The PPS Aerostrip provides a simple and convenient replacement for traditional pressure tapping or pressure-sensitive paint. It is a low profile, rapidly deployable air pressure sensing strip for aerodynamic measurement and surface optimization for motorsport and aerospace applications. The AeroStrip consists of an extremely thin strip of sensors that can be applied, and reapplied, non-destructively to test surfaces for pressure measurement due to reusable masked adhesive backing. It has comparable accuracy to pressure tapping in subsonic flow, but with a tiny fraction of the setup time and cost. With Aerostrip, you can quickly take non-destructive outside pressure measurements from control surfaces, live or in a wind tunnel, enabling faster turnaround and optimization of aerodynamic components.

The VPF-750 Visibility and Present Weather sensor is the most advanced in Biral’s product range. Its enhanced performance allows the reporting of freezing precipitation in addition to the weather codes typically available from a forward scatter sensor. The sensor is designed for use in aviation applications where extended weather information, including past weather, is required for inclusion in METAR reports. The sensor is also well suited to research applications and use in meteorological observation networks. The unique backscatter receiver combined with accurate external temperature, humidity and precipitation sensors gives the VPF-750 unparalleled abilities in distinguishing frozen from liquid precipitation, with the added advantage of identifying freezing precipitation. The sensor reports both WMO table 4680 and METAR codes to simplify integration in to host systems. A wealth of other data is provided including a transmissometer equivalent EXCO.

The BTD-200 Lightning Warning System is a complete detection and warning system which has been developed from the Biral range of professional, aviation grade lightning detection systems. It reliably detects the local presence of all forms of lightning out to a range of 35km (22 miles) from the sensor. Designed to be installed and set up by non-specialist contractors, it comes complete with a power supply for the detector and the essential PC application – Lightning Works – for monitoring and warning of approaching thunderstorms.

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) application

The BTD-350 Thunderstorm Detector is a standalone sensor that reliably detects the presence of all forms of lightning to a range of 83km. 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-350 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-350 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.

The ALS-2 Ambient Light Sensor is designed to measure background luminance as part of a Runway Visual Range (RVR) system. Mounted alongside the runway the ambient light sensor is often deployed with a visibility meter to provide the data necessary for calculation of RVR. Designed to comply with specifications and guidelines produced by the International Civil Aviation Organisation (ICAO), World Meteorological Organisation (WMO) and the Federal Aviation Administration in the USA (FAA), the ALS-2 meets all the requirements for use in typical RVR systems. The ability to connect the sensor directly to a Biral visibility or present weather sensor and have the background luminance data incorporated into the visibility sensors data string simplifies system design and construction.

The SWS-250 is optimised for use in aviation applications where both visibility and extended present and past weather information is required. The sensor measures: visibility (MOR, EXCO and TEXCO), fog, haze, drizzle, snow, hail and other non-frozen precipitation according to WMO table 4680. METAR coded outputs are also provided. For ultimate visibility performance the visual range extends to 99.99km allowing use in meteorological observation networks and research applications. The enhanced present weather information from the SWS-250 is due to the backscatter receiver which allows detailed precipitation analysis and the use of algorithms developed for Biral’s flagship VPF-750 present weather sensor.

CMOS sensors are used within commercial grade Digital SLR cameras as a replacement for the more expensive CCD. These CMOS sensors are extremely sensitive to IR light, which can lead to discolouration. IR cut filters are used to block the IR light, meaning that photographs are taken with life-like colours. Colour Glass Filters can be used in variations of Bandpass, Long pass and Short pass, depending on which wavelengths of light need to be blocked resulting in different key areas being more easily distinguished. Knight Optical offers Colour Glass and IR cut filters for such an application, with a wide range of band widths and cut on/off wavelengths. As above these are available as Bandpass, Long pass or Short pass filters and we can also offer customised filters with coatings specific to the wavelength of your choice. We hold a massive inventory of IR cut, Bandpass, Long Pass and Short Pass filters: Read PDF for more info….
