Abstract: An electronic overload inspection and warning system for a roundsling having a strand positioned within a plurality of core strands and a cover. The system includes a wireless sensor system mountable to the roundsling. The wireless sensor system includes at least one strain gauge electrically connected with a wireless transmitter. The strain gauge measures strain on the strand. The system also includes a wireless base station and a carrier element. The wireless base station includes a wireless receiver configured to wirelessly communicate with multiple deployed wireless sensor systems. The carrier element is secured to the strand. The strain gauge is secured to the carrier element.
