ULTRASONIC ANEMOMETER 2D
485/422/HD/96N81.4-20mA,Pt,EK
THE ULTRASONIC ANEMOMETER 2D RECORDS THE HORIZONTAL COMPONENTS
OF THE WIND SPEED AND THE WIND DIRECTION AS WELL AS THE ACOUSTIC
VIRTUAL TEMPERATURE. THE MEASUREMENT VALUES
ARE OUTPUT DIGITALLY AND ANALOGUE.
THE ACOUSTIC MEASUREMENT PRINCIPLE
ALLOWS MEASUREMENT OF RAPIDLY
CHANGING VALUES AND THE DETECTION OF GUSTS AND PEAK VALUES WITHOUT INERTIA LOSSES AND WITH THE HIGHEST PRECISION.
THE NON-CONTACT MEASUREMENT METHODS MAKES THE DEVICE
WEAR-FREE.
AN INTEGRATED PTC HEATER AVOIDS
DISTURBANCES IN WINTER OPERATION
EVEN UNDER EXTREME CONDITIONS.
