Description

Model QLA293 is a custom donut load cell that is designed to measure forces up to 20,000 lbs (~88.9 kN). It stands at a height of 1.530 in (38.86 mm), with an outer diameter of 4.48 in (113.8mm) and an ID of 2.13 in (54.10 mm). Constructed of 17-4 PH Stainless Steel, it is capable of operating in temperatures between – 40 to 185 °F (-40 to 85 °C). FUTEK can design custom donut load cells in various geometries and capacities. A common use for this style of load cell is to measure force of thrust bearings.
