Understanding Pressure Sensors
A Pressure Sensor works by detecting the force of a fluid (liquid or gas) and transforming it into a measurable signal. Depending on the type, it can measure absolute pressure (relative to vacuum), gauge pressure (relative to atmospheric pressure), or differential pressure (difference between two points).
Common Types of Pressure Sensors
- Piezoelectric Sensors: Generate voltage when subjected to pressure.
- Capacitive Sensors: Measure pressure by detecting changes in capacitance.
- Strain Gauge Sensors: Detect deformation caused by pressure.
- Optical Sensors: Use light-based methods to detect pressure changes.
These sensors can be found in a wide range of sizes, accuracies, and operating ranges to suit specific industrial and everyday applications.
