The EP3751-0260 EtherCAT Box module features an internal ultra-low-noise 3-axis accelerometer with 20-bit resolution and a selectable measuring range of ±2 g, ±4 g, and ±8 g. The sampling frequency is 4 kHz. The built-in sensor is suitable for applications where low frequencies must be monitored with the lowest possible noise. Possible applications include building monitoring, bridge monitoring, robotics, and condition monitoring.
The box also features a 3-axis MEMS gyroscope sensor to record rotational movements across the three axes. The integrated sensor operates quietly and remains stable regardless of temperature.
The integration of EtherCAT ensures virtually delay-free transmission and subsequent evaluation in the measuring system – for example, with TwinCAT Analytics. The sensor data can also be transmitted as raw values (unprocessed/filtered) – for example, to be filtered, processed, and evaluated using TwinCAT Analytics.
