A pressure sensor is a transducer that converts fluid or gas pressure into an electrical signal (e.g., voltage, current, digital output) for monitoring, control, and safety in industrial, automotive, medical, and aerospace systems. It ensures precise pressure management in real-time, preventing equipment failure and optimizing processes.
Type | Operating Principle & Applications | Pros & Cons |
---|---|---|
Strain Gauge | Measures deformation of a diaphragm via piezoresistive elements. | ✅ Robust, cost-effective ❌ Sensitive to temperature drift |
Capacitive | Detects capacitance changes between diaphragms/electrodes. | ✅ High accuracy, low power ❌ Complex signal conditioning |
Piezoelectric | Generates charge from pressure-induced crystal strain. | ✅ Dynamic pressure sensing ❌ Unsuitable for static pressure |
Optical | Uses fiber Bragg gratings (FBG) to measure wavelength shift. | ✅ EMI-immune, explosive environments ❌ High cost |
MEMS (Micro-Electro-Mechanical) | Miniaturized silicon-based sensors. | ✅ Compact, low-cost, digital output ❌ Limited high-pressure range |
