SWS-250 Visibility and Present Weather Sensor
The Visibility Sensor measuresvisibility and present weather conditions and well as providing information on past weather.
Features
Visibility measurement range 10m to 75km.
MOR and EXCO output.
Serial data output (RS232 & RS422/RS485).
Very low power requirements.
Data Output
The Visibility Sensor is provided with RS-232C and RS422/RS485 serial data outputs as standard for reliable and simple connection to a wide range of monitoring and control systems.
Construction
The Visibility Sensor is a single lightweight unit and can easily be installed by one person.
Maintenance and calibration
The Visibility Sensor is fully calibrated at the time of manufacture.
