How Do Fluid Pressure Sensors Work?

Fluid pressure sensors, also known as pressure transducers or transmitters, are engineered to gauge the pressure of fluids (be it liquid or gas) and turn those measurements into electrical signals.

At the heart of these sensors is a pressure-sensitive part, typically a diaphragm. When the fluid pushes against the sensor, this diaphragm bends or moves slightly. The amount it moves is directly related to the pressure of the fluid. This physical movement of the diaphragm is then transformed into an electrical signal, which can be read and used to monitor or control the pressure of the fluid.
