SoMat DataModes™ - Intelligent data storage

Any data logger can collect time series data, but the SoMat eDAQ can do far more! It is a stand-alone data acquisition system with a capacity to perform a broad range of on-board data processing. This real-time data processing is achieved utilizing SoMat DataModes™ technology.

Developed with over 25 years of mobile data acquisition expertise, DataModes™ allow you to save data in multiple, easy-to-manage formats for analysis.

DataModes™ preserve memory, provide instant analysis to the data, easily manage long-term tests, and the wireless design allows effortless transfer. Various triggering options make sure you not only get your data in the format you want, but also when you want it.

Input

Physical: Analog, strain gage, thermocouple
Computed: Mathematical expression
Vehicle bus: CAN, J1850 VPW, ISO 9141, J1708
GPS: Position, speed, time
Time: System time

Trigger Mode

Trigger: Start recording data after the first trigger condition is true
Gate: Record data only when the trigger condition is true
One shot: Record one data point when trigger goes from false to true
Always on: Record all data from start to stop of a test

SoMat Data Modes

Time history: Sequential storage of all data values
Time burst history: Sequential lone transient recordings based on pre- and post-triggers times
Sequential peak-valley: Sequential storage of signal reversal points removing insignificant data
Peak-valley matrix: Histogram categorizes load histories to successive peak-valley transitions
Rainflow histogram: Histogram categories load histories according to fatigue damage
Time at level (single dimension): Histogram records discrete values
(bins) of single channel over time
Time at level (multi-dimension): Histogram records statistical correlation with up to 7 inputs
Event slice: Sequential storage of all channels based on master channel(s) trigger

Last Time Buy

Please note: Due to the huge success of our eDAQ product series in the last months, we have decided to extend the lifetime of the main components until further notice. This extended selling period allows you to fulfil your requirements for the next few years and continue testing with your equipment. Click here for more details.

Furthermore, we will continue to support you as we have done in the past years.

Calibration and technical support are offered at least until December 2030
Repair services and accessories will be offered based on availability of parts but at least until December 2025 – and possibly even 5 years longer

If you are not an existing eDAQ user, we recommend that you check out SomatXR, our new modular ruggedized DAQ series.

SoMat Vehicle Bus Modules

The SoMat Vehicle Bus Modules condition vehicle network parameters to be synchronously measured by SoMat eDAQ and SoMat eDAQlite systems. Supported parameters include:

CAN (J1939)
SWC (Single Wire CAN)
J1708 (J1587)
J1850-VPW
ISO-9141(kWP-2000)

This offers a direct correlation between vehicle bus channels with physical data (including analog, thermocouple, frequency) as well as GPS. Up to 254 channels
can be recorded per module.

Wireless synchronization via GPS

SoMat eDAQ and SoMat eDAQlite systems can be integrated with GPS receivers. A unique feature of SoMat eDAQ is its ability to synchronize using the GPS timing signal. You can configure the SoMat eDAQ to generate the Master Sample Rate clock in synchronization with GPS time.

This mode of operation allows multiple SoMat eDAQs to be wirelessly synchronized. For example, a SoMat eDAQlite on a moving truck can be synchronously collecting data with the SoMat eDAQ on a fixed bridge, or a high-speed train can be synchronously measured together with a rail-mounted system.
