Industrial HVAC Thermal Anemometer Airflow Sensor: Model KY0012B is engineered for high-precision air velocity monitoring and volumetric energy calculations across central HVAC ventilation ducts, variable air volume (VAV) systems, and air handling units (AHU). Incorporating a high-performance thermal wind speed sensing element imported from Germany, it delivers real-time velocity measurement up to 20 m/s with 0.1 m/s resolution, integrated temperature compensation, and stable RS-485 Modbus or analog signal transmission.

Note: Performance results were obtained under controlled laboratory conditions. Actual performance may vary depending on test conditions, airflow turbulence, duct geometry, and installation environment. Test reports are available upon request.
Engineering Highlights
01. German-Imported Thermal Core
Utilizes a high-precision thermal anemometry sensing chip engineered in Germany, delivering sensitive low-speed response and zero mechanical wear.
02. Active Temperature Compensation
Built-in internal calibration algorithm compensates for ambient duct temperature shifts between -10°C and 50°C to maintain consistent measurement accuracy.
03. Versatile Building Automation Signals
Supports digital RS-485 Modbus networking for centralized BMS building control, along with standard 0~5V DC and 4~20mA industrial analog outputs.
04. Flange Duct Insertion Design
Rugged stainless steel probe shaft with integrated aerodynamic sampling window and mounting flange for rapid in-duct retrofits and cleanroom ventilation lines.
