What's In The Box?

Product Overview

The WindSonic Option 1 sensor used in this system has an RS232 output and has a cable distance of 15m. If cabling distances are longer than this we can quote as required. For cable lengths over 20m a WindSonic Option 2 sensor with RS422/485 output is required - please contact us for a quotation.

The sensor is linked with the RS232 cable to our IP65 rated WS-15A Display Unit providing a clear digital readout of wind speed and direction plus a wind direction arrow with cardinal points. The display enables set-up of an optional wind speed alarm and provides an RS232 data output to connect to a SpaceLogger W10 or SpaceLogger W8 Wireless data logger or PC.

The system comes complete with a 0.9m anodised aluminium mounting mast and mains plug power supply. 12V UK or World plug options are available.

Lightning Protection

All FlexiMet systems are supplied without lightning protection as standard. Should you require additional protection for your installation, please contact us for a quotation.
