All-Weather - Model 6495 - Freezing Rain Sensor - Brochure

The FAA certified, Model 6495 Freezing Rain Sensor uses an ultrasonic axially vibrating probe to detect the presence of icing conditions.  The vibrating frequency of the probe decreases with the accumulation of ice, frost, or wet snow.  After ice has accumulated on the probe to a predetermined thickness, the AWOS DCP instructs the sensor to turn on it`s internal heaters to deice the probe.
