For various testing tasks such as powertrain efficiency, NVH testing, temperature testing, energy flow testing, throttle characteristics, thermal balance and brake testing, the DEWETRON multi-channel data acquisition system provides an integrated solution. Some tests can only be performed under real driving conditions, while others can only be performed on a test bench: the system provides DC-powered and battery-powered instruments for on-vehicle testing under real driving conditions, and all systems can also be used for bench testing. The user-replaceable TRION3 modules allow users to configure a system with from a few to over a hundred channels according to their needs.

The TRION3 series signal conditioning modules measure analog signals from various types of sensors with strict synchronization; each channel has an independent AD converter and an anti-aliasing filter; the modules can be replaced simply at any time and are automatically recognized by the software once installed. For example, dozens of additional temperature test channels (Pt100, thermocouple) can be added to a power analyzer, and acceleration, sound, speed, bridge and strain measurement channels, CAN, GPS, inertial and navigation systems and video signals can be further expanded — all of this can be realized on a single device.

The included OXYGEN test software provides complete functions for testing tasks: real-time efficiency maps, order analysis, bird's-eye view, sound level meter, FFT and octave analysis can be used during or after data recording; data can be exported in multiple formats, and report generation and multi-channel video acquisition are supported. With the DEWETRON system, multiple testing tasks can be performed with a single system.

Product Features
