Cloud Ceilometer - CBME80B

The Biral cloud ceilometer CBME80B is used for measuring cloud base height and vertical visibility up to 7500m. The celiometer provides up to three layers of clouds and is suitable for sky profiling for both fixed and mobile application in aviation and meteorology on land, ships and offshore.

Ceilometer design is based on the LIDAR principle; diode laser emits light, that is detected by a light detector. Real time signal processing is boosted by a powerful microprocessor in combination with a FPGA.

Ceilometer is easy to install and maintenance. Laser has very long life (10 years). It is characterized by low weight and low power consumption.

The cloud ceilometer has outputs for different types of display and recording units. An RS-232 and RS-485 interface supports local control, test and data acquisition. There is a built-in FSK modem for remote control and data acquisition.
