    • The electronic weight monitor of this invention comprises a control assembly including a switch operable to selectively control electric power to the weight monitor, a relay connected to an input contact to a switch, a lamp connected to a ground and to one of the output contacts of the relay, and a warning means connected to a ground and to the remaining output contact of the relay. A load cell housed in a container comprising a base having sidewalls and a lowermost terminal wall is provided. A platform having an uppermost terminal wall and sidewalls operable to slidably engage the sidewalls of the base, and an urging means operable to urge the base toward the platform are provided. The load cell includes a permanent magnetic field disposed in the base, and a reed-type switch which has one of its reeds connected to a ground and its opposing reed connected to the remaining input contact of the relay. The electronic weight monitor may include a magnetic field having adjusting means operable to selectively position the magnetic field relative to the base.
