Next Generation DAQ System

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

SIRIUS offers virtually unlimited configuration possibilities. SIRIUS slices are available in 1 or 16 analog input channel configurations. The slices can be daisy-chained together to extend channel count. An array of different analog amplifiers are available for signal conditioning to give you the possibility to connect virtually any sensor type

Technologies like DualCoreADC®, SuperCounters®, high galvanic isolation, and all the software innovations of the award-winning DewesoftX software make SIRIUS the most unique data acquisition solution on the market today.

Next Generation DAQ System

Very Intuitive and Easy to Use

Using SIRIUS data acquisition systems does not require any complex configuration setups or programming knowledge.

Plug-and-play technology with smart sensors, and advanced TEDS sensor support, makes performing measurements with the SIRIUS DAQ systems easier than riding a bike. You will get it right the first time and the testing tasks will again become enjoyable.

Getting precise and graphically rich results is easier than ever. Just drag and drop one of the many ready-available visual displays and connect them to your physical or virtual math channels. Any changes you apply to customize your visual graphs are shown in real-time. It works like magic.

Very Intuitive and Easy to Use

DualCoreADC Technology

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 DAQ systems achieve more than 130 dB signal to noise ratio and more than 160 dB in dynamic range. This is 20-times better than 24-bit DAQ systems and 20-times less noise.

DualCoreADC Technology

Channel-to-Channel Galvanic Isolation

SIRIUS DAQ devices offer high galvanic channel-to-channel and channel-to-ground isolation (±1000 V). The DAQ systems even offer 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 the frequency bandwidth of the amplifiers. SIRIUS provides "worry-free" measurements, less noise, no ground loops, and the best possible signal quality.

For less demanding measurement and lower-cost applications, SIRIUS DAQs are also available in a differential version where only power supply isolation is offered.

Channel-to-Channel Galvanic Isolation

Precise Counter and Encoder Measurement

SIRIUS DAQ systems utilize a patented technology called SuperCounter®. The technology is available in every of its digital counter inputs.

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), 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 analog 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 SuperCounters​​​​​​​ inputs please navigate to Digital Counter PRO training course.

Precise Counter and Encoder Measurement

Analog Output

SIRIUS DAQ systems 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

Slide right to find more information about each use case.

Output Oversampling

Similar to the Sigma-Delta ADC 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.

Function Generator

With the SIRIUS analog output option, there is a need for additional analog out hardware.

The DewesoftX software offers a multi-channel function generator. Together with the SIRIUS analog out hardware options it can generate and output signals like sine, triangle, rectangle, saw, or even an arbitrary table. The generated signal can be continuous or in a sweep, step sweep, burst, and other modes. A lot of fine-tuning can be done in the function generator during the measurement in real-time.

Function generator on SIRIUS can be an excellent way to ex cite vibration shakers​​​​​​​ or any other device requiring simple analog input signals.

Standalone Signal Conditioning

With the analog out hardware option, the SIRIUS DAQ devices can be used as a pure, standalone signal conditioner.

No DewesoftX software or USB connection is needed. Any physical input signal is converted directly to an analog output voltage signal of max. ±10 V.

  • Any input possible
  • Signal conditioning: scaling, offset, gain
  • Redundant DAQ system: mathematic functions
  • Standalone operation possible

Control Channels

DewesoftX data acquisition software also features control channels that allow any SIRIUS DAQ device to directly access analog outputs and manually assign a value in real-time during the measurement. 

The control channels mode can be used for controlling peripheral hardware with actions like Start, Stop, Pause, Freeze, Store, Trigger, Screen event, Keyboard even, and many more. Choose out of many different instruments like vertical and horizontal slider bar, turning knob, buttons, edit box, etc...

File Replay to Analog

After the measurement is done and data recorded to the hard drive you can replay your data file and output the conditioned channels on the SIRIUS analog out channels.

This feature is useful for post-processing and analysis or to feed the data to a 3rd party testbed and simulate e.g. the vibrations during a test drive. 

For real-time data feed to a 3rd part EtherCAT master controller SIRIUS DAQ systems also offer Dual Mode capability. Dual-mode gives the ability to feed data to a 3rd party controller in real-time with very low latency. This is enabled through the SIRIUS EtherCAT devices via included EtherCAT port.

Analog Output

Data Synchronization

SIRIUS hardware is capable of reading different signals like the voltage, strain, ICP/IEPE, charge, CAN, counter, encoder, and digital. Additionally with the included DewesoftX 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 these 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 the sampled analog data.

Data Synchronization

Expand and Distribute

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

A rugged USB hub (DS-HUB7) is available for connection of up to 7 SIRIUS slices. 1 USB cable is then needed for connection from the USB hub to the PC or SBOX computer.

EtherCAT SIRIUS devices (SIRIUSe) are made to be easily distributed. Only one cable is required for data, power, and synchronization between each SIRIUS device. Cable length can span up to 100 meters between measurement nodes. With this, the DAQ devices can be placed close to the sensors. This increases the signal quality, reduces signal noise, and lowers the cost of the sensor cabling.

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

Fanless, Dustproof, and IP67 Waterproof Protection

SIRIUS modular DAQ systems are also available in a more rugged fanless chassis enclosure. SIRIUS fanless units are designed without any cooling fans and are much more suited for measurements in heavy industrial and dusty environments. 

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

IEPE Sensor Check

SIRIUS with ACC input amplifiers for Voltage and IEPE sensors have a LED ring around the connector. When an IEPE sensor is connected, SIRIUS will constantly check the current flow to the sensor and will turn the LED bright green or bright red, depending on if the sensor's impedance is okay.

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

IEPE Sensor Check
