GENERAL DESCRIPTION
Ice Sensor Model 9734-SYSTEM industrial ice detecting sensor system is an optical go/no-go ice sensor for general purpose industrial applications, such as wind power turbines, HVAC cooling towers, radio and TV broadcast towers, oil and gas rigs, vehicular bridges, overpasses, etc. It is completely self-contained. No external components are required.
Model 9734 consumes little energy; powered by a 5W solar panel, is suitable for use in remote locations.
9734 monitors the optical characteristics of whatever substance is on the probe. If AIR is on the probe, output indicates NO ICE. If H2O is on the probe, output indicates ICE ALERT. Liquid water simply runs off by gravity, but ICE adheres to the optical surfaces. There are no moving parts.
Unit detects H2O in its solid and liquid phases, including rime ice, snow, frost, clear ice, standing water. Gravity removes ice melt from the optics.
This sensor has no specified accuracy, and is not intended to be used as an analog measuring instrument of any kind.
Model 9734 contains a small embedded circuit board, a plastic housing, and a lightweight blue cable that connects to its host system. Standard cable length is 6 feet, but the cable length can be greatly extended by if necessary.
Model 9734 indicates the presence of ice. An optional protective cage is available to help guard against falling debris. Various mounting options are available for diverse applications.
