Solutions for Dynamic Signal Analysis applications
The Dewesoft X software can acquire signals simultaneously from different sources (even with different sampling rates). It includes rich post-processing features with all the powerful mathematics and analysis functions for various application needs.
The DEWESoft amplifiers on the analogue front-end build the solid base to convert any physical input (strain, acceleration, force, temperature, current, ...) into accurate digital signals for the software.
All other signals such as digital, counter, CAN bus, video data, serial interface... are acquired fully synchronised. DEWESoft always stores the raw signals!
The channels arrive on the digital »backbone«, where they can be used for further mathematical calculations (filtering, statistics) and in modules such as Torsional Vibration, Order tracking, Sound Level... The math results can be used as input for other modules and vice versa! Calculations in realtime, as well as on stored data.
The results can then be linked to powerful, configurable instruments (like Digital meter, Analogue meter, Recorder, Scope, FFT, XY graph, Orbit plot, 3D graph...) with lots of properties.
Very often the math modules provide specialised instruments, which results in a turn-key solution for a range of applications.

We offer complete line of powerful, rugged and very flexible DAQ instruments for any automotive-based application. Either modular and distributed design with external computer or all-in-one design with built-in display and industrial-proof rugged computer. For testing in extreme environments we also offer fully sealed, water, dust and shock proof line of IP67 rated instruments.
High dynamicThis new technology solves the often faced problem that the signal is higher then expected and therefore clipped. DEWESoft® DUAL CORE ADC technology always gives you the full possible measuring range, because the signal is measured with a hight and low gain at the same time!
Customisable front-endSelect your amplifier configuration. From the image example above:
IEPE sensor checkThe LED ring around the connector will light green or red, depending if sensor impedance is ok.
Fully IsolatedThe worry free solution provides isolation on the sensor side (channel to GND, as well as, channel-to-channel) and even isolated sensor excitation! Less noise, no ground loops, best signal quality.
Super-countersTo achieve highest accuracy, DEWESoft uses a special technology to determine the count and exact time of the input edge on a 102 MHz timebase. This allows the usage even for most demanding applications such as torsional vibration.

Vibration can be considered to be the oscillation or repetitive motion of an object around an equilibrium position. Vibrations usually occur because of the dynamic effects of manufacturing tolerances, clearances, rolling and rubbing contact between machine parts and out-of-balance forces in rotating and reciprocating members.View course Take quiz
Spectral analysis using the FFT
Frequency analysis is just another way of looking at the same data. Instead of observing the data in the time domain, frequency analysis decomposes time data in the series of sinus waves. Fast Fourier transform is a mathematical method for transforming a function of time into a function of frequency.View course Take quiz
Modal testing (FRF)
Modal test and analysis are used to determine the engineering structures modal parameters, such as modal frequencies, damping ratios, and mode shapes. The measured excitation and response (or only response) data are utilized in modal analysis, and then dynamic signal analysis and modal parameters identification are processed.View course Take quiz
Order tracking method is used to extract the harmonic components related to the rotational frequency of the machine. Order tracking is used is the analysis of vibration signals from rotating machines. There we use order spectrum instead of the frequency spectrum. An order spectrum gives the amplitude and the phase of the signal as a function of the harmonic order of the rotation frequency.View course Take quiz
Human vibration is defined as the effect of mechanical vibration of the environment on the human body. During our normal daily life, we are exposed to various sources of vibration, for example, in buses, trains, cars. Many people are also exposed to other vibrations during their working day. Those vibrations have to be monitored and are defined by standards.View course Take quiz
Rotational and torsional vibration
Torsional vibrations are important whenever power needs to be transmitted using a rotating shaft or couplings, such as in the case of automotive, truck and bus drivelines, recreation vehicles, marine drivelines or power-generation turbines. Torsional vibrations are angular vibrations of an object and rotational vibration is simply the dynamic component of the rotational speed.View course Take quiz
Balanced rotors are essential for most kinds of rotating machinery. Unbalance will create high vibrations, reducing fatigue life, causing material defects. In most cases the rotor unbalance is the major problem of vibration, it is related to the rotational frequency. The goal of balancing is to minimize vibrations related to the first order.View course Take quiz
Fatigue is the progressive and localized structural damage that occurs when a material is subjected to cyclic loading. Continued cycling of high-stress concentrations may eventually cause a crack which propagates and results in leakages. This failure mechanism is called fatigue.View course Take quiz
