Main Features

  • USB POWERED ON THE GO: SIRIUS mini does not require any external power supply. It can be powered straight from the USB connection, for example, a laptop. Two USB cables are included. One for power, second for data transfer.
  • SMALL FORM FACTOR: SIRIUS mini is our smallest 4-channel data acquisition system. It fits into one hand, is light, and is easily transported in a backpack. Still, in this small box, you can find the power of a giant. 
  • 4 IEPE AND VOLTAGE INPUTS: Data acquisition system is configured with four high dynamic analog inputs for direct voltage or IEPE/ICP signals. Amplifiers are equipped with two 24-bit Sigma-Delta ADC's with a 200 kHz sampling rate per channel. DualCoreADC® technology offers an astonishing 160 dB dynamic range. 
  • COUNTER/ENCODER/DIGITAL INPUTS: SIRIUS mini can also be configured with one counter/encoder input. Input is capable of 3x digital inputs, 1x event counter, encoder, period, pulse-width, duty-cycle. Precise frequency and angle measurement use our patented SuperCounter® technology. 
  • UNMATCHED PRICE: SIRIUS mini offers a very attractive ratio between price and quality. It ships with the highest quality signal conditioning amplifiers and is bundled with award-winning data acquisition software. 
  • SOFTWARE INCLUDED WITH FREE LIFETIME UPGRADES: Our award-winning data acquisition software DewesoftX is included for no additional cost. The software also comes with lifetime free updates and free technical support. No hidden costs!
  • DEWESOFT QUALITY AND 7-YEAR WARRANTY: Enjoy Dewesoft’s industry-leading 7-year warranty and world-class quality assurance. Your investment into the Dewesoft equipment is always paid-off and protected.

Compact and Portable Noise and Vibration Analyzer

SIRIUS mini is a very compact and portable data acquisition system that can be USB powered directly from your laptop. It is perfect for acoustic noise measurement as well as vibration measurement and vibration analysis on all sorts of rotating machinery.

Four direct voltage and IEPE/ICP® analog inputs allow acquiring data from four IEPE accelerometers, microphones, or voltage sensors at the same time. Additional counter/encoder/digital input adds the ability to connect any counter/encoder sensor and measure RPM, angle, and frequency on rotating parts.

SIRIUS mini can easily also be used as a portable vibration analyzer for preventive maintenance or similar task.

SIRIUS Technology
For the Highest Signal Conditioning Quality

SIRIUS mini is built with the same data acquisition technology as our flagship SIRIUS DAQ systems. SIRIS mini offers the same powerful technologies:

  • DualCoreADC® technology - amplifiers with DualCoreADC® technology include dual 24-bit ADC's with 200 kS/s/ch sampling rate and achieve an astonishing 160 dB dynamic range in time and frequency domain. This is ideal for dynamic measurement and analysis. See the video.
  • SuperCounter® technology - this technology provides precise and synchronized analog angle and frequency measurement from digital counters. This serves as the basis for order tracking analysis, torsional vibration, and similar applications. See the video.

Please note that all amplifiers on SIRIUS mini are differential due to the USB power source.

160 dB Dynamic Range
DualCoreADC Amplifier 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.

160 dB Dynamic RangeDualCoreADC Amplifier Technology

Precise Counter and Encoder Measurement

SIRIUS MINI data acquisition system utilizes a patented technology called SuperCounter® on its single digital counter input.

Counter input 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 input is fully synchronized with analog inputs and other data sources from other instruments. Counter input is perfect for measurement applications like balancing, order tracking, and torsional vibrations.

For more information on our SuperCounters inputs please navigate to the Digital Counter PRO training course.

IEPE Sensor Check
Be Always Sure Your Sensors Are Working

SIRIUS MINI instrument has a convenient LED ring around the input BNC connector. When an IEPE sensor (e.g. accelerometer or microphone) is connected, the device 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 the 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 CheckBe Always Sure Your Sensors Are Working

USB Powered
From Any USB Source

SIRIUS mini does not require any external power supplies or adapters. Simply plug it into your PC laptop computer via the included USB cable, and it will receive enough power for full functionality. Once connected you are ready to start measuring.

USB can provide enough power to power the device itself and also provide excitation to connected IEPE sensors like accelerometers and microphones.

SIRIUS mini package includes two USB cables. One cable is used for data transfer while the other is for powering the device.

Maximum Portability
Take It Anywhere

SIRIUS mini is so small and light that you can easily fit it into a laptop bag or backpack:

  • Weight: 0,75 kg (1.6 pounds)
  • Dimension: 146 x 139 x 64 mm (5.75 x 5.47 x 2.52 inch).

But it is not only small and light. SIRIUS mini is also built to last. It features aluminum chassis which is CNC milled out of a single aluminum block.

The chassis and electronics were thoughtfully tested inside our state-of-the-art testing labs. SIRIUS mini has been tested for vibration on the shaker table and impact test machine so that you will be able to work without worries, no matter the environment you are testing in.
