The F312 is 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 F312 is 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 F312 should be used. The F312 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 F312 with customer-supplied electronics for a fee.
