SoMat eDAQ
The SoMat eDAQ system has set the standard for Rugged, Mobile Data Acquisition.
The SoMat eDAQ is a sealed stand-alone data acquisition system for testing in the harshest of environments. It has leading-edge signal conditioning and a capacity to perform a broad range of on-board data processing. Engineered to be rugged and mobile, the eDAQ is swept sine tested to 20g’s. Input power for the system operates in a wide range from 10-60 VDC, and internal back-up batteries protect the eDAQ from unplanned power losses or low voltage events. Hundreds of synchronous channels are possible in a single system, with virtually limitless channel counts when networking these Ethernet-based systems.
Overview
Rugged
This is a subjective term. For SoMat eDAQ customers; it can be “the eDAQ fell of the truck and we dragged it by its cables”, or “we dumped that motorcycle and were still able to upload the data”. This of course is all in a days work for a system that is swept sine tested to 20 g’s. The eDAQ is also a sealed system; there are no cooling fans, filters, open cards or drives. eDAQ customers can just laugh about the day “that hydraulic hose ruptured spraying oil over everything”, or “we were summer testing in Death Valley and the wind was blowing sand everywhere.” Product testing is expensive; being rugged isn’t just limited to the application, rugged equals' reliability. It means, “We used another data acquisition system and when I arrived in Japan it broke on the flight over.” Or, “the other system we have spends more time in repairs then collecting data”. The eDAQ isn’t built from commercial components; it doesn’t run Windows. It is constructed of proprietary designed layers and specified components for the sole purpose of rugged mobile data acquisition. The eDAQ has a custom Linux OS and an indestructible file format. The “blue screen and my data is lost” doesn’t happen on an eDAQ system.
Mobile
Few data acquisition systems are truly designed from the ground up to work on mobile equipment. The mobility of an eDAQ isn’t an afterthought; a laboratory system in a rugged case with a new suffix in the part number like other “mobile systems”. It is specifically engineered for these applications; input power for the system operates in a wide range from 10-60 VDC. Internal back-up batteries protect the eDAQ from unplanned power losses or low voltage events. The eDAQ uses Ethernet communications, and hosts its own web server with a configurable IP. This combination allows the eDAQ to effortlessly communicate through wireless WWAN modems. You can have access to it anywhere in the world.
Data Acquisition
Any data logger can collect a time history; but the eDAQ isn’t a logger, it is a data acquisition system with leading edge signal conditioning and a capacity to perform a broad range of on-board data processing. This includes; custom computed channels, triggers, gates, boolean expressions, and the SoMat DataModes™. Utilizing the SoMat DataModes™ allows users to save data in multiple, easy to manage and analyze formats including; Burst History, Time-at-Level, Event Slice, Peak/Valley and Rainflow Histograms. Just as the eDAQ pioneered physical data acquisition and the correlation of vehicle bus parameters and GPS. Continued development and further enhancements will ensure you’ll be able to use the system for many years to come.
