When it is Too Cold for Normal Wind Sensors

The Wilh. LAMBRECHT (Germany) presents their new cold-climate wind sensor. The PROFESSIONAL-IX 2.0 is a robust, compact and very reliable wind sensor for the registration of wind direction and speed. The PROFESSIONAL-IX 2.0 is designed for solid operation under extreme climate conditions and is therefore especially suited for the use in wind turbines under cold climate conditions. The integrated 125 W heating of the moving parts allows the sensors to operate in a wide temperature range down to –40 °C. The heating is effectively decoupled from the electronics. But when the heating is switched on, the temperature inside the housing will stay high enough for the electronics to work even at –50 °C.

Due to the tested Ingress Protection Rating of IP65 and the usage of sea water resistant aluminium for the spray and dust tight housing the sensors are also suitable for offshore applications.

The sensor is available with different output signals like 4…20 mA or 0…10 V without additional signal converters. The electronics for the contact less signal detection, processing, output and heating control are integrated inside the PROFESSIONAL-IX 2.0. The linearised output signals can be customized for special applications.
