Wireless Tiltmeter – Structural Health Monitoring

By Cody Corporation

Wireless Tiltmeter

The Move Wireless Tiltmeter measures the angle of inclination of the point where it is installed with an incredible accuracy and resolutions. The device transmits the measured angle at regular time intervals. It is full wireless, and battery can lasts for eight years. The correction algorithm developed by Move makes it extremely independent of mounting errors. By processing the collected data it is possible to calculate the deflection of the structure with respect to a baseline. It also mounts a temperature sensor in order to relate thermal excursion and static deformation. Ideal for static monitoring of large structures and static load tests.

Applications

Building Monitoring

Monitor the static angular variation of the structural elements and to obtain the deflection of floors, walls and beams.

Bridge Monitoring

Monitor all the static parameters of a bridge as pier rotations or span static deflections.

Railways Monitoring

Monitor the longitudinal deflection and the transversal deformation of the rail track.

Geotechnical Monitoring

Monitor all the slow movements for measuring horizontal displacement, lateral displacement, settlement and heave.

The Triaxial Tilt Monitoring sensor is a highly accurate and exceptionally stable three-axis wireless Tiltmeter. Variable and remotely configurable sampling rates, a rugged design and a battery life of up to 8 years make this wireless Tiltmeter suitable for many environments and solutions. The wireless Tiltmeters transmit accurate readings from the site via the LoRaWAN wireless communication protocol via a Gateway.
You can view and interact with your data online using the Move Cloud Platform. There are multiple data processing and correlation algorithms developed by Move. It is possible to calculate the deflection of the structure with respect to a baseline. It also mounts a temperature sensor to relate thermal excursion and static deformation. Ideal for static monitoring of large structures and static load tests.

Easy installation of the Move wireless monitoring system
The installation of an entire wireless sensor system on site is quick and easy: simply mount each device with at least two screws on the structure you want to monitor and power the LoRaWAN Gateway. You can configure the entire system remotely, before, during or after installation, using your laptop or tablet. After assembly and setup, the Move wireless monitoring system will start measuring and you can start monitoring remotely.

Operation of the Move wireless monitoring system
The wireless sensor system automatically communicates the measurement data via LoRaWAN with the on-site Gateway which in turn sends the received data via 4G or LTE to the online servers. The Move Cloud Platform is the cloud-based web tool that allows you to access, view and export your measurement data and configure the settings of the entire sensor system. You can access the Move Cloud Platform 24/7 from any location or device around the world. One of the main advantages of the Move Cloud Platform is that it offers remote access to measurement data and allows remote configuration of all installed sensors. This saves time and labor. In addition, you can analyze the measurement data using processing algorithms included in the service. Perform complex calculations, correlations and analyzes automatically and effortlessly. With the touch of a button, you can export measurement data in CSV format. You can also easily configure alerts to multiple recipients who will receive threshold cross notifications via email.

Easily install the entire system on the structure without the use of wiring.
Configure all wireless sensors quickly and remotely.
View real-time measurement data wherever you are, on any device, 24/7.
Process the data collected through the implemented algorithms.
Constantly monitors the operating status and signal quality of the system remotely.
Customize your alarm notifications and receive overrun notifications by email.
Optionally, you can integrate data on your platform using an MQTT bridge, FTP or through API calls.
