Absolute Pressure Sensors for Stable, Reference‑Free Measurement
Absolute Pressure Sensors measure pressure relative to a sealed vacuum reference, providing consistent readings regardless of changes in atmospheric pressure. These sensors are ideal for sealed systems, leak detection, altitude‑dependent measurements, and scientific or industrial applications where accuracy and stability are critical. Setra’s absolute pressure sensors are engineered for low drift, high repeatability, and dependable performance in demanding environments. With multiple pressure ranges and output options, they support OEM designs and industrial systems that require precise pressure control over time.
Vacuum‑Referenced Pressure Sensors Designed for Accuracy, Consistency, and Long‑Term Reliability
Absolute pressure sensors provide accurate pressure measurements referenced to a perfect vacuum, making them ideal for barometric, aerospace, industrial, and scientific applications where atmospheric pressure variation cannot affect performance.
Absolute vs. Relative Pressure Sensors
The key difference between absolute and relative pressure sensors is the reference point used for measurement:
- Absolute pressure sensors measure pressure relative to a perfect vacuum, producing stable, fully positive readings that are unaffected by atmospheric changes.
- Relative (gauge) pressure sensors measure pressure relative to the surrounding atmospheric pressure, which can vary with altitude and weather conditions.
