Gauge pressure sensor is a sensor that measures the relative pressure, أي. the pressure value relative to atmospheric pressure. A differential pressure sensor is a sensor that measures the pressure difference between two measurement chambers. An absolute pressure transducer is a transducer that measures pressure relative to vacuum or absolute zero.
Submersible pump pressure sensors operate on the principle of electrical signal changes due to pressure changes. Typically, the pressure sensor contains a pressure sensitive element, when the external water pressure acts on the element, it will cause its deformation, which in turn changes the internal resistance or capacitance. This change is converted into an electrical signal, which is processed by a circuit that outputs a signal proportional to the water pressure. The submersible pump reads this signal to adjust its operating status, such as starting, stopping, or regulating the pump speed to adapt to different water depth conditions.
Pressure sensors, as an important component in pump controllers, are responsible for real-time monitoring of pressure changes in the pump system and providing accurate feedback signals to the control system. The application of pressure sensors has been transformed from traditional mechanical monitoring to digitalization and intelligence. It not only plays an important role in real-time monitoring of pumps, energy efficiency optimization, fault warning and so on.
