Professional Weather Stations - Barber Insys

High precision compact weather stations for measuring & reporting present weather(Now Cast) data to road service network managers & road weather bureau's.

The WSXXX-UMB family of meteorological compact weather stations offer an "All-In-One" solution, which simplifies installation & reduces costs compared with using multiple individual weather sensors. One cable.

The  Lufft R2S-UMB represents a high performance radar based precipitation sensor for determining type & amount & fitted with a heater for cold climate applications.

Special models developed for withstanding harsh environmental exposure such as the risk of icing, marine, & high vibration levels experienced on wind turbines.

VENTUS-UMB Metal Heated Robust Ultrasonic Wind Speed Sensor for the most demanding Environments.

Measure wind speeds up to 90m/s, with a sample rate up to 240 single measurements per second.

Metal Housing & 200W heater gives ice fee operation in the most demanding environments.

Reliable sensor operation means lower cost of ownership.

Digital & analogue outputs. Field proven in Marine & Cold climate environments.

The perfect replacement for any wind turbine yaw control system.



Designed for cold climates & harsh conditions.

VENTUS is corrosion tested for seawater & proven for ice free operation. It gives the best accuracy with maintenance free operation.

Recommended for:
wind turbine control
- building automation


Lufft Ventus. A robust heated aluminum housed ultrasonic wind speed/direction sensor

Sensors are addressable & operate on an RS485 network. Several digital output protocols are configurable such as MODBUS, SDI-12, UMB Binary, UMB-ASCII. An 8 channel digital converter module is available for control systems requiring analogue input signals from sensors that do not have analogue outputs as standard.


The WndBridge (Nor-Cal Controls Inc.)enables wind farm operators/owners to reduce maintenance cost  by replacing old cup & vane anemometers that are prone to mechanical failure (or get iced up & shut down the turbine for safety reasons ) & replace them with a Lufft VENTUS, without having to replace their existing PLC.
