Load pins

The 5719/5799 model double-ended shear-beam load pins from BCM Sensor Technologies are made from either alloy steel (5719) or stainless steel (5799) and sealed to IP66 or IP67 protection grade, depending on application conditions.

The sensing elements of these 57-series load pins are BCM strain gauges, developed from their advanced metal foil technology. These strain gauges form a Wheatstone bridge to sense the deformation of the load pin, this deformation resulting from the three forces which act vertically to the axis of the load pin. The load pin is operated on the double-ended shear-beam principle, where the middle part of the shaft has a shearing shift relative to the two sides of the shaft. The 5719/5799 load pin can be used as traction force sensors (draft sensors) to be installed in crane, hopper, process and onboard vehicle systems to measure the concerned force.

The BCM 5719/5799 load pins can measure forces ranging from 20 to 800 kN and have high accuracy, up to 0.2% FSO. The output signal can be amplified and configured to either a 4-20 mA current signal or 0.5-5 V/0.5-10 V voltages on request. The BCM 5719/5799 load pin is compact and rigid in construction, which makes it easy to be installed or replaced in the installation position.
