    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.

    Existing reviews of Air Differential Pressure Sensor
    Very stable and worry-free
    We installed these differential pressure sensors on our HVAC ducts to monitor supply pressure. The 0‑10V output feeds the DDC controller with a quick response. The ±100kPa range gives plenty of headroom, and zero drift has been nonexistent in real use. The sealed fittings haven't leaked a bit since installation.
