3. Technical specifications
(continuation)
The Davis compatible ultrasonic wind sensor
incorporates 12m of cable between the wind sensor
and the box.
50cm of cable terminated in RJ-11 comes out of the
box.
The wind sensor 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 transductors calculates the signal delay
and gets information about both, wind direction and
wind speed.
The wind sensor has lateral and inferior female thread. It can be mounted either on a plate (inferior
screws) or on a tube (lateral screws).

Inside the box there are two connectors, one where
is connected the wind sensor and other where is
connected the cable for the Davis Station.
Pole mount up to 52 mm

3. Technical specifications
(continuation)
Wind sensor is engineered to be a robust device
with minimal downtime. This new shape has been
designed for optimum water spillage which implies
lower probability of ice formation. Frost might
affect measurements if it blocks the wave path.
The box has IP68 rating (outdoors & underwater).
The input wires are protected by Transient Voltage
Suppression (TVS) diodes. Also, the instrument
body is built in Polyamide.
Every single unit is automatically calibrated on a
wind tunnel. A Q/C report for both module and
angle is generated and kept in our files. Standard
deviation is checked to warranty that each unit has
been calibrated to the highest standards.
4. Installation
The installation of Davis Compatible Ultrasonic
wind sensor is very easy.
When you receive the Davis compatible ultrasonic
wind sensor, you have to put the included batteries
inside the box.
Remove the screws to open the box and insert them
in the battery holder in the correct position, after
that close the box with the screws.

5. General information
5.1 General recommendations
As described previously is important to understand
that the unit can be mounted directly on a pole or
using a flat bracket. In either case make sure the
north mark is perfectly aligned.
Then install the sensor in a location free from wind
perturbation.
Other important aspects
· Do not try to modify by any case the unit.
· Avoid touching the transducers
· Do not modify/customizethe surfaceof the unit.
If you have any questions or doubts, please contact
directly with us. We will be glad to assist you in
any time.
5.2 Maintenance and repair
Thanks to the mechanical simplicity the ultrasonic
does not require mechanical maintenance.
Transducers must be kept clean and aligned.
Impacts or incorrect impulsive handling may lead to
transducers misalignment.
The space in between the transducers and its
reflection surface must be empty and clean. Dust,
frost, water, etc… will make the unit stop
working. Rinse with fresh water and let it dry.
The batteries have a duration of about three years,
after this time they must be replaced.
5.3 Warranty

instruct ions of use, repair or maintenance without
written authorization. Every Calypso product offers

damages arising out of:
- Exposition of the Ultrasonic at temperatures out of
the range stated above.
- Transducers misalignment or damage duet to
external impact.
- Geometry changes on the flow channel due to
external actions.
- Use inappropriate voltages.
- Do not install the Davis compatible ultrasonic wind
sensor as stated above which causes damage on
the ultrasonic.
