The YD321 is a digital wind pressure transmitter designed for precise measurement of low differential pressures and air velocity. It features a built-in LCD display for real-time data reading on-site. This instrument is commonly used in HVAC systems, cleanrooms, and environmental monitoring applications where accurate pressure measurement is crucial. It converts the measured pressure into standard electrical signals ( 4-20mA or 0-10V) for transmission to control systems or data acquisition devices.

High Accuracy: Offers reliable and precise measurements for effective system monitoring and control.
Robust Enclosure: The NEMA 4X (IP66) rating ensures protection against water ingress and dust, suitable for demanding environments.
Flexible Outputs: Available with standard analog outputs (4-20mA or 0-10V) for easy integration into existing control systems.
Adjustable Response Time: Allows damping of signal fluctuations to match specific application requirements.
Compact and Durable Design: Designed for easy installation and long-term stability in industrial settings.
The YD321 is ideal for various applications requiring accurate wind pressure or low differential pressure measurement:
HVAC Systems: Monitoring air filter clogging (pressure drop across filters), measuring duct pressures, and controlling fan speeds.
Cleanrooms: Ensuring and maintaining proper pressure differentials between zones to prevent contamination.
Environmental Monitoring: Measuring air flow and pressure in various industrial processes.
Energy Management Systems: Providing data for optimizing building ventilation and reducing energy consumption.
