Abstract: A multi-dimensional strain sensor for measuring the strain forces on a drawbar or other load bearing member. The strain sensor is used in conjunction with a load bearing member having a top surface, a bottom surface, a left surface and a right surface. The strain sensor has a four strain gauge pairs, each located on the top, bottom, right and left surfaces. The gauges are configured to output voltage relative to strain placed on them. The outputs from the four gauges are amplified. The outputs from the top and bottom gauges are then input to a differential amplifier in order to determine vertical load. The outputs from the right and left gauges are input to a differential amplifier to determine side load. The sum of the top and bottom gauges and the sum of the left and right gauges are input to a differential amplifier to determine draft load. An analog to digital converter is coupled to the gain amplifiers in order to zero the gauges.
