Transmissometer
The 8400-eMOR Transmissometer measures the atmospheric extinction coefficient, providing a highly accurate visibility measurement suitable for aviation applications, including the reporting of Runway Visual Range (RVR).
The sensor heads are mounted on integrated ICAO-certified frangible aluminum lattice masts, which are bolted to a foundation base plate. The optical units are mounted at the top of the inner mast, while the main electronics control box is mounted on the side of the outer mast for easy access.
A window-conditioning fan unit attached to the outer mast provides a heated air curtain for the optical unit windows, actively maintaining them in a clean and dry condition during fog, rain, or snow. Transmissometers are typically mounted in groups of one, two, three, or four along each runway to support CAT III-B operations.
