    Tips: What does a differential pressure sensor do?

    A differential pressure sensor is a device that measures the difference in pressure between two points in a system or across a component. It operates by comparing the pressure at one location to the pressure at another and generates an output signal proportional to the pressure differential. This type of sensor is commonly used in various applications, such as industrial processes, automotive systems, and HVAC (heating, ventilation, and air conditioning) systems.

    The key function of a differential pressure sensor is to monitor and control the flow, level, or pressure of fluids or gases within a system. By measuring the pressure difference, it can provide valuable information about fluid flow rates, filter clogging, or the functioning of valves and pumps. Differential pressure sensors play a crucial role in ensuring the efficiency and safety of many engineering and industrial processes by enabling precise control and monitoring of pressure variances.
