Overview

0872F1 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 0.13mm (0.005 inches) are detected.

Technical Description

0872F1 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 0872F1 is mounted on a pole and is designed to operate continuously in an outdoor environment. The 0872F1 requires only period recalibration; no other maintenance is normally required. The 0872F1 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 0872F1s housing.
