What kind of sensors can I connect to SIRIUS data acquisition systems?

SIRIUS data acquisition system offers a full range of signal amplifiers available that can condition almost any signal. You can connect voltage, high-voltage, IEPE, charge, strain gauge based sensors (quarter-bridge, half-bridge, and full-bridge), load cells, thermocouple, RTD, LVDT, current. You can check the SIRIUS tech specs page for the full list of different amplifiers available.

What is DualCoreADC® technology?

The <a href="https://youtu.be/mzNyTn3W42s" target="_blank" rel="noopener">DualCoreADC® technology</a> 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 A/D converter. With SIRIUS data acquisition systems, each input 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 hardware achieves more than 130 dB signal-to-noise ratio and more than 160 dB in dynamic range. This is 20 times better than standard 24-bit data acquisition systems and 20 times less noise.

What sampling rates does SIRIUS DAQ systems offer?

SIRIUS data acquisition devices offer four different types of signal conditioners (or amplifiers) that offer different sampling rates: <ul> <li>SIRIUS DualCoreADC® amplifiers: 8 analog input channels per SIRIUS slice with a 200 kHz sampling rate per channel. Uses dual 24-bit Sigma-delta ADCs per input channel.</li> <li>SIRIUS HD (High Density) amplifiers: 16 analog input channels per SIRIUS slice with a 200 kHz sampling rate per channel. Uses a single 24-bit Sigma-delta ADC per input channel.</li> <li>SIRIUS HS (High Speed) amplifiers: 8 analog input channels per SIRIUS slice with a 1 MHz sampling rate per channel. Uses single 16-but SAR ADC per input channel. </li> <li>SIRIUS XHS (Extra High Speed) amplifiers: 8 analog input channels per SIRIUS slice with up to 15 MS/s sampling rate per channel. Uses our latest HybridADC® signal conditioning technology.</li> </ul> The sampling rate is software selectable globally for all input channels or separately for every individual input channel.

Are SIRIUS data acquisition system galvanically isolated?

Yes. SIRIUS DAQ devices feature a high galvanic channel-to-channel and channel-to-ground isolation (CAT II ±1000 V and CAT III ±600 V). SIRIUS amplifiers also offer isolated sensor excitation. You can learn more about in the <a href="https://www.youtube.com/watch?v=d71V0pjZbZ0" target="_blank" rel="noopener">SIRIUS galvanic isolation demonstration video</a>.

The top slice on the image shows an example of a customized front-end slice.

SIRIUS modular data acquisition (DAQ) system

Available signal amplifiers

SIRIUS® data acquisition systems offer different signal conditioning amplifiers grouped into three main amplifier families.

DualCoreADC® amplifiers

High dynamic range inputs (160dB)

These amplifiers feature dual 24-bit Delta-sigma ADC. Each channel amplifier has two A/D converters that measure the high and the low gain of the input signal in parallel. This results in the full possible measuring range of the sensor and prevents the signal from being clipped.

With DualCoreADC technology, SIRIUS data acquisition systems achieve more than 130 dB signal-to-noise ratio and more than 160 dB in dynamic range. This is 20x better than 24-bit DAQ systems and 20x less noise.

Each channel is capable of acquiring the input signal at a 200 kS/s sampling rate.

High-density (HD) amplifiers

SIRIUS high density amplifier (HD) schematic

Same Speed. More Channels. Optimized Price.

High-density (HD) amplifiers are built with the same dual 24-bit Delta-sigma ADC with an anti-aliasing filter and 200 kS/s sampling rate per channel. The main difference to DualCoreADC® amplifiers is that HD amplifiers use each of the two Delta-sigma ADCs as separate input and thus double the number of input channels while still keeping great signal-to-noise and dynamic range specs.

SIRIUS high-density signal conditioning cards thus offer double the input channels (16 analog channels) in the same chassis enclosure. These modules offer the best price-per-channel-to-performance ratio.

High-speed (HS) amplifiers

16-bit SAR ADC with high-speed sampling

SIRIUS® high-speed (HS) amplifiers are equipped with 16-bit SAR ADC. They offer high bandwidth and acquisition rates of up to 1 MS/s sample rate per channel. These amplifiers are suitable for recording fast transients and for applications where a high sampling rate is a must (such as power analysis).

The SIRIUS® modules with high-speed (HS) signal conditioning amplifiers are available in 8 analog input channel configurations.

IEPE Sensor Check

SIRIUS ACC and Charge signal amplifiers for IEPE sensors are equipped with a LED ring around the input connector for visual feedback that tells if the sensors are connected correctly. When an IEPE sensor is connected, the amplifier 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 such as accelerometers or microphones are working and are wired correctly. This is just another small but very useful detail that makes your life as a test engineer a little bit easier.

CAN and CAN FD interface

SIRIUS® signal conditioning slices are equipped with one CAN/CAN FD port for analyzing CAN bus data. Additionally, we provide a CAN-only SIRIUS® module that fits 9 CAN ports into one SIRIUS® module.

CAN interface supports transmitting and receiving CAN 2.0b data at a full speed of 1 Mbit/s. CAN FD interface supports high-speed CAN interface with data rates up to 8 Mbps. They are also compatible and allow decoding of J1939, J1587, and OBD II on CAN data as well.

All CAN channels are isolated for worry-free CAN acquisition in noisy environments and for maximum signal quality.

SIRIUS® CAN interface adds the possibility to:

Capture and synchronize CAN bus data with your analog inputs.
Advanced CAN recording, storing, and analysis.
Online monitoring and decoding of CAN messages.
Offline CAN message decoding.
Visual display for displaying CAN data.
Online and offline math analysis of CAN channels.

Lovedby Many Engineers

Dewesoft has transformed our approach to measurements. Prior to using Dewesoft, it would take us hours or even days to set up our measurement equipment. But now, everything can be done in a matter of minutes. With a clear data overview and multiple export formats, our work has become much more efficient. We greatly appreciate the almost instant support and assistance provided by Dewesoft. Any special requests or suggestions are addressed in a very short time. Truly, Dewesoft is the ultimate Swiss knife of the measurement world.

In our sport, where year-by-year data is the cornerstone of performance, having a partner like Dewesoft by our side is an irreplaceable source of success. Our focus is no longer on collecting data, but on finding the necessary resources of engineers to work on it!

I think I mentioned in previous emails how Dewesoft has mushroomed here, but even I didn't know how much. I was informed today that the data was being reviewed by up 50 to 60 different centers, along with NASA personnel as high as the manager of the entire Space Shuttle program.

It has been a long day, but before going home I wanted to say few things. Thank you from the bottom of my engineer heart and in the name of OneSubsea for what you did today! Yesterday at 10 PM I sent you an email asking for urgent help on a Saturday morning. 30 minutes later you replied you would come. This morning you were 5 people involved in resolving the issue. I have never experienced such customer service! Thanks again, customer service matters a lot to us, and today's response blew me away.
