Data Acquisition and Real-Time Control Merged in One System

SIRIUS RT systems (R2rt, R4rt, and R8rt) offer our world-class data acquisition combined with a real-time low-latency EtherCAT bus. They incorporate the same SIRIUS data acquisition technologies, high-end signal conditioning, built-in SSD data logging, and a very powerful signal processing computer.

EtherCAT slave port allows the system to be connected to any 3rd party EtherCAT master or real-time controller. This allows the system to feed the acquired data in real-time.

SIRIUS RT systems bring the worlds of data acquisition and control into a single, simple to use instrument, allowing them to perform two tasks simultaneously:

  1. Acquire, store, and process signals from virtually any sensor with high-end signal conditioning amplifiers to an internal computer with a solid-state drive.
  2. Send the acquired data in real-time through the real-time EtherCAT port to any 3rd party EtherCAT master.

Integrate Into Existing Test Bench Real-Time Controllers

Traditionally you need to purchase and configure additional control system I/O's to bring data from analog sensors and data acquisition systems to the test bench controllers. With SIRIUS RT systems this is done faster, cheaper, and also much more accurate.

SIRIUS RT system can feed the data to the test bench controller in real-time via only one cable over the EtherCAT protocol. This completely removes the need for traditional control system I/O's, clumsy analog cabling, and complex configurations.

SIRIUS RT solution is unique on the market. It brings many improvements to your test routines. Scroll down to see why this solution will save you time and money.

Integrate Into Existing Test Bench Real-Time Controllers

1. Save Money
One System for Multiple Tasks

SIRIUS RT systems will save you money on several stages of your testing process. The Dewesoft DualMode functionality will allow you to use the same system for highly accurate data acquisition as well as a signal conditioning device for your real-time test bench.

Thanks to the EtherCAT real-time interface, no analog input stage is needed on a 3rd party controller. This means no additional analog I/O hardware and much much fewer cables which saves you costs.

1. Save MoneyOne System for Multiple Tasks

2. Save Time
Simplified Configuration

R8rt DAQ system removes the clumsy and time-consuming configuration of additional analog I/O's required by the test bench controllers. Only one ethernet cable is needed between the R8rt instrument and the real-time controller.

The included Dewesoft X data acquisition software can send the channel EtherCAT configuration to the controller with a single click. This is not just fast and easy but also greatly reduces human errors.

The image on the right shows the amount of the I/O cables removed with the R8rt solution at one of our automotive customers.

2. Save TimeSimplified Configuration

3. Better Signal Quality
Remove Clumsy Analog Cables

As previously mentioned, the SIRUS RT systems offer high-end signal conditioning amplifiers based on world-class SIRIUS data acquisition technology.

In practice, this means that perfectly conditioned signals are transmitted to the test bench controller digitally via a single EtherCAT cable instead of sending each individual channel via analog cable, which requires hundreds of meters of analog cables.

This greatly removes the chance of catching any noise and other unwanted frequencies and also greatly reduces the chance of wiring errors. 

3. Better Signal QualityRemove Clumsy Analog Cables

Cutting-Edge Data Acquisition Technology

SIRIUS RT data acquisition systems are built around SIRIUS data acquisition technology. Technologies like high-isolation, DualCoreADC®, SuperCounters®, smart sensors bring worry-free measurements and the best signal quality.

The SIRIUS RT systems can be equipped with any of the available SIRIUS signal amplifiers:

  • DualCore Amplifiers: High-dynamic analog inputs featuring DualCoreADC technology. Dual 24-bit delta-sigma ADC with a 160 dB dynamic range and acquisition speeds of 200 kHz per channel.
  • High-Density Amplifiers: 24-bit delta-sigma ADC with acquisition speeds of 200 kHz per channel. High-density amplifiers provide double the input channels.
  • High-Speed Amplifiers: 16-bit SAR ADC with acquisition speeds up to 1 MHz per channel.

Learn more about Dewesoft data acquisition technology.

Cutting-Edge Data Acquisition Technology

Signal Conditioning 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.

DualCoreADCSignal Conditioning Technology

Galvanic Isolation
High Channel 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.

Galvanic IsolationHigh Channel Isolation

Precise Counter and Encoder Measurement

SIRIUS RT 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.
