Description: 1. A Differential Pressure Transmitter for Variable Air Volume (VAV) systems is an essential component that measures the pressure difference between two points in the HVAC (Heating, Ventilation, and Air Conditioning) system to maintain optimal airflow and temperature distribution. 2. Design: These transmitters are designed with precision sensors that accurately measure the differential pressure, providing reliable feedback for controlling VAV systems. They come in various connection sizes (ANSI or DIN) and pressure ranges to cater to diverse applications. 3. Integration: The transmitter can be easily integrated into building automation systems, allowing for real-time monitoring of airflow and differential pressure. This data is crucial for energy efficiency, comfort control, and preventive maintenance in HVAC applications. 4. Unique Features: Some high-end models come with advanced features like self-diagnostics, calibration capabilities, and digital output signals (4-20mA or HART)
