Dewesoft offers wired and wireless data acquisition devices (DAQ) depending on the application and sensor requirements. Wired and wireless DAQ's can be easily combined in the same system providing the most reliable, easy to install, and at the same time cost-effective solution on the market.
Structural Health Monitoring Systems
- DISTRIBUTABLE AND SCALABLE: A wide variety of wired or wireless amplifiers with different channel counts per module allows perfect channel distribution for monitoring.
- HIGH-END SIGNAL CONDITIONING: Dewesoft offers high-quality analog amplifiers with excellent signal conditioning and up to 50 kHz sampling rate.
- ANY SENSOR: Input amplifiers offer support for any velocity, accelerometer, temperature, vibrating wire strain gauge, piezometer, inclinometer, weather station, and almost any other type of sensor needed in geostructural monitoring.
- IP20 to IP67 degree of protection: Our amplifiers are designed to work in any condition and are thus suitable for indoor applications as well as for field monitoring in extreme and harsh environments.
- PLUG-AND-PLAY: Dewesoft data acquisition devices offer plug-and-play functionality with TEDS support for automatic and easy setup of sensors.
Wired Data Acquisition devices
We offer a fleet of EtherCAT-based data acquisition devices able to read data from almost any kind of dynamic sensor used in geostructural monitoring applications.
- All-in-one devices including sensor and data acquisition devices.
- Single-channel or multiple channel amplifiers to connect different sensors.
Pros and cons of Wired solutions:
In applications where dynamic (almost real-time) measurements are required and synchronization between devices really matters. Wired data loggers are based on the industrial EtherCAT communication protocol. Devices can be daisy-chained with a single inexpensive CAT6 cable providing power, data, and synchronization (down to 1 ms) up to 100m device to device.
A cable to connect the devices is needed.
All-in-One DAQ Devices
Cost-effective solutions for dynamic measurements with embedded MEMS sensors and data acquisition devices in a single box.
IOLITEi 3xMEMS device is a DAQ device with an integrated low-noise MEMS accelerometer. There are four versions available:
- 3xMEMS-ACC-8g: 25 ug/sqrt(Hz) noise density, selectable measurement ranges: 2 g, 4 g, 8 g
- 3xMEMS-ACC-40g: 75 ug/sqrt(Hz) noise density, selectable measurement ranges: 10 g, 20 g, 40 g
- 3xMEMS-ACC-INC: temperature-compensated offset drift to allow more accurate static inclination measurement
- 3xMEMS-ACC-S: lower noise edition with less than 1 ug/sqrt(Hz) noise density at 15 g measurement range
All versions are available in IP20 (IOLITEi) or IP67 (IOLITEiw) waterproof/dustproof casing.

Single or Multiple-Channel DAQ Devices
A perfect solution where remote dynamic measurements of a small or large channel count are needed on a single spot. Available in IP20 version and IP67 casing.
Available sensor interfaces to connect:
- dynamic strain gauge
- static strain (optical)
- low noise/seismic accelerometers
- temperature (RTD or TC)
- voltage +-10 V
- current 4..20 mA
Wireless Data Acquisition Devices
A perfect solution for remote static measurements of a small or large channel count. Available in IP67 version.
Available sensor interfaces to connect:
- vibrating wire sensors (VW Strain gauges, potentiometers, crack meters, joint meters, extensometers, load cells)
- MEMS tilt sensors
- digitally bussed sensors
- 4-20mA sensors
Pros and cons of Wireless solutions:
Cost-effective, easy to install, and capable of interfacing with Vibrating Wire sensors (including piezometers, crack meters, and strain gauges) and thermistors. Ideal for remote location monitoring.
Not appropriate for dynamic measurements (accelerometers, tiltmeters) and where precise synchronization between devices is necessary because of communication protocol and battery life limitations.
Geostructural Monitoring System Architecture
Depending on the application and monitoring purpose, different sensors are used for Structural Health Monitoring. Sensors are installed on the structure providing static or dynamic data about structure behavior.
Dynamic sensors are connected to the EtherCAT-based Data acquisition devices. Multiple EtherCAT devices can be connected to the same network giving the possibility to build a virtually unlimited channel chain by using a single cable delivering power, synchronization, and data. The whole EtherCAT chain is synchronized to 1us independent of the cable length. Node-node distances can be up to 100m.
Wireless DAQ devices are used to connect static sensors.
Data from wireless and Wired DAQ devices are collected and processed by Measurement Units (Computer) running the DewesoftX software. Processed data is sent over the TCP/IP network to the factory or cloud server. Data can be accessed and viewed on the client PC or stored in the time series database (Historian) and served to SCADA systems or Cloud Software using standard interfaces such as OPC/UA or XCP to truly support Industry 4.0 applications.
