Pavement-Mounted Snow Sensor
The pavement-mounted snow sensor is ideal for commercial projects or any other project where the most
accurate moisture detection is critical. This sensor allows the snow melting system to operate only while needed, which minimizes energy costs without sacrificing snow melting effectiveness.
The sensor signals for 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.
