Road Load Data Logger and Signal Conditioning for MTS Test Bench

Data Acquisition and Control in parallel Manufacturers in the automotive and aerospace industry typically use different data acquisition instrumentation for in-vehicle and test bench testing. However, thanks to combining two data buses (USB and EtherCAT®) and MTS implementing the EtherCAT® communication on the FlexTest® series controllers, the Dewesoft data acquisition systems offer an ideal solution for both scenarios. The same Dewesoft R8rt data acquisition system can be used as: A high-channel-count test bench data acquisition system Real-time signal processing for road load analysis feedback (over EtherCAT) It can also function as a compact size high-performance mobile data logger for in-vehicle data acquisition use. The new FlexTest digital controller software features support for EtherCAT communication. This offers a more cost-effective, ethernet-based digital link to third party sources of data. The added EtherCAT support enables FlexTest users to establish digital communication with data acquisition systems. SIRIUS DAQ systems have already been used in many signal conditioning applications for test bench instrumentation. But only as a preamplifier with analog output of +-10 V which was used as an input to the controller analog input stage. The secondary input stage can now be completely removed thanks to the direct conversion of analog data to the EtherCAT bus inside the SIRIUS data acquisition systems. This significantly improves the user experience since there is no need for the additional controller analog inputs.
