Based on remote transceiver Sentinel nodes, Signal Fire Remote Sensing System provides remote management of assets in challenging outdoor environments. Nodes interface with sensors, extract data, and send long-range transmission of data in unlicensed ISB bands that sustains signal strength through terrain, structures, or weather. Intrinsically safe and rated to Class 1 Div 1 standards, nodes interface with thermocouples, turbine flow meters, load cells, and potentiometers.
