What Is a Differential Pressure Sensor?

A differential pressure sensor measures the difference in pressure between two points. It is commonly utilized in systems where monitoring pressure differentials is vital for optimizing performance and ensuring safety.

How Do Differential Pressure Sensors Work?

These sensors function by comparing the pressure levels from two sources. The internal mechanism often involves a diaphragm that deflects based on the pressure difference. This deflection leads to an electrical signal that can be read and interpreted by control systems or monitoring equipment.

Applications of Differential Pressure Sensors

The applications of differential pressure sensors are vast. In the HVAC industry, they help in monitoring airflow and ensuring that systems operate efficiently. Similarly, in medical devices, they can monitor the pressure in respiratory systems to ensure patient safety.
