2-Axial Ultrasonic Anemometer for Very Low Wind Speeds
HD53LS is a 2-axis ultrasonic static anemometer for measuring with high sensitivity:
- Wind speed and direction, U-V Cartesian components of wind speed
- Wind gust (only in version with RS485 MODBUS-RTU output)
The average of wind speed and direction over a period configurable up to 10 minutes is calculated.
Two versions are available (please select when ordering!):
-
HD53LS.A: with two analog outputs (one for wind speed and one for wind direction), factory configurable among 4…20mA (standard), 0…1V, 0…5V, 0…10V (to be specified when ordering).
-
HD53LS.S: with RS485 MODBUS-RTU output.
Equipped with magnetic compass.
Supplied with PC software for configuring the instrument and viewing the real time measurements.
Supplied with M23 movable connector.
Optionally available, ILAC-MRA (ACCREDIA) traceable factory calibration.
Advantages of the HD53LS series:
- The absence of moving parts minimizes maintenance.
- High sensitivity for detecting very low speeds, which are not detectable by traditional methods.
- Fast and easy installation (on ∅40mm mast, optional tripod available).
- The low power of the instrument allows installation in remote sites, with power from solar panel and battery.
- The version with RS485 MODBUS-RTU output allows instrument networking.
Typical applications:
- Weather stations
- Environmental monitoring
- Agriculture
- Sports facility
- Marine and Harbour applications
- Airports
- HVAC
- Construction
- Renewable energy
- Building automation
