The F341 thru F347 are suitable for use in material testing machines, airframe test fixtures, and any application requiring a load cell that has a low profile, a high degree of stiffness, fatigue rating, and resistance to the negative effects of extraneous forces. For universal or tension only applications, the F341 thru F347 are usually bolted to a surface or plate that is flat and parallel within ±0.0002 inch. For compression only applications, a load button with a spherical loading surface and with threads that will engage the threads found in the center-loading hole of the F341 thru F347 should be used. The F341 thru F347 can be used with AC carrier and DC strain gage signal conditioning electronics. Tension plates, spherical load buttons, and interconnecting cable assemblies are available as options. SensorData will provide in-house calibration of the F341 thru F347 with customer-supplied electronics for a fee.

(2) With load centered, maximum load that can be applied without producing a permanent shift in performance characteristics.
(3) With load centered, maximum load that can be applied without physical damage.

It is recommended that the F341 thru F347 be mounted on the optional tension plate available from SensorData. If this is not practical, the F341 thru F347 should be mounted on a surface flat to 0.0002 inch and rigid enough not to deform under a load equal to 100% of load cell’s rated capacity. Mounting bolts should be grade 8 or better. Request FAQ 9907/Q053 for a copy of Installation Information that applies to SensorData Shear Web Load Cells.
