Accurately Detects Presence of Icing Conditions Down to 0°
C
All Weather, Inc. has
announced that the Model 6495 Freezing Rain Sensor has received
approval from the FAA for use in airports across the US. The
Freezing Rain Sensor accurately detects the presence of icing
conditions at temperatures as low as 0�C. The unit senses an
occurrence of freezing rain by the change in the probe tip's
oscillating frequency; changes are detected even with the
accumulation of ice, frost, or wet snow. Once icing conditions are
detected, they are analyzed using the AWOS freezing rain algorithm
and transmitted for remote display to airports and crews.
The Model 6495 Freezing Rain Sensor's robust design allows the
unit to completely melt up to 3.8 mm of ice within 30 seconds at
-20° C. After deicing, the sensing probe cools quickly and is
ready to sense ice formation again. Water droplets are prevented
from collecting around the probe in still air conditions. In
addition, the sensor's ability to shed water eliminates false
signals due to refreezing at the base of the unit when the
atmosphere does not contain liquid water to form ice on the probe.
Extensive internal self-tests and fault diagnostics guarantee
accurate measurements.
Automated Weather Observing System (AWOS)
The Freezing Rain Sensor is part of AWI's Series 900 AWOS. In
addition to freezing rain, the AWOS measures and reports wind
speed, wind gusts, wind direction, relative humidity, temperature,
visibility, precipitation, altimeter setting, density altitude,
cloud height and sky condition, present weather, and lightning-all
essential data for the safe and economic operation of any airfield,
large or small.
AWI's AWOS system is designed to meet the stringent standards of
the FAA, as well as those of the international governing bodies
International Civil Aviation Organization (ICAO), World
Meteorological Organization (WMO), and Transport Canada. All
systems measure and report essential weather information and
include full Remote Maintenance Monitoring capabilities to ensure
continuous monitoring. The All Weather, Inc. Model 6495 Freezing
Rain Sensor is available from stock. Prices start at $16,500.
