DEWETRON Company ProfileFrom our founding in 1989, DEWETRON has become a market-leading provider of test and measurement systems. Our 200+ employees are located at our headquarters in Graz, Austria - and also in more than 25 countries around the world.

DEWETRON develops, manufactures, and distributes high-precision PC based systems with robust housings for por-table and laboratory use. The scalability, modularity and innovative platform technology of the hardware and software allow the systems to be deployed in almost all areas of research and development. Test and measurement engineers and technicians from many well known companies rely on our 20 years expertise. All over the world, around 230.000 measurement channels and more than 10.000 systems are in permanent operation in Automotive, Energy & Power, Aerospace & Defense, Transportation, as well as in General Test & Measurement applications. DEWETRON is part of the AUGUSTA Technologie AG located in Munich.

Automotive Power & Energy Aerospace Transportation General T & M

In shortest time to highest quality test and measurement dataDEWETRON systems help users to produce highest quality test and measurement data in shortest time. Both, our hardware and software are optimized to support this general target. How?

The hardware offers vastly different signal inputs like analog, digital, counter/encoder, video, GPS and various bus systems like CAN bus which are all recorded perfectly synchronized. Thus data analysis can be done very easily. Additionally a picture paints a thousand pieces of data. Of course sensor connection is matched to practical needs, that´s why we offer various connector options for most inputs.

The software contributes by its ease of use and powerful features. Setup of the amplifiers is a matter of a few clicks and sensors can either be automatically setup by TEDS or chosen from a sensor database. You can record as easily as pressing the STORE button, or as elaborately as having separate – even multiple – triggers on each input chan-nel. Once data are stored, press ANALYZE and you can replay it to the screen as easily as replaying a movie, with PLAY controls. Cursors can be used to zoom in and inspect specific areas of interest. In a matter of seconds nice looking reports can be printed. If you are using 3rd party analysis software you are also well served, export of the whole recording or just the interesting part to many different file formats is supported. So you can e.g. keep your Excel® spreadsheets.

Aerospace & Defense DEWETRON measurement units are a perfect fit for a wide range of complex tests required in aerospace and flight test. The rugged instruments are suitable for almost all kind of grounded and in-flight tests.

The ability to measure analog signals and channels pro-vided from the aircraft via ARINC or 1553 bus will help to understand the recorded data. Video, high speed video and or thermal imaging video can be recorded along with all other channels simultaneously.

The scalable instruments with various power supply options will give the user the possibility to operate it in different measurement tasks. Battery powered instru-ments can be operated independent from the aircrafts power grid. GPS synchronization of measured data will help to compare recorded and aircraft data afterwards.

Aerospace Application Examples

Modal TestModes are used as a simple and efficient means of characterizing resonant vibration; the majority of structures can be made to resonate. Resonances are determined by the material properties (mass, stiffness, and damping prop-erties), and boundary conditions of the struc-ture. Objects or structures are excited by a shaker according to its amplified input signal.

Distributed measurement system overview

Simultaneous data acquisition of air and ground data synchronized via GPS is controlled by the so called “Master client” – the administration center of the whole system used for setup and control operations and as the central data recorder. Modular client measurement systems can then be added to the measurement network via gigabit LAN. Additionally, multiple “View clients” are used to monitor data acquisition remotely.

Torsional and Rotational VibrationRotating machines and engines are sources of rotational and torsional vibration. Rotational vibration is a result of the change in shaft speed during one revolution and torsional vibration is due to angular twist in the shaft or drive train which may cause fatigue.

So you will observe: vibration, force, strain, voltage, current, power, CAN data and rotational- and torsional vibration with only one instrument at the same time.

That’s unique!

Setup For rotational vibration measurement one rpm sensor is used to determine the rpm deviation and for torsional vibration there is one at each end of the power train. DEWETRON supports a wide range of different sensors e.g. encoder, pickup, RIE-360/720 and many other sensors. All these are connected directly to a counter input of the DEWETRON system. Each counter input provides a power supply, three differential inputs with selectable trigger level compatible with all sensor outputs.

A ready to use template makes it easy to setup the measurement within a few minutes. Digital input filters, a sensor database and a reference curve eliminates sensor errors.

Various output channels are immediately provided for further investigation:

Reference angle [deg]

Modal Analysis is needed in every modern construction. The measurement of system parameters, called modal parameters, are essential to predict the behavior of a structure.

These modal parameters are needed also for mathe-matical models. Parameters like resonant frequency(s), structural damping, and mode shapes are experimen-tally measured and calculated.

DEWETRON provides a hard and software solution which is adapted to your application. Starting up from 8 chan-nels used for maintenance, service and troubleshooting till up to 1000 channels used for complex structures.

The easy-to-use software is suitable for professional and occasional users.

OverviewTo measure a FRF of a structure basically two channels are needed. One channel is used to measure the excitation force, which could be an Impact hammer or a shaker. This excitation force excites the structure, and at least one acceleration sensor measures the response of the structure. Out of that the transfer characteristic (FRF) and the modal parameters are calculated. To determine the structure you have to measure several points to get the whole system identified. This could be done either with one response or up to hundred or thousand channels depending on the complexity of the structure.

Channel SetupIn the channel setup the excitation-, and the response channels are defined. DEWETRON amplifiers support the state of the art TEDs interface which gives the maximum comfort especially at high channel count.

The FRF Setup provides all parameters needed for the measurement

Free run, triggered mode

Also the channel definition according to structure is done in the FRF setup. A struc-ture could be imported from any other software with unv. file format or created with the included geometry edi-tor.

Measurement

The prepared measurement screen will give you all the control possibilities for either running or triggered FRF.

The tool bar provides all important and necessary functions which are needed during the measurement. At Single Input Single Output (SISO) measurement either the excitation or the response could be moved, because sometimes it is easier to move the excitation than the response. DEWETRON supports both types of this measurement.

Analysis In the analyze screen the FRF spectra are shown together with the geometry.

The included analyze tools like

animation of the geometry,

Circle Fit,

MIF

are provided to determine the results immediately.

In case of an error the spectrum could be re-measured immediately. This saves time and money. Display options could be set according to the needs, Phase, Coherence, Re-, Imag, are only a few possibilities which could be set.

FRF ExportFor further investigation and analyses in modal packages like ME-Scope the FRF data, coherence and excitation can be exported to the UFF (Universal File Format) – or simply copied to clipboard – and used in standard applications like Microsoft Excel or Word.

Function Generator For a running FRF the structure is excited with a shaker. Here either one shaker or multiple shakers for big structures are used. The shaker(s) have to be controlled mainly in ampli-tude, phase, waveform and frequency. DEWESoft offers an integrated function generator up to 16 Channels which is fully software controlled.

Various time patterns like

Shock Response Spectrum (SRS)The shock response spectrum shows the maximum responses of a series of uniformly damped single-degree-of-freedom (SDOF) systems caused by a shock waveform applied on the structure. After setting damp-ing, resolution (12,24,48,96/octave) and primary section the spectra are calculated out of the time domain sig-nals.

The time domain signals are recorded with DEWESoft and exported to FlexPro.A pre-pared SRS-Script with user interface supports a conve-nient straight forward proce-dure for fast results.

Order TrackingKey Features

EASY TO SETUP

Analysis of rotating machines under operational con-ditions requires specialized methods, such as order tracking. Compared to the standard FFT calculation, the spectrum is based on orders instead of frequency. Orders describe the fundamental frequency of the actual rotation speed [Hz] and its multiples. With this method frequency components are separated into either engine-speed related or structure related ones, showing problematic areas when overlapping.

DEWETRON provides a powerful and very easy to use order tracking module for fast and efficient results. The data and the rpm information is recorded simultaneously in time domain and re-sampled in the order tracking mod¬ule. Therefore we can show narrow band FFT, waterfall spectra, and still keep all other convenient functions in time domain.

Overview Order tracking requires two signals, the vibra-tion signal and the rpm information. The mea-surement is done in time domain, and all the order related channels are calculated out of these time signals.

A fast state of the art re-sampling method pro-duces the results online. Run-ups, coast-down or both are possible online.

Time based data recording enables recalcula-tion even in post processing. Narrow band FFT, CPB spectrum and order tracking information could be shown at the same test run, saving time.

BalancingRotating machines and engines produce vibration from many sources, including torsional and rotational vibra-tion. Also unbalanced rotating parts are sources for vibration. Unbalanced masses are distributed by the rotor causing vibration. To balance a system, we have to mea-sure and correct the masses so that the rotor is returned to a balanced condition.

DEWETRON provides an easy to use and straight-forward tool for single and dual plane balancing. This add-on is included as an option in every DEWETRON instrument. One or two acceleration sensors and a tacho probe are needed.

GeneralDuring construction or assembly of a machine or even through abrasion, a rotor could become unbalanced. This condition causes vibration, noise and fatigue of the material.

DEWETRON provides an in-field-balancing method, which enables balancing of the machine. This saves time and money because balancing can be done in situ and the rotor is balanced in its operating condition, which includes the whole structure of the machine.

Balancing includes in general five steps:

1. Measuring the imbalance

2. Add a trial mass

3. Add the correction mass (balancing)

4. Measuring the balanced system

5. Repeat steps 2 to 4 if needed

Balancing is done either for one plane or two planes. One plane is used for small rotors, where two plane is used for long rotors.

For this measurement one or two acceleration sensors (1 plane 2 plane) and a tacho input are needed. The acceleration signals are recalcu-lated into velocity and used in the order track-ing module together with the rpm channel to extract the first harmonic and phase.

The prepared balancing template in DEWESoft provides step by step guide through the whole balancing pro-cedure.

Multiple templates linked together!

If a triaxial sensor is used, the balancing can be done on x and y direction of the plane(s) at the same time. Depending where you get the best result (x or y direction) you choose the correction mass. This saves time and guarantees a high quality of balancing.

ACADEMY

CalibrationDEWETRON maintains two top-notch calibration facilities with the same equipment: one at our worldwide headquarters in Austria, and another one at DEWETRON USA in Rhode Island. Our cal lab is based on the Fluke 5500 series calibrator, and we run the METCAL calibration system, which allows us to automate nearly every process.

For customers running their own calibration lab we offer a calibration hardware kit (CAL-KIT) and METCAL

software procedures.

TrainingTraining is offered on demand or at regular intervals. We run training centers at DEWETRON Ges.m.b.H in Graz/Austria and at DEWETRON Inc. located in Rhode Island, USA. At both locations there is a nice training facility and class sizes are limited in order to preserve the quality of the presentation. Engineers and technicians from many well-known companies participated our classes.

The trainings help users to stay up to date on the latest enhancements and updates as well as become more effective utilizing their DEWETRON systems. The train-ings cover effectively using the DEWETRON hardware with DEWESoft software for a wide range of mea-surement applications. Sub-topics include instrument setup, sensor connection as well as digging into math modules, triggers, filtering, shock, vibe, pressure, dis-placement, stress, strain, video, GPS and more.

Of course onsite training is offered, too.

DEWE-ACADEMYIn the DEWE-ACADEMY single or multi-day events are offered. We teach the practical application of our measurement systems, based on the relevant theory. The seminars cover various application areas for engineers with different levels of knowledge - from “newbie” to “expert”. Practical exercises and high interac-tivity with the trainers ensure the lasting learning success and the suitability for daily use. The course language is GERMAN and courses take place in Austria or Germany. For English courses please contact us directly.
