FQA:
1. What is a pressure sensor?
A pressure sensor is a device that measures the pressure of gases or liquids. It converts the physical pressure into an electrical signal that can be read and processed by control systems or monitoring equipment.
2. How does a pressure sensor work?
Pressure sensors operate by using different technologies, such as piezoresistive, capacitive, or piezoelectric elements, to detect changes in pressure. When pressure is applied, it causes a change in the physical properties of the sensing element, which is then converted into an electrical signal proportional to the pressure.
3. What are the types of pressure sensors?
Piezoresistive Pressure Sensors: Use the piezoresistive effect in materials like silicon to measure pressure.
Capacitive Pressure Sensors: Measure changes in capacitance caused by the deformation of a diaphragm under pressure.
Piezoelectric Pressure Sensors: Use materials that generate an electrical charge in response to applied mechanical stress.
Optical Pressure Sensors: Utilize light modulation to measure pressure changes.
Resonant Pressure Sensors: Measure pressure by detecting changes in the resonant frequency of a sensing element.
4. What is the difference between absolute, gauge, and differential pressure sensors?
Absolute Pressure Sensors: Measure pressure relative to a perfect vacuum.
Gauge Pressure Sensors: Measure pressure relative to atmospheric pressure.
Differential Pressure Sensors: Measure the difference between two pressure points.
