PRESSURE SENSORSسه فاز دات کام
Pressure sensors are devices that generate electrical signals with the help of changes in ambient pressure. These sensors are used in many industries and applications. Important applications of pressure sensors include the automotive industry, electrical and electronics industries, robotics, medicine, and measurement and control systems.
Pressure sensors work on several principles, including changes in electrical resistance, changes in light transmission, changes in piezoelectricity, and changes in flexibility. Next, we'll look at some of these principles and different types of سنسور فشار سنسیس:
1. Resistive pressure sensors:
These types of sensors work based on the change in the electrical resistance of the pressed material. The structure of these sensors usually comprises two layers of resistive material between which there is a material under pressure. By applying pressure to the sensor, the pressure material transfers the pressure to the resistance layers and the resistance of the sensor changes. This change in resistance is usually read from an electronic card.
2. Diaphragm pressure sensors:
These types of sensors consist of thin membranes that protect against pressure and detect pressure changes. membrane usually
It's made of a flexible material like silicone and changes shape when the pressure changes. This change in shape is detected by sensors located at the edge of the membrane.
3. Relative pressure sensors:
These types of sensors are used to measure pressure relative to ambient pressure. They measure the pressure difference between the surrounding environment and the target pressure. For example, in the automotive industry, this type of sensor is used to measure the air pressure in tyres.
4. Detector pressure sensors (absolute pressure sensors):
These types of sensors measure pressure relative to vacuum or other reference pressure. These sensors generally work on the piezoelectric principle, which means that a change in pressure on a piezoelectric material generates an electrical signal. Pressure sensors are affected by EES due to their wide applications in various industries. When SEOing content related to pressure sensors, consider the following:
