Abstract: A load cell may include a bar having a supported end, an unsupported end and a sensor holding portion disposed between the supported end and the unsupported end. The load cell may further include a plurality of electronic sensors including a first strain gauge pair and a second strain gauge pair disposed along the sensor holding portion. The load cell may further include an interface member directly connecting the electronic sensors for weight calculation responsive to application of a load to the unsupported end. In some cases, the interface member may include a flex circuit.

Abstract translation: 测力传感器可以包括具有支撑端的杆，未支撑端和设置在被支撑端和未支撑端之间的传感器保持部。 测力传感器还可以包括多个电子传感器，包括沿传感器保持部分设置的第一应变仪对和第二应变仪对。 测力传感器还可以包括直接连接电子传感器的接口构件，用于响应负载的施加到无支撑的端部的重量计算。 在一些情况下，接口部件可以包括柔性电路。
