Description
Due to environmental quality management and energy management, we've developed WSA, wind speed sensors which can be applied on ventilation systems, air conditioning, and negative pressure rooms. 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. Also, it can caculate the value of the current air volume depending on the measured cross-sectional area of the ducting. Ducting installation and screwless terminals help the users work more easily. Besides, the sensor is equipped with EMC anti-interference devices so that it can withstand strong electromagnetic interferences.
Features
■ High-precision wind speed measurement unit with low start-up wind speed and sensitive response that can be used in harsh environments with ventilation ducts and oil fume ducts
■ High accuracy full-scale secondary calibration method demonstrates good linearity
■ Open-hole flange construction using high-quality and durable silicone sealing ring to reduce air leakage
■ Calculate the value of the current air volume by setting measured cross-sectional area of the ducting
■ Using screw-free terminals. No tools are needed for the wiring terminals, just one press and one plug
■ Using special EMC anti-interference devices which can withstand strong electromagnetic interferences
■ Wind speed mark on the sensor for easy installation
■ Power supply with a wide voltage range of 10~30Vdc; long-distance centralized power supply
■ Equipped with 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. Adjusted by dip switches
■ 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
■ Able to set the output signals (4~20mA, 0~5V, and 0~10V)
■ Able to choose to go with/without OLED
Applications
■ New building construction with ventilation system
■ Negative-pressure rooms in hospital
■ Laboratory
■ HVAC
■ Vent discharge ducts
