  • DIN rail or enclosure for easy mounting
SKU: 5721-01 Categories: ,

Description

The Model 5721 Passive Road Surface Sensor provides actionable information about the roadway to road weather professionals. The sensor is installed in the roadway and measures the surface temperature and the surface condition as dry, wet, ice watch and chemically wet. The sensor is well suited for roadways, ice-prone bridges, elevated roadways, entryways, parking garage ramps and loading docks.

The road surface sensor connects to signal conditioning modules for connection to HSE’s line of dataloggers. The signal conditioning modules are DIN rail mountable and can be provided in a mountable enclosure as an option.

The surface sensor measuring elements are molded in a resilient epoxy compound with thermal properties that closely match the roadway surface. It works on thermally passive principles; no artificial heating or cooling is used that may alter the measured environment. The maintenance-free design features corrosive-resistant electrodes to derive the presence of moisture on the roadway surface. The sensors are intentionally designed as low cost units, so replacement is economical when replacement is required due to road surface milling, re-paving, etc.
