This Differential Air Pressure Sensor is designed for accurate low-pressure measurement in HVAC systems, clean rooms, air filtration units, laboratories, and industrial ventilation applications. It measures air pressure differences in the range of 0–500 Pa with stable performance and high sensitivity. The sensor provides an analog 0–10V output, making it compatible with PLC, BMS, SCADA, EMS, and other control systems. Powered by a 12–24V DC supply, it ensures reliable long-term operation and easy integration into automation and environmental monitoring setups.
