  • Visibility Sensors

    Biral is the manufacturer of the VPF and SWS Visibility and Present Weather sensors which are used worldwide.

  • Biral - Model SWS-050 - Visibility Sensor

    Biral - Model SWS-050 - Visibility Sensor

    The SWS-050 Visibility Sensor is optimised for use in applications where accurate and reliable visibility measurements are required. The forward scatter measurement principle and unique design ensure the output is both accurate and reliable in all weather conditions.

  • Biral - Model SWS-050T - Visibility Sensor

    Biral - Model SWS-050T - Visibility Sensor

    The SWS-050T is designed for use in road and tunnel applications where accurate and reliable visibility measurements are required. The forward scatter measurement principle and unique design ensure the output is both accurate and reliable in all weather conditions and will not be influenced by local light sources, even those that flash.

  • Biral - Model SWS-100 - Visibility Sensor

    Biral - Model SWS-100 - Visibility Sensor

    The SWS-100 is optimised for use in applications where accurate and reliable visibility measurements are required alongside basic present weather measurements. The forward scatter measurement principle and unique design ensure the output is both accurate and reliable in all weather conditions and will not be influenced by local lights sources, even those that flash.

  • Biral - Model SWS-100LW - Visibility Sensor

    Biral - Model SWS-100LW - Visibility Sensor

    The SWS-100LW is optimised for use in applications where accurate and reliable visibility measurements are required from a low power, light weight sensor. When only solar power is available or when reliance on batteries is essential the SWS-100LW is the perfect choice for a fully featured visibility sensor. With a power consumption of just 2.9W the sensor places a minimum burden on the supply system and can be intermittently powered for even lower...

  • Biral - Model VPF-510 - Visibility Sensor

    Biral - Model VPF-510 - Visibility Sensor

    The VPF-510 Visibility sensor offers reliable visibility measurement in a robust and highly corrosion resistant package. The serial digital output supplemented by analogue outputs and switching relays makes this sensor particularly suited to offshore and marine applications.

  • Biral - Model VPF-710 - Visibility Sensor 710

    Biral - Model VPF-710 - Visibility Sensor 710

    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...

  • Present Weather Sensors

    Biral forward scatter Present Weather Sensors measure visibility and report precipitation type and intensity. These compact sensors can identify a wide range of precipitation types including drizzle, rain, snow, hail, freezing rain and other forms of frozen precipitation. Precipitation type is reported using a combination of WMO Table 4680 and METAR codes. The range of precipitation types identified varies with sensor model.

  • Biral - Model VPF-750  - Visibility & Present Weather Sensor

    Biral - Model VPF-750 - Visibility & Present Weather Sensor

    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.

  • Ambient Light Sensors

    Ambient light sensors measure background or ambient light levels. Biral sensors are typically used in aviation Runway Visual Range (RVR) systems and have a well defined field of view.

  • Biral - Model ALS-2 - Ambient Light Sensor

    Biral - Model ALS-2 - Ambient Light Sensor

    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.

  • Thunderstorm / Lightning Detectors

    Biral Thunderstorm Detectors are self-contained standalone devices that detect the presence of all forms of lightning including intra-cloud, cloud to cloud and cloud to ground. Additionally our sensors can warn of the risk of overhead lightning before the first discharge. The unique quasi-electrostatic operating principle developed by Biral ensures very high detection efficiency whilst maintaining a false alarm rate that is almost zero.

  • Biral - Model BTD-300 - Thunderstorm Detector

    Biral - Model BTD-300 - Thunderstorm Detector

    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.

  • Biral - Model BTD-350 - Thunderstorm Detector

    Biral - Model BTD-350 - Thunderstorm Detector

    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...

  • Biral - Model AOT-100 - Aerosol Optical Tweezer

    Biral - Model AOT-100 - Aerosol Optical Tweezer

    The AOT-100 allows users to hold airborne particles for extended periods with ease. Holding particles in an optical trap enables many different parameters to be studied continuously over times varying from milliseconds to hours.
