Casella Wind Direction Sensor

178037C Wind Direction Sensor by Casella

SYSTEM 1 - Transmits data directly into a PC over distances up to 50 m.

The wind speed and direction sensors are mounted on a cross arm. No sensor interface module is required, merely a junction box. The outputs from the sensors are linked via an Inline Connection Box to the RS 232 port on the PC.

A Universal 12 V Power Supply is also included to provide power for the sensors.

SYSTEM 2 - Transmits data to a PC over distances between 50 and 500 m*.

The wind speed and direction sensors are mounted on a cross arm which includes a signalconditioning interface that generates an RS 485 output. This output passes via an RS 485 to RS 232 Signal Converter to the PC.

A Universal 12 V Power Supply is also included to provide power for the sensors.

*For distances greater than 500 m, please contact the Casella CEL Sales Department.

SYSTEM 3 - Transmits data directly into a Multimet display over distances up to 200 m. Multimet systems can be networked.

The wind speed and direction sensors are mounted on a cross arm. No interface module is required, merely a junction box.

Power for the sensors is provided by the Multimet.

The wind sensing heads for all three systems utilise OEM sensors manufactured by Casella CEL.

The anemometer uses a non-contacting optical encoder transducer providing a pulsed 0 – 5 V output (frequency directly proportional to wind speed).

The windvane employs the very latest Giant Magneto Resistive (GMR) magnetic sensing technology to offer accurate, frictionless sensing with zero dead-band at north.

Both sensors are manufactured from high quality anodised aluminium, which guarantees functional reliability even under the harshest of environmental conditions. The sensors are mounted on a zinc galvanised, steel cross arm using corrosion resistant fittings. U-bolts can be provided for fitting to masts from 50 – 115 mm in diameter. Heated versions of both sensors are available if required.

For Systems 1 and 3, NMEA signals are sent directly to the PC, while for System 2, RS 485 is used as this allows noise free signals to be transmitted over longer distances.
