Fast and synchronous measurements
Type STG6 pro BS20 | STG6 BK20
EtherCAT®-based measurement modules for decentralized use under demanding conditions: Robust, very compact and with six time-synchronous strain gauge inputs for quarter, half and full bridges.
The strain gauge measurement modules of the STG6 ECAT series allow multi-channel strain gauge measurements under demanding conditions. Thanks to their compact and robust housing, they can be used in a decentralized manner. Up to 100 measurement modules can be cascaded electrically and mechanically, allowing even large objects to be tested easily and with many measurement points.
The extended range of the excitation from 1 to 10 V makes the STG6 pro BS20 suitable for many applications. In addition, with the automatic selection of the input voltage range and the very good signal-to-noise ratio, extremely small measurement signals can be accurately acquired.
