DEWESoft - Model SIRIUS -USB and EtherCAT Data Acquisition System

The SIRIUS data acquisition system is designed to be flexible, modular, expandable, and secure. The main goal of the development of SIRIUS was to create a simple to use device that prevents frequent errors during the measurement process.

SIRIUS offers virtually unlimited configuration possibilities. Slices are available from 1 to 16 analog channel configurations and can be daisy-chained together to extend channel count. An array of different analog amplifiers are available to give you the possibility to connect virtually any sensor. 

Technologies like DualCoreADC^®, SUPERCOUNTERS^®, high isolation, and innovations of Dewesoft X3 software make SIRIUS the most unique data acquisition solution on the market today.

Using SIRIUS does not require any complex configuration setups or programming.

With plug and play functionality, smart sensors, and advanced TEDS support, making measurements with SIRIUS are easier than riding a bike. You will get it right the first time and you will be ready to measure in no time.

Getting precise and graphically rich results is easier than ever. Just drag and drop one of the many flexible visual displays and connect them to your channels. Voila! It works like magic.

The DualCoreADC^® technology solves often faced problems with signal measurement - input overload, noise, and artificial frequencies in the signal caused by aliasing. The input signal can be higher than expected (out-of-range) and therefore clipped by the ADC. This will result in an incorrect measurement and you will have to repeat the test all over again.

DualCoreADC^® technology prevents these problems. Each channel amplifier has two ADC`s that always measure the high and low gain of the input signal. This results in the full possible measuring range of the sensor and prevents the signal from being clipped. 

With DualCoreADC^® technology SIRIUS achieves more than 130 dB signal to noise ratio and more than 160 dB in dynamic range. This is 20 times better than 24-bit systems and 20 times less noise.

SIRIUS instrument comes with high galvanic channel-to-channel, channel-to-ground isolation (±1000 V), and even includes isolated sensor excitation.

With such isolation, we have no problem measuring high voltage potentials and no problem with common mode voltages. We are also safe with measurements like vibrations, temperatures, or any other measurement where non-isolated sensors are placed next to the high voltage potential against the DAQ system ground. In such cases, a non-isolated DAQ system would burn or at least give faulty wrong results. With SIRIUS it is just one thing less to worry about.

Digital isolation has another big advantage - preserving frequency bandwidth of the amplifiers. SIRIUS provides "worry-free" measurements, less noise, no ground loops, and the best possible signal quality.

For less demanding applications and lower cost, SIRIUS is also available with only channel-power supply isolation, without channel-channel isolation.

SIRIUS utilizes a patented technology called SUPERCOUNTER^® in every of its counter/encoder inputs.

Counter inputs can measure 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), SUPERCOUNTERs^® are able to extract the 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 SUPERCOUNTERs^® work on a 102.4 MHz time base, independent from the current sampling rate.

Counter inputs are fully synchronized with analog, CAN bus, and other data sources to enable easy applications like balancing, order tracking, and torsional vibrations.

For more information on our SUPERCOUNTER^® inputs please navigate to Digital Counter PRO training course.

SIRIUS slices can optinally be configured with 8 analog output channels on the backplane. Analog outputs can have four functions:

• Multi-channel function generator (software option upgrade required)
• Stand-alone signal conditioning
• Control channels
• Analog file replay

Output Oversampling

Similar to the Sigma-Delta converter on the input the analog output uses a special oversampling technology which enables higher frequencies to be put out correctly. Although the maximum SIRIUS sampling rate is 200 kHz the output looks like sampled with 1 MHz.

SIRIUS hardware is capable of reading different signals like voltage, strain, ICP/IEPE, charge, CAN, counter, encoder, and digital. Additionally with the included Dewesoft X3 software, you can easily acquire and combine data from additional interfaces like GPS, Flexray, 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 this thanks to our timing and GPS synchronization technologies. 

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

SIRIUS slices can be used as a stand-alone DAQ units or stacked and daisy chained together into larger channel count system with simple click-mechanism.

With the EtherCAT interface SIRIUS slices can be distributed and placed close to the sensors to increase signal quality. Only one cable is required for data, power and sync between each SIRIUS device and can span up to 100 meters between nodes.

The configuration for working with multiple instruments is as easy as working with single unit.

SIRIUS slices are also available in more rugged fanless chassis enclosure without any cooling fans ready for measurement applications in heavy industrial, dust environment. 

All fanless SIRIUS slices are IP50 rated and completely dust protected. 

For even more rugged, IP67 waterproof version, take a look at SIRIUS waterproof DAQ system.

SIRIUS ACC input for IEPE sensors has a LED ring around the connector. When a sensor is connected SIRIUS will constantly check current flow to the sensor and will turn the LED bright green or bright red, depending if the sensor`s impedance is okay.

This way you have immediate visual feedback if all your IEPE sensors or wiring is correct. This is just another small but very useful detail that makes your life as a test engineer a little bit easier.

SIRIUS modular slices are available in fully isolated (1000V galvanic channel-to-channel and channel-to ground isolation) or differential version. Each slice can be delivered with one of the standard front-end options or you can freely select amplifier and connector for each of the eight available channel slots (see top slice on the left image).

Some amplifiers have additional option to choose from multiple connector types. For larger projects, we can develop a custom connector type.
