Ultrasonic transducers (4x)
The Ultrasonic Portable Mini has been designed to avoid
any mechanical parts to maximize reliability and minimize
maintenance.
The transducers communicate between themselves two
by two using ultrasonic range waves. Each couple of trans-
ductors calculate the signal delay and get information
about both, wind direction and wind speed.
Sample rate: 1 Hz

3.7. Protection grade
· IPX8 (10 meters)
The Ultrasonic Portable Mini is been certified by an appro-
ved independent laboratoty as IPX8. In order to get that
IPX8 code certificacion, ULTRASONIC PORTABLE MINI
has successfully passed a 30 minutes water immersion
test at a depth of 10 meters (1bar) with no water ingress.
We have also run more severe tests in house with success-
full results (even though they are not certified).
However, reaching IPx8 30 min-10 m does not yield
warranty of waterproofness at 10 m. The same rationale
applies to swimming watches; a watch needs to be tested
at 30-50 meters depth to be considered water-resistant at
a swimming depth of around 1 meter. For going deeper
than (snorkeling, diving) watches are individually tested up
to 200-500 m.
Several factors might affect Ultrasonic watertightness:
rubber seals and plastics wear and tear, drastic temperatu-
re changes (hot air then cold water), previous impacts,
pressure increase rate (immersion velocity), water density
and temperature, under-water speed and acceleration, ...
This is why we do certify that our Ultrasonic is IPX8 30
min-10 m but we cannot warranty that is waterproof at
10 m.
3.8. Easy mount
· Tripod mount (female thread)
A wide range of accessories can be used with the device.
