DF601It has an extremely sensitive response to extremely low wind speeds and can accurately measure air velocities close to 0m/s. The sensor outputs standard signals of 4-20mA, 0-5V, or 0-10V under a power supply of 12-28VDC, and the output signal is linear with the wind speed. Adopting an integral hot film wind speed sensor with a glass protective layer on the surface, the sensor probe has good anti vibration, anti pollution, and anti moisture capabilities, and its reliability is far better than traditional hot wire wind speed sensors and other ordinary hot film wind speed sensors. Sensors have multiple installation structures, and different probe structures can be selected according to different application scenarios to easily fix the probe in a reasonable position within the measured airflow field, in order to achieve stable signal output. The precise linear correction circuit design and detailed calibration process enable the DF601 sensor to have good accuracy and consistency.
