Advanced technologyself de-icing/water shedding capability
Overview
0872E3 is a sensor that measures precipitation transitions between liquid and solid states. The sensor is designed to measure the intensity and duration of ice storms and differentiates rain from freezing rain as temperatures approach freezing. Ice accumulations as low as 0.005 inches (0.13 mm) are detected. Read MoreImages
Detailed Description
0872E3 detects ice accumulation on an ultrasonic axially vibrating tube and communicates the associated frequency changes through an RS-232 or digital current loop data link.
The 0872E3 is mounted on a pole and is designed to operate continuously in an outdoor environment. The 0872E3 requires only period recalibration; no other maintenance is normally required.
The 0872E3 consists of four functional assemblies: a Main circuit card assembly (CCA), an Output Interface CCA, a Filter assembly, and a Strut and Probe assembly. The CCAs and all electrical connections are contained within the 0872E3s housing.
