Miniature Electrodynamic Shakers
Miniature electrodynamic shakers are small, portable units designed to simplify your vibration testing needs. From the SmartShaker™ with an integrated amplifier, to an Inertial Shaker System for testing in hard-to-reach areas, mini shakers offer flexibility when testing. Miniature shaker systems range from 2 lbf (9 N) to 7 lbf (31 N) sine peak force excitation.

High Sensitivity ICP® Accelerometers
High sensitivity ICP® accelerometers are specifically designed to enable the detection of ultra-low-level, low-frequency vibrations associated with very large structures, foundations, and earth tremors. These sensors typically possess exceptional measurement resolution as the result of its comparatively larger size, which furnishes a stronger output signal and a lower noise floor. All units are hermetically sealed in a titanium or stainless steel housing. Models that include a 2-pin, military style connector provide the added benefit of being electrically case isolated for superior RF and EMI protection.

Miniature Piezoelectric Accelerometers
Structured with highly sensitive piezoceramic sensing elements, miniature Ceramic Shear ICP® Accelerometers have an excellent signal-to-noise ratio, high measurement resolution, and are ideal for conducting low-level vibration measurements. Due to their inherent higher sensitivity, a ceramic ICP® accelerometer can be assembled with a smaller mass than comparable quartz units, resulting in a sensor that is lighter in weight, has a higher frequency response, and has a lower noise floor. To further reduce the mass of the sensors, all ceramic shear accelerometers are housed in either tough, lightweight, laser-welded, hermetically sealed, titanium or aluminum housings. By minimizing the mass of the sensor, mass loading effects are reduced, which maximizes the accuracy of the data obtained.

Structural Test ICP® Accelerometers
Conventional structural test data systems use few to several hundred sensors. Cables bundles can be complex and confusing resulting in setup errors. Sensors with TEDS (Transducer Electronic Data Sheet) allow for an internal sensor digital chip to store sensor information. This information contains descriptive identifiers that when connected to a TEDS compatible signal conditioner or data system, reads the descriptive information and automatically aligns the data system. Human error is minimized, reducing time consuming data verification or re-test. The Series 333 ICP® accelerometers, and their accessories, are designed to address the needs of multi-point modal and structural test measurement applications. This equipment was developed in conjunction with the world renowned University of Cincinnati Structural Dynamics Research Laboratory and proven in real-world testing situations. The PCB 333 Series accelerometers delivers rapid system setup, reduces human documentation errors, maintains calibration data of each sensor, allows for “Plug-and-Play” installation, reduces overall test time lowering project test costs.

3-Component Quartz Force Rings And Links
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.

Miniature Quartz Force Sensors
Often the test engineer will try to take low level measurements with a sensors not rated for these low levels. Due to insufficient sensitivity the resulting data may be noisy, hard to analyze or unusable. Using the appropriately sized and ranged PCB Miniature Quartz Force Sensor solves the problem and gives reliable data at a Low Amplitude level. The miniature sensor configuration permits low-amplitude, dynamic compression, tension, and impact force measurements.
