Electrical connections
INDUSTRY wind sensors are connected to a data measuring system via the open cable end. The sensors have a cable
plug connection to the 12 m cable.
The connecting cable is suitably led along the mast between the data evaluation device (indicating instrument
or data acquisition system) and the sensor. The cable must be fastened using appropriate cable ties (their length
depends on the mast diameter).
Tip: Lead the cable in a wide curve from the mast to the bottom of the casing so that you can later easily
dismount the cable.
Please make sure the cable is protected from humidity on the side of the data processing system. Generally, Pg
sockets that use a rubber joint to prevent humidity from penetrating into the terminal box of the data processing
system provide sufficient protection.
Example: Cable run by an EMC fair Pg-socket
Alternatively the lead can be laid also completely in the pipes of a mast, if the mast is accordingly prepared.
To reduce the risk of inductive interference the sensor must be properly grounded (screening on both
sides).
Heating
The sensor disposes of an electronically controlled 18 W heating within the sensor head.
The heating is supplied together with the sensor electronics. Under most climatological
conditions the heating prevents blocking of the moving sensor parts (see illustration).
The cup rotor or the wind vane are not heated. In case of icing or formation of ice at the
moving sensor element the function is restricted for the period of icing.
Maintenance
The sensor design permits long periods of maintenance-free operation. We therefore recommend a regular visual
verification of the north setup of the wind direction sensor as well as a sensor calibration of both sensor types every
two years. With problems, which cannot solve you, do not hesitate to contact our LAMBRECHT meteo service under:
