This air velocity sensor is a device used to measure the wind speed in the pipe. The air velocity sensor operates on the hot-wire anemometer principle. Using a self-developed high-precision wind speed measurement unit, it is sensitive and can quickly and accurately measure small air flows, with good stability, small drift, and high accuracy.

The duct type wind speed sensor can calculate the real-time air volume value according to the cross-sectional area of the pipe set to be measured. It is easy to install on-site, and the product adopts an anti-interference circuit design inside, which can withstand various strong electromagnetic interferences such as on-site inverters. The transmitter adopts imported screw-free terminal wiring, which is more convenient to use. There are two options of FS-*-9TH(air velocity sensor) and FS-*-9TH-OLED(air velocity sensor with display).

Air velocity sensor features

1. High-precision wind speed measurement unit, with low start-up wind speed and sensitive response, which can be used in harsh environments such as ventilation ducts and oil fume ducts
2. Adopting the full-scale secondary calibration method independently developed by the company, with good linearity and high accuracy
3. Open-hole flange installation, using high-quality silicone sealing ring, small air leakage, durable
4. Multiple wind speed ranges such as 0~20m/s, 0~30m/s, 0~10m/s, 0~15m/s, etc. can be dialed and set and can be freely changed on-site, and other ranges can also be customized
5. The wiring terminal adopts imported screw-free terminals, no tools are needed, just one press and one plug can be connected
6. Use special EMC anti-interference devices, which can withstand various strong electromagnetic interferences such as on-site inverters
7. DC10～30V wide voltage range power supply
8. with wind speed marking direction, easy to install on-site
