3-Component Quartz Force Links 261 Series

Three-component force links eliminate the preload requirement of 3-component quartz force ring sensors, and offers a convenient, 4-screw hole mounting plate on each side end the sensor. Quartz 3-component force links are constructed by installing a 3-component force ring sensor, under preload, between two mounting plates.

An elastic, beryllium-copper stud holds the stainless steel assembly together. This elastic stud permits the applied force to be sensed by the crystals with a minimal amount of shunted force. The stud also provides the necessary normal force, and the friction required to transmit shear forces in the x- and y-axes. Since 3-component force links are factory preloaded, they may be used directly for measurement of compression and tension in the z-axis, and positive and negative forces in the x- and y-axes.

Versions are available with ranges up to 10k lb (45k N) in the z-axis (perpendicular to the top surface), and up to 4000 lb (18k N) in the x- and y-axes.
