HD53LS… is a series of 2-axis ultrasonic static anemometers for the measurement of:
- Wind speed and direction
- U-V Cartesian components of wind speed
- Wind Gust (only HD53LS.S)
The average of wind speed and direction over a period configurable up to 10 minutes is calculated. Wind speed and direction are determined by measuring the transit time of ultrasonic pulses between two pairs of ultrasonic transducers.
Models with analog output have two equal outputs for wind speed and direction, depending on the model:
- HD53LS.A : 4…20 mA
- HD53LS.V : 0…10 V
- HD53LS.V1 : 0…1 V
- HD53LS.V5 : 0…5 V
HD53LS.S has RS485 MODBUS-RTU output.
All models are equipped with a magnetic compass. Mounting on ∅ 40 mm mast. The electric connection is performed through a M23 19-pole connector situated on the bottom of the instrument.
The low power consumption of the instrument allows installation in remote sites, with power supplied by photovoltaic panel and backup battery. The absence of moving parts minimizes the instrument maintenance.
