Our bestseller Cloud Ceilometer CBME80

Cloud Ceilometer CBME80 

Cloud Ceilometers
The cloud ceilometer CBME 80 is a stand-alone instrument designed for fixed and mobile installations where accurate and reliable cloud height information is required.

The design is based on the LIDAR principle. The light emitting component is a low power diode laser with the output power limited to eye-safe level. Real time digitizing technique is employed in signal detection and the powerful 80C186 microprocessor is used in signal processing.

Data presentation 

CBME 80 has outputs for different types of display and recording units. An RS-232C interface supports local control, test and data acquisition. For remote control and data acquisition there is a built-in FSK modem.

Maintenance 

A built-in test system indicates failures in the event of a malfunction. The electronics are located in three easily replaceable subunits, i.e. a power unit with an EMI unit included, a master printed circuit board and a power sensor board.

The subunits, as well as the laser diode and the avalanche diode, which are placed on the master circuit board, can be replaced without realignment.

Features 

  • Reliable operation - MTBF 100 000 h
  • Easy installation and maintenance
  • Very long laser life (calc. 10 years)
  • 25 000 ft measuring range capability
  • Low weight and low power consumption
