SIRIUS® signal conditioning technology

Data acquisition systems are built around our world-class SIRIUS® signal conditioning technology and offer the same top-performing technologies:

DualCoreADC® technology: high-dynamic range and signal-to-noise ratio (SNR).
SuperCounter® technology: high-speed synchronized angle and speed measurement.
Galvanic isolation: channel-to-channel and channel-to-ground isolation for best signal quality and safety.

Note: galvanic isolation does not apply to SIRIUS mini and MINITAURs instruments.

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.

DualCoreADC® signal conditioning technology

The DualCoreADC® technology solves often-faced problems with signal measurement:

signal input overload,
noise, and
artificial frequencies in the signal caused by aliasing.

The input signal can be higher than expected by the signal conditioner (out-of-range) and therefore clipped by the ADC. This will result in an incorrect measurement and will require you to repeat the test all over again.

DualCoreADC technology prevents these problems. 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.

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.

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.

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

Integrated GNSS positioning with RTK correction

SBOX computers can optionally be equipped with a 10 Hz or 100 Hz GNSS receiver for precise position measurement applications. GNSS receivers can optionally also be configured to support RTK correction (Real-Time Kinematics).

GNSS receiver option will transform your data acquisition system and makes it ideal for precise position-based test and measurement applications. The RTK correction option will improve the positioning accuracy down to 1 cm.

SBOX with GNSS receiver will transform the data acquisition system into a powerful automotive data logger for advanced position-based test and measurement applications such as:

Brake testing
ADAS testing
Pass-by-noise
Vehicle dynamics
Road load data
and others.
