THIES CLIMA ULTRASONIC ANEMOMETER 2D 4.3820.30.340

ULTRASONIC ANEMOMETER 2D
485/422, FD; VDT, 96 N81PT EK
Text
THE ULTRASONIC ANEMOMETER SERVES FOR THE
ACQUISITION OF THE HORIZONTAL COMPONENTS
OF WIND VELOCITY AND WIND DIRECTION.
AND THE ACOUSTICALL VIRTUAL TEMPERATURE.
THE MEASURED VALUES ARE DELIVERED
IN DIGITAL AND ANALOG FORM.
THE ACOUSTIC MEASURING PRINCIPLE
ALLOWS THE HIGH PRECISION
MEASUREMENT OF RUNNING VARIABLE
DIMENSIONS AND AN INERTIA-FREE
PEAK VALUE ACQUISITION.
BY THE CONTACTLESS MEASURING
METHOD THE INSTRUMENT WORKS
WEAR-FREE.
THE INTEGRATED HIGHLY-DEVELOPED
PTC  HEATING ALLOWES
A DISTURBANCE-FREE WINTER OPERATION
EVEN IN EXTREM ENVIRONMENTS.
