PCB’s Triaxial Force Sensors Designed for Aerospace Vibration Testing

The 261A Series Triaxial Force Link Sensors from the Force/Torque Division of PCB Piezotronics Inc. simultaneously measures dynamic and quasi-static forces in three orthoganal directions (X, Y and Z-axes). The sensors are used during vibration testing of aerospace structures to match the mechanical impedance of shaker inputs and may be used to force limit the shaker cotnroller to prevent structure damage. Additional applications include cutting tool monitoring, biomechanics feedback and automobile chassis dynamics. Series 261A comes preloaded between two plates with a four-screw mounting pattern to allow easier installation and features full scale measuring ranges from 500-4,000 lbs. in the X and Y directions and from 1,000 to 10,000 lbs. in the Z direction.
