Bestech Australia have presented the model 3417/3497 single ended shear beam load cell from BCM Sensors. These are low-profile, high precision load cells based on the shear-beam working principle.
This load cell can find applications in hopper scales and platform scales, or can be used to measure beam bending loads. The rated capacities of the load cells range from 500 to 2000kg, and the rated output is 2.0±0.005 mV/V.
The combined error (accuracy) is a very low 0.02% of the full scale, useful for high precision measurements. These low profile load cells have a safe overload limit of 1.5 times the full scale range, and have a compensated temperature range from -10°C to 55°C.
Excitation is recommended at 10V DC, although voltages up to 15V can be used. This 3417 load cell is made from alloy steel, which has a nickel plated treatment, while the 3497 is constructed from stainless steel. Both give protection up to a rating of IP66, and are easy to install and replace.
