Common Pressure Sensor Types
Common types of pressure sensors include
Common types of pressure sensors include:
Capacitive Pressure Sensors: Capacitive pressure sensors determine the pressure value by measuring a capacitance that changes depending on the pressure. They are usually created using micromechanical structures.
Piezoelectric Pressure Sensors: Piezoelectric pressure sensors measure the electrical charge or voltage changes produced by piezoelectric materials when they are subjected to pressure. These sensors are often used for high speed or dynamic pressure measurements.
Resistance Based Pressure Sensors: Resistance based pressure sensors are sensors that show changes in resistance value when exposed to pressure. They are created using resistive sensors, also called strain gage or tension gage.
Magnetic Pressure Sensors: Magnetic pressure sensors detect changes in magnetic fields due to pressure. These sensors are made using components that are sensitive to magnetic fields.
Microelectromechanical System (MEMS) Pressure Sensors: MEMS pressure sensors are sensors made on a micro scale and produced using microelectronic technology. Because they have microstructures, they offer small size, low power consumption and cost-effective solutions.
Optical Pressure Sensors: Optical pressure sensors work using pressure-sensitive optical principles. These sensors measure changes in the propagation speed of light, reflection properties or optical properties of optical sensors due to pressure.
These are just some common types of pressure sensors, and other sensors are also available. Sensor selection should be based on measurement requirements, ambient conditions and application area. Each type of sensor has its advantages, disadvantages and suitable uses.
