Bourdon Tube Capsule Pressure Gauge

Conventional pressure measuring instruments have obvious limitations in micro-pressure and low-pressure industrial scenarios. Standard Bourdon tube pressure gauges lack sufficient sensitivity for tiny pressure changes, unable to accurately display millibar-level gas pressure fluctuations. Electronic pressure transmitters require power supply and signal conversion, with higher costs and failure risks in simple on-site indication applications. Ordinary differential pressure gauges have poor shock resistance and low stability, prone to pointer jitter and data deviation under airflow vibration and pressure fluctuation. Complex electronic sensors also face aging and electromagnetic interference problems in long-term unattended operation. The Bourdon Tube Capsule Pressure Gauge thoroughly solves the above industry pain points. Adopting dual mechanical sensing structure of precision welded capsule diaphragm and high-elasticity Bourdon tube, it converts tiny gas pressure changes into proportional mechanical displacement. The capsule unit captures micro-pressure variations with ultra-high sensitivity, while the Bourdon tube ensures overall structural stability and linear transmission. Through precision gear linkage amplification mechanism, the subtle elastic deflection is accurately converted into pointer rotation, realizing real-time visual pressure reading. Featuring full mechanical design, it requires no power supply, no software calibration and no signal processing, completely avoiding electronic drift and interference errors. With shock-resistant structure, anti-corrosion shell and high repeatability, it maintains stable and accurate indication for long-term cyclic micro-pressure working conditions, being the most cost-effective dedicated solution for industrial low-pressure gas monitoring.

This industrial Bourdon tube capsule pressure gauge supports diversified personalized customization for HVAC engineering, gas pipeline detection, industrial ventilation systems, boiler micro-pressure monitoring and laboratory precision pressure testing projects. Optimized capsule diaphragm sensing structure greatly improves micro-pressure resolution, accurately capturing low-pressure changes that ordinary pressure gauges cannot identify. Classic Bourdon tube elastic sensing technology ensures excellent linearity and mechanical repeatability without zero drift. Fully passive mechanical operation eliminates power supply dependence, adapting to explosion-proof and powerless field environments. Reinforced shockproof and anti-vibration internal structure effectively suppresses pointer jitter caused by airflow impact and pipeline vibration. High-strength anti-corrosion shell and waterproof dial design adapt to humid, dusty and complex industrial sites. High-precision dial calibration achieves clear reading and long-term scale stability. According to project demands, we can customize pressure range, dial size, installation thread, connection type, vacuum/pressure dual-scale and anti-corrosion grade to meet refined low-pressure measurement requirements of different industrial scenarios.
