Highlights

USB/EtherCAT Interface

SIRIUS modular data acquisition systems can be connected via USB or EtherCAT® interface to any Windows-compatible PC or to one of our high-performance SBOX processing computers and data loggers running our award-winning DewesoftX software.

Connect Any Sensor

Array of different amplifiers are available that can acquire data from virtually any sensor on the market. IEPE, voltage, high voltage, charge, full/half/quarter bridge, LVDT, RTD, thermocouples, current, resistance, counter, encoder, and digital inputs are available.

Universal Analog Inputs

Truly universal analog inputs are available that can accept voltage, IEPE, full/half/quarter bridge, RTD, and resistance signals natively. Additional input modes such as charge, thermocouple, RTD, current, and LVDT signals are supported via our DSI adapters.

160 dB Dynamic Range

Our DualCoreADC® technology boosts dual 24-bit delta-sigma ADC's with an anti-aliasing filter on each analog channel, achieving an astonishing 160 dB dynamic range in time and frequency domain with 200 kHz sampling rate per channel.

High Sampling Rate

SIRIUS signal amplifiers offer high acquisition speeds of up to 1 MS/s per channel. The sample rate is software-selectable per every input channel.

High Galvanic Isolation

SIRIUS signal conditioners provide high ±1000 V channel-to-channel and channel-to-ground galvanic isolation. This prevents damage to the systems from excessive voltage and avoids ground loops.

Flexible and Scalable

SIRIUS DAQ system can grow with your needs. You can start with a single channel and scale the system to thousands of channels at any time.

Fully Synchronized

All input channels - analog, digital, and CAN - are fully synchronized with each other with microsecond accuracy. Multiple devices can be further daisy-chained and synchronized with the same pin-point synchronization accuracy.

Sensor Power Supply

Amplifiers provide channel-independent, programmable power supply for sensor excitation.

SuperCounter® Inputs

Each counter channel input is capable of three digital inputs, one event counter, encoder, period, pulse-width, duty-cycle, and precise frequency and angle measurement using patented SuperCounter® technology.

CAN and CAN FD Input

SIRIUS modular devices offer one high-speed CAN 2.0b and CAN FD interface with 1 Mbit/sec data throughput with additional support for XCP, CCP, OBDII, J1939, and CAN output.

Analog Outputs With Function Generator

SIRIUS slice can be configured with 8 analog outputs which can also function as a multi-channel function generator (software option upgrade required), analog replay, or control device with the output voltage signal of ±10V.

Software included

Every Dewesoft data acquisition system is bundled with award-winning DewesoftX data acquisition software. The software is easy to use but very rich and deep in functionality. All software updates are free forever with no hidden licensing or yearly maintenance fees.

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.

Intuitive and easy to use

Using Dewesoft data acquisition systems does not require any complex configuration setups or programming knowledge. We also kept this in mind when designing SIRIUS® XHS.

Plug-and-play technology with smart sensors and advanced TEDS is supported by default. This makes performing measurements with the Dewesoft DAQ systems easier than riding a bike. You will be ready to measure in no time.

Getting precise and graphically rich results is easier than ever. The drag-and-drop user interface of bundled DewesoftX software will allow you to define your measurement screens and results in no time. A rich mathematics library for signal processing is also available one click away. Just connect the right widget with your input channel and Voila! Works like magic.

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.

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.

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 synchronizedwith analog, CAN bus, and other data sources to enable easy applications like balancing, order tracking, and torsional vibrations.

Input Amplifiers for Every Sensor

SIRIUS offers a range of different signal amplifiers for almost every signal type and connection of practically any type of sensor. SIRIUS slices are available in two versions:

• Galvanically isolated version with 1000V galvanic channel-to-channel and channel-to-ground isolation.
• Differential version with differential inputs and isolated power supply.

Standard or Customized Front-End Configuration

SIRIUS slices are available with 8 or 16 channels per slice. Standard front-end configurations are available or you can freely customize each of the eight available channel slots from the list of available amplifiers. With some amplifiers, you can choose several connector types. At your request, we can develop a custom connector type. Please contact us to discuss that option.
