Understanding Differential Pressure Gauge Bellow Type Mechanics

Bellow type differential pressure gauges utilize flexible metallic bellows to measure pressure differences across systems, offering superior accuracy (±0.5% FS) in challenging environments. These instruments operate within temperature ranges of -40°C to 400°C, withstanding pressures up to 6,000 psi. Unlike diaphragm-based models, bellows provide 30% greater stroke length, enabling precise measurement in viscous fluid applications common in petrochemical and pharmaceutical industries.

Technical Superiority in Measurement Systems

Advanced models feature dual-bellow configurations with temperature compensation, reducing measurement drift to <0.1% per year. Key performance metrics include:

• Repeatability: 0.25% of span
• Hysteresis: ≤0.3% FS
• Response time: <50 ms

Seamless integration with SCADA systems through 4-20 mA or HART protocols enhances process control capabilities.
