Three-component dynamic force sensors are offered in both ICP® and charge output configurations for dynamic and quasi-static force measurement applications. Each utilizes an array of precision-aligned, quartz sensing crystals. Measurements along the z-axis are proportional to applied compression, tension and impact forces. Measurements along the x- and y-axes are proportional to shear forces that are imposed upon preloaded crystals by the test fixture.

ICP® styles contain built-in, microelectronic signal conditioning circuitry to provide clean, low-impedance output signals that can be transmitted over low cost cables and in adverse, industrial environments. Multi-pin connectors facilitate a single point hookup with common, multi-conductor cable. Charge output styles achieve higher temperature operation and are suitable for applications requiring flexible setup and maximum signal-to-noise.

A common use of three-component force sensors is Force Limited Vibration (FLV) testing. This is an alternative test method that improves the vibration testing approach based on measuring and limiting reaction force between shaker and test item. By using this method, the acceleration input to the test item is automatically notched at the equipment resonances by limiting shaker force values to those predicted for actual flight.
