Aviation Laser Ceilometer - DEGREANE HORIZON - TL320 The DEGREANE HORIZON TL320 Laser ceilometer is a cloud height sensor used mainly at airports to provide cloud base altitude, vertical visibility and sky condition parameters. Operating according to the LIDAR principle (Light Detection and Ranging), the TL320 sensor can report up to three cloud layers. The TL320 provides the latest state of the art technical development in the field of Laser source and Signal Processing. The transmitter unit uses a pulsed MOPA laser which offers a very high reliability. The wavelength (1550nm) is particularly suited for measurement under all weather conditions and guarantees a fully eye safe class 1 (complies with ANSI - Z - 136, IEC 825, EN 60825-1 norms). The TL320 sensor can be used as a standalone instrument or integrated into a meteorological system. TL320 ceilometer includes a pedestral base, allowing beam tilting from 0° to 90°. The tilting position insures a total protection against direct solar radiation, and facilitates field testing against a hard target. The ceilometer’s opto electronics are enclosed in a rugged housing protecting the sensor from extreme operating conditions. An automatic blower with heater ensures to keep the window clean and dry under all weather conditions.
