8-Channel USB Data Acquisition (DAQ) System DEWE-43A

Award-winning and versatile 8-channel USB data acquisition system with unmatched price/performance ratio and hand-size footprint. 8 universal analog inputs, 8 digital/counter/encoder inputs, and two high-speed CAN bus inputs.

Description

Universal Analog Inputs

Truly universal analog inputs are available that can accept voltage, IEPE, full/half/quarter bridge, RTD, and resistance signals natively. Additional input modes such as charge, thermocouple, RTD, current, and LVDT signals are supported via our DSI adapters.

24-Bit Sigma Delta ADC

DEWE-43A is equipped with 24-bit sigma-delta analog-to-digital converters with an anti-aliasing filter. The analog sampling rate is software selectable up to 200 kS/s per channel.

Sensor Power Supply

Each analog channel on the DEWE-43A provides power for sensor excitation.

SuperCounter® Inputs

Each counter channel input is capable of three digital inputs, one event counter, encoder, period, pulse-width, duty-cycle, and precise frequency and angle measurement using patented SuperCounter® technology.

Isolated CAN Inputs

DEWE-43A includes two high-speed CAN 2.0b channels with 1 Mbit/sec data throughput. Both ports offer additional support for CCP, OBDII, J1939, and CAN output.

Fully Synchronized

All SIRIUS input channels – analog, digital, or CAN – are fully synchronized with microsecond accuracy. Multiple SIRIUS devices can be daisy-chained and synchronized together with the same pin-point synchronization accuracy.

Isolated Power Supply

DEWE-43A power supply is internally isolated which is eliminating the possibility of ground loops.

Software included

Every Dewesoft data acquisition system is bundled with award-winning DewesoftX data acquisition software. The software is easy to use but very rich and deep in functionality. All software updates are free forever with no hidden licensing or yearly maintenance fees.

Dewesoft quality and 7-year warranty
Enjoy our industry-leading 7-year warranty. Our data acquisition systems are made in Europe, utilizing only the highest build quality standards. We offer free and customer-focused technical support. Your investment into the Dewesoft solutions is protected for years ahead.

Reliable Data Acquisition System

DEWE-43A weighs under two pounds and is small enough to fit in your hand. And yet inside this small box beats the heart of a giant.

When you need an instrument with stellar specifications, and yet with a budget-friendly price tag, DEWE-43A will not let you down.

But don’t get confused by a great price. The build quality is not compromised. We carefully design our instruments and CNC every unit out of a solid block of aluminum. This way, the instrument is not only tough but also light for maximum portability.

DEWE-43A is an ideal solution for various dynamic data acquisition applications. It will help you solve the most demanding test and measurement challenges. It is used around the world and really proven to be a Swiss Army Knife for every test and measurement engineer.

Intuitive and easy to use

Using Dewesoft data acquisition systems does not require any complex configuration setups or programming knowledge. We also kept this in mind when designing SIRIUS® XHS.

Plug-and-play technology with smart sensors and advanced TEDS is supported by default. This makes performing measurements with the Dewesoft DAQ systems easier than riding a bike. You will be ready to measure in no time.

Getting precise and graphically rich results is easier than ever. The drag-and-drop user interface of bundled DewesoftX software will allow you to define your measurement screens and results in no time. A rich mathematics library for signal processing is also available one click away. Just connect the right widget with your input channel and Voila! Works like magic.

SuperCounters®: precise speed and angle measurement with counter and encoder sensors

Dewesoft data acquisition systems utilize a patented and registered trademark technology called SuperCounter®.

Counter inputs can measure the RPM and angle of rotating machines. In comparison to standard counters, which only output integer numbers one sample later (e.g. 1, 1, 2, 2, 3, 4), the Dewesoft SuperCounter inputs are able to extract accurate values like 1.37, 1.87, 2.37, etc. fully synchronized for time and amplitude.

This is done by measuring the exact time of the rising edge of the signal with an additional counter. Our SuperCounter inputs work on a 102.4 MHz time base, independent of the current analog sampling rate.

Synchronization

DEWE-43A data acquisition hardware is capable to acquire different signals like analog, CAN, counter, encoder, and digital. With the power of included DewesoftX software, you can easily acquire and combine data from additional interfaces like GPS, Flexray, XCP, Ethernet, Serial, PCM telemetry, and many more.

Even though each data source can have different sampling rates, all your data will be perfectly synchronized down to microsecond accuracy. All these thanks to our different supporting timing and GPS synchronization technologies.

Synchronized video can be added for free. Dewesoft includes A powerful video engine and has support for simple DirectX web cameras, high-speed video cameras that are fully synced to analog data, and also 3rd party thermal cameras.

Expand Channel Count

If the channel count on one DEWE-43A DAQ instrument is not enough our flexible design allows you to easily extend channels at any time.

You can either synchronize multiple DEWE-43A instruments together or extend input channel count with any of our other DAQ systems such as SIRIUS or KRYPTON, or even navigational instruments or CAN interfaces.

The configuration for working with multiple instruments is as easy as working with a single unit and thanks to synchronization technologies (internal or external IRIG, GPS) data will always be perfectly synchronized.
