Abstract
A real-time snow load measuring system, for determining when an unsafe condition exists upon a roof top surface of a dwelling, having a sensor unit and a control unit. The sensor unit is mounted on the roof top surface, and includes a frame having a base plate and a sensor plate. A fluid substance is located between the base plate and sensor plate, such that the fluid substance is compressed, creating a fluid pressure, upon the presence of a snow load upon the sensor plate. A transducer is in communication with the fluid substance, and is capable of measuring the fluid pressure and producing a transducer output which is proportional to actual snow loading upon the sensor plate. The control unit receives the transducer output, provides a calibrated output on its display unit reflecting average snow loading on the roof top surface, and can also produce a warning when a predetermined maximum permissible roof loading level has been exceeded.
