1. What Are Pressure Sensors?
Pressure sensors measure the pressure of a medium and convert it into an electrical signal. Depending on the application, these sensors can detect relative, absolute, or differential pressure. Thus, they offer versatility in different settings.
2. How Do Pressure Sensors Work?
Pressure sensors generally consist of a sensing element made from piezoelectric materials, strain gauges, or capacitive technology. Let’s examine how each type operates:
- Piezoelectric Sensors: These sensors utilize piezoelectric materials that generate an electrical voltage when subjected to pressure. The voltage produced is then measured to determine the applied pressure.
- Strain Gauge Sensors: These sensors feature a measuring element connected to an elastic component. When pressure is applied, the elastic element deforms. Consequently, the strain gauge measures this deformation.
- Capacitive Sensors: These sensors include two plates that form a capacitor. When pressure is applied, the distance between the plates changes, which in turn alters the capacitance. The sensor then converts this change in capacitance into an electrical signal.
3. Calibration of Pressure Sensors
Calibration is essential for ensuring that pressure sensors provide accurate readings. This process involves adjusting the sensor with known pressure standards, which guarantees consistent and reliable results.
