Pavement Mounted Snow Sensor for Snowmelt Systems
Warmzone's pavement-mounted snow sensor is typically used for large commercial snowmelt projects or other projects where the most accurate moisture detection is critical. When conditions warrant, the pavement-mount snow signals the system's master controller activating the ClearZone radiant heat system so that it operates only while needed. The efficiency of this system minimizes energy costs but does not sacrifice the snow melting effectiveness. Snow sensors / switches mounted directly in the surface of the area to be heated provide reliable, fully automated snow melting for radiant heat snow melting systems.
The automated snow melting system relies on the snow sensor to signal the controller to send power to the heat cables and heat the driveway or pavement. The sensor has an adjustable set point, and most systems are set to activate the controller when temperatures are below 39°F (3.3°C) and moisture of any type, including water, snow, sleet or ice is present. After the moisture element has dried, the unit's built-in, 5-hour, hold-on timer keeps the system operating to ensure that the surface area is completely dry so no ice forms - further ensuring the efficiency of the snow melting system.
Because the snow melting system sensor accurately measures pavement temperature by compensating for its internal heating, it eliminates the cost and complexity of a separate pavement temperature sensor. For optimum system performance and efficiency, the sensor is typically mounted close to the deicing system's heat cable to ensure that the pavement and sensor become dry at about the same time.
The sensor features a new mounting system that provides accurate alignment with the pavement surface. Six available conduit locations add to flexibility and simplicity of the installation. 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.
The pavement-mount snow sensor is a rugged, yet sophisticated piece of equipment. The unit is designed so that only brass, epoxy, and stainless steel are exposed to the surface of the pavement. Precision machining gives these products a handsome appearance that are sure to please the building owner, engineer, and architect.
Aerial mounted snow sensors are commonly used for residential radiant snow melting systems.
