Abstract: A system (200) monitors a load associated with a load carrying member. The system (200) may include a voltage divider (240) and a computer device (250). The voltage divider (240) measures inductance associated with load sensing elements (210) that monitor the load carrying member. The computer device (250) determines displacements of the load sensing elements (210) based on the inductance associated with the load sensing elements (210) and determines the load associated with the load carrying member based on the displacements of the load sensing elements (210). The system may be designed to be portable and/or DC powered.
