An
Ordinary pressure gauge, also known as a mechanical pressure gauge or Bourdon tube gauge, is a widely used instrument for measuring and displaying pressure in industrial, commercial, and residential applications. It operates on the principle of mechanical deformation, converting applied pressure into a readable indication on a dial face, without requiring external power sources.
Key Features
Mechanical Operation: Utilizes a Bourdon tube （C-shaped, helical, or spiral） that deforms proportionally to the applied pressure. This deformation is transmitted via a linkage mechanism to a pointer, which moves across a calibrated scale.
Simple and Reliable: Offers instant, direct pressure readings with high accuracy for its class, making it ideal for routine monitoring.
Durable Construction: Typically housed in a robust metal case （e.g., stainless steel or brass） with a glass or polycarbonate window to protect the dial. Wetted parts are often made of corrosion-resistant materials like copper alloy or stainless steel.
Wide Pressure Ranges: Available in various pressure ranges （e.g., vacuum, low pressure, or high pressure） to suit different applications.
Cost-Effective: Provides a budget-friendly solution for basic pressure monitoring needs, with minimal maintenance requirements.
Applications
HVAC Systems: Monitors air and water pressure in boilers, chillers, and pneumatic controls.
Pneumatic and Hydraulic Systems: Checks pressure in compressors, pumps, and cylinders.
Automotive and Aerospace: Tests tire pressure, hydraulic systems, and engine components.
Water Supply Networks: Tracks pressure in pipelines, storage tanks, and irrigation systems.
Advantages
No Power Required: Operates independently, making it suitable for remote or off-grid locations.
Instant Readings: Provides real-time pressure data without delays.
Easy to Install: Can be mounted directly onto pipes, valves, or pressure vessels using standard fittings.
Limitations
Ordinary pressure gauges lack digital outputs, remote monitoring capabilities, or advanced features like data logging. They are also susceptible to mechanical wear over time, requiring periodic recalibration.
In summary, the ordinary
PRESSURE GAUGE remains a staple in industries where straightforward, reliable pressure measurement is essential. Its simplicity, affordability, and independence from external power make it a trusted choice for countless applications.
