HSS VPF-730 Visibility and Present Weather Sensor
The Visibility and Present Weather Sensor is the best combined visibility and present weather sensor on the market today.
Features
Measures visibility AND fog density.
Very low power requirements.
Highly resistant to sea-water corrosion.
Data Output
The Visibility and Present Weather Sensor is configured with RS-232C signal output as standard with RS-422 communications available as an option.
Construction
Corrosion is not an issue with HSS sensors as they are constructed from hard anodised, high grade aluminium which provides a long lasting superior finish.
Maintenance and calibration
The Visibility and Present Weather Sensor is fully calibrated at the time of manufacture. Routine maintenance, including a check on calibrations, can be performed easily by one person in a matter of a few minutes and a re-calibration takes only slightly longer.
Operation in temperature extremes
The Visibility and Present Weather Sensor operates in temperatures ranging from -50º C to +60º C. For operation below -32º C the heated version is recommended.
The Visibility and Present Weather Sensor System
The Visibility and Present Weather Sensor is also supplied with a stainless steel mounting kit.
