋接口，便于快速集成到現有系統中。特殊型號還能耐受高濕度、粉塵環境，長期保持性能穩定。72128
Introduction
The micropressure gauge is a precision instrument designed for measuring minimal pressure fluctuations in gases or liquids. Its core component utilizes a bellows or specialized sensor to convert pressure signals into mechanical or digital readings through elastic deformation principles, ensuring high sensitivity and reliability. Ideal for monitoring low-pressure and vacuum conditions in non-corrosive environments, it finds applications in boiler ventilation, gas pipeline systems, medical respiratory devices, and cleanroom differential pressure control. The structure integrates a measurement system, transmission mechanism, indicator components, and protective casing, with vertical installation compatibility and an operational temperature range of -40℃ to 70℃.1314
Key Features
Combining durability with precision, the micropressure gauge employs stainless steel or brass materials for enhanced corrosion resistance. Selected models feature shock-resistant mechanisms and acrylic dials for clear visibility under harsh conditions. The bellows-driven mechanism amplifies minute displacements via gear trains to display pressure values, while digital variants offer direct numerical readouts. With manual zero-adjustment functionality, it requires no external power (mechanical types) or operates on minimal energy (digital types). Standard ranges span ±60Pa to ±40kPa, with resolutions up to 1Pa, catering to diverse measurement needs.4516
Applications
This product serves multiple industrial and civilian sectors, including terminal pressure monitoring in gas networks, airflow regulation in industrial furnaces, and filtration resistance testing in environmental projects. Medical applications include respiratory pressure tracking, while its compact design supports panel or flush mounting with 3/8-inch threaded connections for seamless system integration. Specialized versions maintain stable performance in high-humidity or dusty environments.72128
