WSA Air Velocity Transmitter

The WSA is a high-accuracy duct type wind speed sensor which can quickly measure the small wind speed. It is stable, high-accurate, and with small drift only. It can calculate the value of the current air volume depending on the measured cross-sectional area of the ducting. This sensor is equipped with EMC anti-interference devices so that it can withstand strong electromagnetic interferences.
Main features:

• Power supply with a wide voltage range of 10~30Vdc; long-distance centralized power supply 
• Analog output for AI template
• RS-485 outputs for the communication of new systems. 
• 4 setting of measuring range: 0~10m/s, 0~15 m/s, 0~20 m/s(default setting), 0~30 m/s. 
• The accuracy of the setting range for 0~10m/s is ±(0.1+2%FS); for 0~15m/s, 0~20m/s, 0~30m/s are ±(0.2+2%FS) m/s
