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.

Columbia Research Laboratories
The force balance accelerometer has a classical critically-damped, second-order frequency response. There is no peaking in the response but simply a smooth roll-off above the natural frequency. This property along with the excellent characteristics of the "HP" torquer design makes Columbia accelerometers the best choice for demanding applications where precise DC and near-DC measurements are needed in demanding shock and wide band vibration environments. Columbia force balance accelerometers are available to cover virtually all applications. Low noise, high output units can be used for seismic structure motion studies while miniature, high range versions are optimum for measuring more violent high G environments encountered in many industrial, aircraft and missile applications.

Quantum Accelerometer
-
A quantum accelerometer uses atom interferometry to measure accelerations along a horizontal axis. Quantum accelerometers are able to achieve a combination of sensitivity and stability by exploiting quantum interference. As such, they will be critical components of a quantum inertial navigation unit, which will offer satellite-free navigation with unparalleled long-term accuracy. A phase locked SolsTiS system underpins this setup and provides the extremely low phase noise required to make high sensitivity measurements and dynamic frequency tunability to address multiple atomic transitions.

Advanced Seismic Source
GI-SOURCE
-
Sercel developed the GI-SOURCE to reduce and suppress the bubble oscillation from a single impulsive source to simplify processing. The GI-SOURCE impulsive source is based on the same technology as the GI-SOURCE but is different in that it has two independent air chambers within the same casing : the Generator (generating the primary pulse and creating the main bubble) and the Injector (injecting air inside the main bubble so that it collapses quickly).

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.

Endevco Cryogenic Charge Output Accelerometers
-
PCB's acquisition of Endevco's full line of testing sensors means all Endevco sensors are now backed by PCB's Total Customer Satisfaction (TCS) guarantee. Endevco® cryogenic piezoelectric accelerometers are built specifically for measuring vibration under cryogenic conditions down to -452° F (-269° C). Signal outputs of these units are very stable even at extremely low temperatures. Their rugged internal construction is designed to withstand multiple cycles of thermal shock with steep temperature gradient. The accelerometers are self-generating devices that require no external power source for operation and contain no electronics. This allows them to operate below the -320° F (-196° C) limit of ICP accelerometers, down to -452° F (-269° C).

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.

Seismic Sensors & Transducers
-
Displacement Pickups are vibration transducers that incorporate a spring-mass system with eddy-current damping using a frictionless pivot. This pivot is a spring flexure that serves as the ‘spring’ and a moment arm attached to the pivot serves as the ‘mass’, which allows resolutions down to the micro inch range. At frequencies above 50Hz, the mass remains fixed in space and becomes an inertial reference.
