YD321 Digital Wind Pressure Transmitter
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.
Technical Parameters
Features & Advantages
Digital LCD Display: Provides clear, real-time local reading of pressure or velocity
values directly at the installation point.
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.
Application Scenarios
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.
