WTS-200 seriesDuct Air Velocity Transmitter
High-precision wind speed measurement unit, low starting wind speed and sensitive response
WTS-200 series wind speed transmitter, the shell is made of high temperature resistant and anti-corrosion material. The transmitter is based on the principle of heat dissipation tube, which requires very little air. Even in harsh environments, the performance is stable and reliable. Compared with traditional vane-type wind speed sensors, it can achieve better low-pressure section repeatability and faster accuracy. It has accurate measurement and accuracy of small air volume and wide range ratio. The detection data is accurately calibrated across the full range through the internal microcontroller. Both linear compensation and temperature compensation are realized digitally, so the accuracy and resolution are high; there is no zero point drift and the long-term stability is excellent, making it more cost-effective and more convenient to use. In addition, this series of transmitters can withstand high instantaneous wind speeds and require directional installation.
