What Is a Ceilometer?

The laser ceilometer emits laser pulses from the ground. By receiving the backscattering of this light pulse by the atmosphere, it can detect and analyze the composition of the atmosphere at different heights. The moisture vapor component contributes greatly to the backscattering of light. Analyze Izumo height information. Because of its working method and precise design and manufacture of the product, it has excellent performance and reliability under almost all weather conditions. Laser cloud altimeter, its detection altitude is generally 15 kilometers. The laser ceilometer uses an advanced single lens design, which also shows excellent performance for low-altitude atmosphere. It can not only detect and analyze the three-layer cloud data, but also show good performance for vertical visibility and cloud detection during precipitation. The laser receiving unit uses the current advanced detection technology to achieve a high detection accuracy, which enables it to quickly measure and detect the thin cloud layer under the solid-state cloud with a certain penetration performance.

Ceilometer

Highly reliable operation.
Easy to install and maintain.
Long laser life
26 000 feet [8000 meters] of measurement range.
Light weight and low power consumption.
Fixed or portable design.
Easy interface, RS232 serial port 422 or Ethernet
With a two-way single lens design, it has very low interference and can enhance near-field performance. Very clear laser pulse shape and real-time digitization technology, utilizing the latest high speed, high dynamic range scan converters. It, combined with interlaced scanning technology, provides excellent
Capable of operating in a variety of environmental conditions, including from the equatorial hot and humid zone to the desert. Heating window with internal heating and cooling and double-layer design make the internal system maintain a stable temperature under various weather conditions and eliminate internal condensation. The standard is to use solar optical filters to protect the internal optical components from direct solar radiation. All electrical connections to the components are protected against surges. In the event of rain, snow or no cloud base being detected, vertical visibility is reported.
The data port provides standard data formats via Ethernet, RS232 and RS422 standards. The cloud detection algorithm is built into the instrument's firmware, and a graphical cloud analysis software workstation can be optionally provided in the 8200-CHS. If necessary, a signal return can be obtained with each scan. Internal RS-232C interface and Ethernet interface, support local and remote control, test and data acquisition. You can also use a radio station,
