Mining
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Heavy machinery is a common application for sensor technology.

LDS Laser USB Vibration Controller
Designed to generate a shaker drive signal and perform data measurements, the LDS® LASERUSB™ controller is typically used in R&D and production test applications, such as simulation of vibration and fatigue tests for automobiles, military vehicles, and ground transportation. It combines 24-bit precision with a wide dynamic control range and fast loop
Shock Response Spectrum Synthesis Vibration Control
SRS synthesis is used to evaluate the shock resistance of the DUT (device under test). This is achieved by synthesizing, within a closed-looped test system, a user-specified SRS profile of acceleration versus frequency in order to create complex transient waveforms for driving an electrodynamic shaker. The desired SRS profile is
Random-On-Random Vibration Control
Random-on-random (RoR) control simulates real-world complex vibration environments with a combination of a broadband random signal and one or more superimposed random narrow-bands. Both signal types are usually present simultaneously and the narrow-bands can appear at fixed frequencies or sweep over a predefined range. The overall random PSD (power spectral
Sine-On-Random Vibration Control
Sine-on-random (SoR) control simulates complex vibration environments with a combination of broadband random excitation and sinusoids or 'tones'. Generally, both signal types are present simultaneously and the tones may either appear at fixed frequencies or sweep over a frequency range. A typical example is the vibration from an automobile drive
Time Waveform Replication Vibration Control
Time waveform replication (TWR), also known as long time history (LTH), exactly replicates, in the laboratory, vibration environments using data obtained in the field. Field measurements, such as a vehicle’s road test or an aircraft flight run, can be imported into the host PC, compensated for suitability to the shaker
Resonance Search, Track And Dwell Vibration Control
Resonance search, track and dwell (RSTD) is an invaluable test for automated fatigue testing. A sine sweep is used to detect the resonant frequencies of the device under test (DUT). The test then dwells upon these frequencies for a specified period or number of cycles, automatically tracking changes in resonance
Transient Time History Vibration Control
Transient time history (TTH) allows the user to simulate real-world shock transients based upon actual field measurements. Transients are short-lived vibration events characterized by waveforms that start with relatively high amplitudes that quickly dampen out. Compensation can be applied to ensure the generated waveform is compatible with the target shaker
Classical Shock Vibration Control
Classical shock control creates a series of pulses to excite the device or structure under test, measures the structure’s response and performs a spectral analysis to determine its response and resonance characteristics. This type of testing profile offers higher accuracy and repeatability than regular drop-test methods. USE SCENARIOS Shock testing
Random Vibration Control
The random vibration (or excitation) test profile simultaneously excites all resonant frequencies of any given payload, thus it is well suited for product qualification tests and for characterizing a structure’s dynamics. A fast loop time is important for high accuracy, and so are multi-channel control, notching, and real-time analysis. USE
Sine Vibration Control
Sine control creates excitation with analog-quality drive signal and user-programmable sweep parameters. This test profile is particularly useful for studying the structural dynamics of the device under test, as it enables accurate measurement of dynamic response at resonances. Since sine control concentrates all the vibration energy at a single frequency,
