The 80171 Cloud Ceilometer is a stand-alone instrument designed for fixed and mobile installations. It detects clouds using the LIDAR principle with a low power diode laser that is eye safe.
This ceilometer has a detection range up to 25,000 feet and is very accurate. The 80171 is highly reliable, with demonstrated mean-time-between-failures of over 150,000 hours.
The main advantages of the 80171 are its size, weight, power requirement, and modern design. The small size and weight make the 80171 ideal for mobile use and facilitates easy maintenance by one person. The ceilometer can be carried in one hand and can operate from a 12 VDC battery or solar supply, or from AC mains power. The primary advantage of the 80171 is its modem electronic design, which reduces the number of replaceable subassemblies to two items and allows complete field replacement without adjustments or calibration.
The 80171 employs unique digital signal processing techniques that enables detection of up to five cloud layers from an eye-safe laser. This special design also extends the life of the laser beyond 10 years. The 80171 has outputs for different types of display and recording units. An RS-232 interface supports local control, test, and data acquisition. For remote control and data acquisition, there is an internal FSK modem. A digital readout on the ceilometer enclosure provides cloud base and operating status information. The ceilometer has built-in test equipment for automatically adjusting its operating parameters and for self-diagnostics. The cyclic self-testing completely covers the ceilometer’s operation and reports current status in every output message, There are not periodic calibrations or adjustments required. The 80171 has been tested to IEC environmental standards for vibration, shock, impulse voltages, transients, operating temperature, and EMI susceptibility and emissions.
