Chapter 11 ____________________________________________________ Technical Specifications
VAISALA______________________________________________________________________ 177
- When the analog output option is applied, digital communication is not available.
General Conditions
- Due to the measurement frequency used in the sonic transducers, RF interference in the
200 ... 400 kHz range can disturb wind measurement.
- Any temporary element or object, such as snow, ice, or a bird, blocking the measurement path
between the ultrasonic transducer heads can affect the wind measurement accuracy or even
invalidate the output data.
- Extreme operating conditions can alter sensor performance temporarily.
