Structural Health Monitoring Systems

The IOLITE 3XMEMS-ACC is a data acquisition system for structural health monitoring systems.

It is ideal for permanent condition monitoring on structures such as bridges, buildings, and stadiums.

The Dewesoft IOLITE 3XMEMS-ACC are structural Health Monitoring Systems with an integrated sensing device.  Firstly, a triaxial MEMS accelerometer is inside the device.  It is attached to a mechanical chassis that measures acceleration.  Analog to digital conversion is done inside the device.  Therefore, eliminating any noise that is picked up in analog cabling.

Secondly, the microprocessor inside the unit transmits the acceleration samples over into DewesoftX software running on a Windows PC.  Or alternatively to any controller running EtherCAT master on any platform.  Scaling is automatic.  Therefore, any data in g or m/s2 is available for the user immediately.

Thirdly, an internal temperature sensor measures the temperature of the MEMS accelerometer.  Finally, this information is display inside the DewesoftX Data Acquisition Software as a System Monitor Channel.  Values updated once per second.

Main Features of the Structural Health Monitoring Systems include:

ALL-IN-ONE: IOLITE 3xMEMS-ACC is a data acquisition device with an embedded triaxial MEMS accelerometer, analog-to-digital conversion, and EtherCAT interface based on the IOLITE4 DAQ device platform.

LOW NOISE DENSITY: The device has a very low noise performance of 25 μg√Hz noise density. Making it a cost effective solution for seismic measurements

ALSO DISTRIBUTABLE & SYNCHRONISES MULTIPLE DEVICES: Easily distribute and synchronise multiple devices over large structures using one cable that can span up to 50m node-to-node.

GREAT PRICE VS. PERFORMANCE: The device offers a good price vs. performance ratio and is thus perfect for system integrators, and large continuous monitoring installations.

VERSATILE MEASUREMENT: The device can measure acceleration in the X, Y, and Z axes. Software calculations in Dewesoft X allow you to calculate velocity and displacements as well as static pitch and roll angles from the DC acceleration values.

WATERPROOF ENCLOSURE: Waterproof enclosure is optionally available. With waterproof aluminium casing with cable glands. The enclosure is for permanent outdoor condition monitoring.

SOFTWARE INCLUDED WITH FREE LIFETIME UPGRADES: The easy-to-use but rich in functionality, award-winning DewesoftX data acquisition software is included. All software upgrades are free forever with no hidden licensing or maintenance costs.
