Relative pressure sensors
Relative pressure sensors, also known as gauge pressure sensors measure the pressure of a fluid (liquid or gas) relative to the ambient atmospheric pressure. These sensors provide a pressure reading that reflects the difference between the internal pressure of the system being measured and the external atmospheric pressure surrounding the sensor.
Features of relative pressure sensors:
Reference Point: The reference point for relative pressure sensors is the current atmospheric pressure, which means the sensor measures how much higher or lower the system’s pressure is compared to the atmospheric pressure.
Measurement: The sensor gives a reading that can be positive (indicating pressure above atmospheric pressure) or negative (indicating pressure below atmospheric pressure, often referred to as vacuum pressure).
Applications: Relative pressure sensors are commonly used in applications where the pressure is naturally influenced by atmospheric conditions, such as tire pressure monitoring, fluid level measurement in open tanks, and many industrial processes.
Example: Tire Pressure Monitoring: A relative pressure sensor in a car tire measures the pressure inside the tire relative to the surrounding atmospheric pressure, ensuring that the tire is inflated to the correct level for safe driving.
Relative pressure sensors are widely used in everyday and industrial applications where the pressure of a system needs to be measured in relation to the local atmospheric pressure, providing practical and relevant pressure data for many systems.
