Patent ID: 8841566

Claim:
A load cell assembly for measuring a load carried by a semi-trailer having a weight bearing support and a frame, the load cell assembly comprising: a load cell plate configured to be coupled to the semi-trailer between the weight bearing support and the frame, the load cell plate comprising— a body having a first thickness and a central longitudinal plane; a sensing section having a second thickness less than the first thickness, wherein the sensing section is generally parallel to and offset from the central longitudinal plane, the sensing section having a sensor mounting surface generally parallel to the central longitudinal plane; a strain focus opening spaced apart from the sensing section, wherein the strain focus opening extends through the body; and an attachment opening spaced apart from the sensing section, wherein the attachment opening extends through the body and is configured to receive a fastener to couple the load cell plate to the semi-trailer; and a sensor carried by the sensor mounting surface of the sensing section offset from the central longitudinal plane, and the sensor configured to detect a load related to a weight associated with the semi-trailer.
