Performance

The ASC DiSens® MD is part of ASC’s innovative DiSens® series with digital interfaces, combining high-quality accelerometers with integrated data acquisition. This eliminates the need for separate DAQ systems, reducing cost and complexity. Thanks to digital transmission, interference is minimized, making the MD model especially suitable for applications with long cable runs.

The ASC DiSens® MD is a triaxial digital accelerometer with software-selectable ranges of ±2 g, ±4 g and ±8 g. Acceleration values are transmitted as raw digital data via EtherCAT protocol to a host system, where they are processed by analysis software. Up to 12 devices can be daisy-chained with an active power supply .

Usage conditions

Housed in a lightweight aluminium enclosure, the sensor is rated IP20 and designed for protected installations. It operates reliably from −20 °C to +60 °C with a supply voltage of 12–48 VDC. Daisy chaining with shielded CAT5e/CAT6 cables allows multiple devices to be connected in sequence, with up to 50 m distance node-to-node.

Applications

Structural health monitoring of bridges and buildings
Seismic measurement and earthquake research
Vibration monitoring on construction machinery
Condition monitoring on industrial equipment
Monitoring of mobile network antenna structures

Advantages of choosing this product

The ASC DiSens® MD combines high resolution, digital output, and robust MEMS technology with EtherCAT connectivity. Its integrated DAQ functionality reduces system complexity, while daisy chaining enables scalable installations. Delivered with DEWESoft X3 software, it provides a complete solution for recording, analysis and reporting.
