The VPF-710 Visibility Sensor provides high quality visibility measurement in a compact and highly robust package.

The open design of the sensor head allows the free passage of air ensuring the visibility measurement is as accurate as possible in all conditions. Other features of the design ensure the correct response to all precipitation types as well as smoke and dust. The VPF-710 is highly resistant to disturbance from nearby light sources such as aviation obstacle warning lights, both constant and flashing. Even the latest generation of IR obstacle lights are not a problem.

The sensor is well suited to use in aviation applications due to the measurement accuracy, overall reliability and longevity. Full compliance with the visibility measurement requirements of the International Civil Aviation Organisation Runway Visual Range specification and easy integration of the Biral ALS-2 ambient light sensor makes VPF-710 particularly suited for use in Runway Visual Range (RVR) applications.

As standard the sensor is fitted with an extensive self-test monitoring capability which includes window contamination monitoring and output compensation. The VPF-710 can be AC mains or low voltage DC powered and hood heaters are available for use in areas prone to snow.

BTD-300 Thunderstorm Detector

BTD-300 Thunderstorm Detector
Hover over image to zoom
or click to view full size

The BTD-300 Thunderstorm Detector is a standalone sensor that reliably detects the presence of all forms of lightning to a range of 83 km. The unique quasi electrostatic operating principle gives the detector a very low false alarm rate and the ability to warn of the risk of overhead lightning.

The ability to reliably detect and range cloud-to-cloud lightning, which is typically much more common than cloud-to-ground strikes, makes the BTD-300 much more sensitive to the presence of storms compared to devices that rely on radio detection. The electrostatic operating principle allows the sensor to warn of the risk of overhead lightning before the first discharge occurs.

Virtually maintenance free in operation, the BTD-300 can either interface directly to an integrated system or be operated using the supplied PC compatible display and logging software. The optional warning relay module allows the sensor to automatically sound alarms whenever a storm approaches.

  • Warns of overhead lightning risk even before the first lightning discharge
  • Highly immune to radio interference which is the major cause of false alarms in traditional standalone detectors
  • 83 km (45 nm) detection range exceeds the US FAA requirements
  • Detects cloud-to-cloud as well as weaker but more common cloud-to-ground lightning
  • Detects charged precipitation
  • Meets FAA performance requirements for aerodrome use
  • Meets EN50536:2011+A1:2012 requirements for a Class 1 detector
  • Meets IEC 62793 performance requirements for a Class A detector
