Small USB box provides plug-in modules, 200 kS/s and isolation8/2/2010 - Wakefield, RI;FOR IMMEDIATE RELEASE:
The DEWE-50-USB2-8 brings unprecedented power to USB data acquisition
There are a lot of USB based data acquisition instruments on the market today, but few of them provide real galvanic isolation of the input signals. Isolation is essential to protecting the test engineer and equipment from the effects of ground loops and high common mode voltages.
Most of the new crop of USB boxes emphasize low cost and convenience, but they achieve this by skipping real signal conditioning for serious data acquisition applications.
The DEWE-50-USB2-8 from Dewetron changes this completely, taking a fresh approach to USB data acquisition, incorporating real plug-in signal conditioning modules for low and high voltages, strain,
pressure, acceleration, sound, temperature, force, and more.
The DAQP-HV high voltage module, for example, has selectable input ranges from ±20V to ±1400V (AC or DC), has a bandwidth of 300 kHz, and real galvanic isolation of 1800 Vrms. Therefore it can be used in demanding high voltage environments safely and with excellent performance. With this kind of isolation the test engineer can forget about CMV and focus on making the measurement.
The DEWE-50-USB2-8 has a powerful digitizer inside which features eight separate 24-bit ADCs - one per analog channel, for simultaneous sampling of all channels with very high resolution on the vertical axis. 24-bit resolution provides the test engineer the luxury of such a high dynamic range that he or she can use a single gain setting for a widely varying signals, and still get great resolution recordings.
Any combination of 8 DAQP series plug-in modules plug into the front of the small DEWE-50-USB2-8 box, while the rear panel provides several more inputs:
• Two synchronous counter inputs, which can handle a wide variety of encoders and tachometers
• Each counter can alternatively be used as three digital inputs, for recording multiple bi-state TTL “event” inputs
• Two high speed CAN BUS interfaces, so that you can connect up to the data buses in all kinds of cars, trucks, aircraft, trains, and more. Everything is recorded synchronously to a single data file within DEWESoft
The rear panel also contains the DC power input connector, because the system runs from 10-30 VDC directly (AC/DC adapter and line cord is included). (more…)
There is also a locking USB connector, of Dewetron’s own design, so that it cannot be pulled out of the chassis by accident.
Conditioned analog outputs from the inputs are also available as an option, so you can access ±5V outputs from each of them.

Countless uses...
Power plants, flight test, train testing, automotive testing, factory trouble-shooting...
Power plant testingFrom rod control and rod drop testing in nuclear plants, to walk-around trouble-shooting in a wide variety of applications. Advanced uses: 1-phase and 3-phase - all power quality properties are calculated in real time and displayed graphically. Easy report generation.
Flight testAdd ARINC 429 and MIL-STD-1553 interfaces, as well as IRIG time code and PCM data inputs to this Dewetron system, creating a powerful flight test data acquisition recorder.
Train testNew car inspection, speed tests, braking and emergency braking applications, using GPS, video and other speedometer sensors.
Automotive testDrivability, Road load testing, CAPS and related applications, pass-by noise tests, and all manner of in-vehicle and test cell applications.
Factory trouble-shootingMachine diagnosis, shock and vibration testing, thermovac chambers, and hundreds of physical measurement test and measurement applications.
Channel ExpansionYou can also plug in a second DEWE-50-
USB2-8 to this one using the SYNC and USB DEVICE interface.
The system runs from 9-36 VDC power, and a convenient AC/DC converter is included so that you can power the system from standard 120 VAC or 240 VAC power.
Plug-in ModulesThere are DAQ series plug-in modules
available which can handle a wide variety of sensors, including the DAQP-STG, developed by Dewetron for NASA, who have more than 1000 of these modules. The DAQP-STG can handle any kind of DC strain gage, voltages, resistive and ohmic measurements natively, and with the addition of our MSI plug-in interfaces, can additionally handle IEPE accels and mics, charge sensors, 200V, and more. This module has a bandwidth of 300 kHz.
If you don’t need such high performance, a lower cost version is available called the DAQP-MULTI, which can directly handle bridge, resistance, thermocouples, and RTDs, at a more attractive cost per channel.
The DAQP-HV is a high voltage module with ranges up to ±1400V, and the DAQP-LV low/medium voltage module with ranges from ±10 mV to ±50V, and still with high isolation.
The DAQP-ACC-A is a 300 kHz bandwidth IEPE (ICP) signal conditioner amplifier which powers microphones and accelerometers.
Of course, CHARGE sensors are also supported with the DAQP-CHARGE-A and -B modules.
Several other DAQP series modules are available for frequency to voltage, and other kinds of sensors.
Great SoftwareWhen you install the DEWE-50-USB2-8
on your computer, in addition to the driver, Dewetron’s award winning DEWESoft data acquisition software will be installed.
DEWESoft provides incredible graphical control over the user interface, from system setup through screen design, acquisition, triggering, and replay.

In a class by itselfVersion 7 now includes many more capabilities in the analysis
mode. Data files can be processed using a wide range of math functions, from programmable filtering, (statistical analysis, integration and differentiation, and much more.
Standard displays include strip chart recorder, scope, digital and analog meters, FFT, and tabular numeric displays.
You can connect video cameras to your computer and record video in sync with the data, adding a whole new level of understanding to it.
Software options are available for 3-phase power quality analysis, modal analysis, sine processing order tracking, torsional vibration, sound level meter, and many more advanced capabilities.
Price/size/performance Instruments like the DEWE-50-USB2-8 are commonly sold at a
much higher price point due to their isolation, 200 kS/s/ch sample
rate, and 24-bit resolution.
Instruments like this are usually also much larger and occupy a
bigger footprint than the DEWE-50-USB2-8.
With this model Dewetron has put a high quality data acquisition
within every engineer’s reach.
The DEWE-50-USB2-8 costs $7500 plus your choice of DAQP
series plugin modules. DEWESoft data acquisition and analysis
software is included at no additional cost with this model.
Deliveries are available within 4-6 weeks after order, and the
product has been shipping since May 2010.
