WARMZONE SNOW MELTING

Pavement-Mounted Snow Sensor for Radiant Heat Snowmelt Systems

DESCRIPTION The pavement-mounted snow sensor is ideal for commercial snowmelt projects or any other project where the most accurate moisture detection is critical. This sensor allows the ClearZone radiant heat system to operate only while needed, which minimizes energy costs without sacrificing snow melting effectiveness. The sensor signals for radiant snow and ice melting at pavement temperatures below 38°F (3.3° C) while moisture in any form—including water, snow, sleet or ice—is present. Once the moisture element has dried, the built-in, 5-hour, hold-on timer keeps heaters operating to help ensure complete snow and ice melting.

This device accurately measures pavement temperature by compensating for its internal heating. This eliminates the cost and complexity of a separate pavement temperature sensor. For improved efficiency, products mount close to the deicing heaters to ensure that pavement and sensor become dry at about the same time. The new mounting system provides accurate alignment with the pavement surface. Six available conduit locations add to installation flexibility and simplicity. The sensor subassembly is field replaceable without disturbing the pavement. The sensor is an NEC Class 2 device operating from customer supplied 24 volts AC. It provides a floating Form A, low-voltage, 2 amp relay contact for interfacing external heater control contactors. Only brass, epoxy, and stainless steel are exposed to the pavement surface. Precision machining gives these products a handsome appearance that will please the building owner, engineer, and architect.
