High-speed data acquisition and transient recorder

The new imc EOS stands for speed! With sampling rates of up to 4 MHz, imc EOS allows precise analysis of very fast dynamic processes. Voltage, current transducers and IEPE sensors can be connected at four isolated inputs to measure acceleration, sound or force.  The areas of application are diverse: from high-speed recorder use in blasting tests to structure-borne noise and vibration measurements, analysis of switching processes on control units or airbag and crash tests, right through to e-mobility applications. An especially attractive feature is the possibility to operate imc EOS synchronously together with other imc measurement systems.

Fast and flexible measurement amplifier

imc EOS offers high-end measurement technology in a compact device. Four galvanically isolated precision amplifiers ensure perfect signal quality even in demanding electromagnetic environments. Each signal input is via either a BNC or LEMO connection that can be chosen according to sensor technology. Voltage signals up to ±100 V, IEPE/ICP sensors such as accelerometers, microphones or piezoelectric force sensors can be measured. Precision current transducers are also supported. The acquired signals are digitized with 24 bits at up to 4 MHz per channel – the analog bandwidth extends to 1.8 MHz. An optional individually configurable sensor supply of 2 Watts per channel for feeding active sensors leaves nothing to be desired.

 

Safe Storage

imc EOS can be equipped with an integrated flash memory of up to 1 Terabyte. This makes imc EOS an autarkic high-speed recorder suitable for use entirely without a PC. The system can also be comfortably configured, started and stopped remotely from a distance via WLAN. Onboard industrial-grade solid state storage ensures the safe internal storage of measurement data independently of a fast network connection. Furthermore, a flexible trigger machine  allows the data to be accurately reduced to relevant events. Additionally, data can be streamed via the Gigabit Ethernet interface to a PC for visualization and permanent archiving.

Integrated Comprehensive Solution

The demands placed on modern test environments are constantly increasing. In addition to the acquisition of classic mechanical and physical quantities such as strain, pressure, temperature and voltage, along with the variables of process control, field buses and others, there is also an increasing need for acquiring very fast signals in high resolution. Examples of this include ECU control signals, high dynamic range sensors and actuators or electromagnetic subsystems. Oscilloscopes, the classic solution frequently used in the past, usually fail to meet these high demands. The demand is for very precise, high resolution digitization far in excess of 12 bits, integrated sensor conditioning and seamless integration into one comprehensive system capable of acquiring, displaying, correlating and analysing all relevant quantities together. This calls for new approaches to measurement that synchronously bring together “slow” and “fast” data acquisition. With imc EOS this is child’s play, because it works together synchronously with all imc measurement data acquisition systems.

Furthermore, it is completely compatible mechanically with the imc CRONOSflex product family. imc CRONOSflex base units, as well as measurement modules and accessories, can be clicked together directly. This creates a comprehensive, integrated complete system for demanding test tasks that need only one power source. All connected devices are automatically supplied via an integrated backbone.  

Wide range of accessories

The versatile range of accessories in the imc CRONOSflex series, such as power supply modules or handles, battery-buffered UPS solutions (“power handle”) or sensor supply modules for high-performance current transducers and current clamps, are compatible with imc EOS measurement devices.

Furthermore, with imc NET-SWITCH – also with a click connection – a 5 port GBit network switch is available to the user, enabling the synchronous networking of systems. An especially comfortable feature: complete systems clicked together only need to be powered

Comfortable measurement technology software

As with all imc measurement systems, imc EOS operates with the uniform measurement software imc STUDIO. This software offers full control over the complete measurement process: from channel configuration through to the report. imc STUDIO brings together data acquisition, visualization, analysis and test automation. Regardless of whether you configure your imc EOS for fast mobile measurement in “black box” testing or for comprehensive testing with several imc systems and hundreds of channels, including synchronous video capture – with imc STUDIO you have full control over your complete measurement process.
