Absolute Pressure Gauges
Specialised instruments designed to measure pressure relative to a perfect vacuum (zero reference point), rather than relative to atmospheric pressure.
This type of gauge is crucial in applications where precise pressure measurements are required regardless of changes in atmospheric pressure. Absolute pressure gauges measure the total pressure exerted by a fluid (liquid or gas) by referencing a perfect vacuum. This provides readings that are unaffected by variations in atmospheric pressure.
They utilise different sensor types, including capacitive, piezoelectric, and resonant silicon sensors, each suited for specific pressure ranges and applications and are designed to provide accurate readings regardless of environmental conditions, including temperature variations, ensuring reliability in different operational settings.
Used in applications where accurate absolute pressure measurement is critical, such as:
• Vacuum Systems: Critical for monitoring and controlling vacuum pressures in systems such as vacuum pumps and chambers.
• Aerospace: Used in altimeters and barometric pressure measurement for precise altitude determination.
• Semiconductor Manufacturing: Essential for maintaining the precise vacuum conditions needed in semiconductor fabrication processes.
• Chemical Processing: Used in reactions and processes where absolute pressure needs to be precisely controlled and monitored.
• Research and Development: Utilised in experimental setups requiring exact pressure measurements under controlled conditions.
