Sensor Description

The MTECH Systems ceilometer sensors are stand-alone instruments designed for fixed and mobile installations where accurate and reliable cloud height, cloud ceiling, vertical visibility, cloud amount or sky condition detection are required.

The ceilometer device detects up to 4 layers / bases. The detector design is based on the LIDAR principle and is designed around an InGaAs laser diode. The light emitting component of the device is a high specification diode laser with the output power limited to an eye-safe level. Real time digitizing techniques are employed in signal detection and a powerful 32 BIT microprocessor and FPGA are used in signal processing in the ceilometer.


The popular site is a valuable resource on the use of ceilometers to display the state of the sky,  including cloud detection,  cloudbase height measurement,  detection of planetary boundary layer,  virga,  fog,  rain  and other hydrometeors in the atmosphere

Environmental Performance

The 8200-CHS performs in all environmental conditions from desert to the wet equatorial tropics. The heated windows and the double skinned design with internal heating and cooling maintain the internal systems at stable temperature and eliminate internal condensation under all conditions. The internal optical components are protected from direct solar radiation by an optical solar filter. There are no internal moving parts as seen in inferior ceilometer designs. All electrical connections to the unit are surge protected. During rain and snow or in the absence of a detectable cloud base the vertical visibility is reported.

Data Presentation Method

The 8200-CHS ceilometer has outputs for many different types of display and recording units. Backscatter data is transmitted from the ceilometer to enable graphical display to the end user. An RS-232C, RS-485 or ethernet interface supports local control, test and data acquisition from the ceilometer. For remote control and data acquisition an FSK modem. Wireless radio, microwave, conventional or DSL modem can be used to deliver data from the ceilometer.

Output messages

The 8200-CHS ceilometer has 21 different formats of output messages available as standard ensuring easy setup for your application. The ceilometer device emulates with fully verified accuracy the CT12K , CT25K and CL-31 message formats and also outputs formats such as the MTECH RAW backscatter message. A further 19 optional messages for compatibility with systems or software designed around the CHM, CBME, CIRRUS, 83XX and ALC ceilometer devices are available. The innovative MTECH boudary layer / mixing height estimate message format 22 is also available as an option.

Maintenance Information

A built-in test system indicates failures in the event of a malfunction of all critical parts of the ceilometer. The electronics are located in 4 easily replaceable subunits, i.e. a Power supply, Processor card, a  Laser Module and Sensor Module. The subunits can be filed replaced with spare parts without adjustment or re-calibration of the ceilometer.
