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.
