4 2 GENERAL DESCRIPTION -SYSTEM industrial ice detecting sensor system is a modern, optical go/no-go ice sensor for general purpose industrial applications, including 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 very little energy. Powered by a 5W solar panel system, it is suitable for use in remote locations 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 sticks to the optical surfaces for sensing. 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 rain and 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, an optical probe, a plastic housing, and a lightweight blue cable that connects to its host system. Standard cable length is 6 feet (1.3 meters) but can be greatly extended on special order. Model 9734 indicates the presence of ice. An optional protective cage is available to help guard against falling chunks of ice and other debris. Figure 2 a, b -- Ice*Meister Model 9734-SYSTEM senses rime ice, frost etc (left) and clear ice (right). 2 4/15

5 3 SPECIFICATIONS SENSITIVITY TO ICE ACCUMULATION: Better than 0.01 inch (0.254 mm) of rime or clear ice. ORIENTATION: Unit installs horizontally, with the top of its housing facing UP, and probe facing into the wind. OPERATING / STORAGE TEMPERATURE: - 40 deg C to + 50 deg C. Not warranted to detect ice above 0 deg C. ELECTRICAL INPUT: Any clean DC voltage from 8 VDC to 30 VDC Current draw at standard 24 VDC is < 100 ma max red wire = + volts DC black wire = earth ground ELECTRICAL OUTPUT: 1 set of single pole, single throw, normally open relay contacts, rated at 1 Amp, 50 volts non-inductive (see attached relay data sheet) Closed when frost is present, Opened when frost is absent. Green and white wires = relay contacts VISUAL OUTPUT: Probe turns BLUE to indicate ice is present and relay contacts are closed. CONNECTING CABLE: 0.1 inch (2.54 mm) diameter lightweight Teflon four-conductor shielded cable, wire ends stripped and tinned Red, black wires: Power in Green, white wires: Relay contacts out Length: 6 feet (1.3 meters) standard DIMENSIONS: Sensor head: Height: 2.5 inches (63.5 mm) Width: 1.25 inches (31.8 mm) Depth: 1.0 inch (25.4 mm) Probe extension from housing: 1.0 inch (25.4 mm) Mounting plate: Length: 11 inches (280 mm) Width: 4.0 inches (102 mm) Thickness: 0.5 inch (12.7 mm) WEIGHT: 4 ounces (113 g) exclusive of mounting hardware 3 5/15

With 9734 connected to a 9-volt battery or suitable DC power supply, submerge the probe into a tumbler of clean tap water. The tumbler must have a wide mouth, and be made of clear glass or plastic, as shown below. Observe the blue LED illuminates, the relay *clicks* closed, and continuity tester confirms the relay contacts are closed, as Testing I, above.
