Large infrastructure and civil construction projects often extend well beyond the practical range of standard Bluetooth concrete monitoring systems. When monitoring locations are spread across bridges, highways, rail corridors or industrial facilities, collecting reliable concrete data can become increasingly difficult and time-consuming.
Converge Signal Long Range® is designed to solve this challenge. By combining embedded concrete maturity sensors, long-range wireless communication and the ConcreteDNA® platform, it enables contractors to monitor concrete temperature and strength development remotely across large construction sites. The result is better project visibility, fewer manual site visits and faster access to the information needed to make informed construction decisions.
Why Long-Range Communication Matters
On smaller projects, Bluetooth monitoring provides an efficient way to collect concrete maturity data. However, large infrastructure projects often involve multiple monitoring locations spread across hundreds of metres, making manual data collection less practical.
Signal Long Range® addresses this challenge by transmitting monitoring data through the Converge Gateway: Long Range®, allowing contractors to receive temperature and maturity information remotely across extensive construction sites. Instead of travelling between individual sensors, project teams gain continuous visibility from a central platform, helping improve efficiency and support faster decision-making.
Typical applications include:
- Bridges and highways
- Rail infrastructure
- Airports
- Mining projects
- Wind farms
- Industrial facilities
- Regional and remote construction
What Is Converge Signal Long Range®?
Converge Signal Long Range® is an embedded concrete temperature and maturity monitoring system designed for infrastructure, industrial and large-scale construction projects where monitoring locations extend beyond the practical range of conventional wireless systems.
Embedded within the concrete before placement, the sensor continuously records temperature data throughout the curing process. This information is transmitted to the Converge Gateway: Long Range®, then uploaded to ConcreteDNA®, where it is converted into real-time maturity, estimated strength and project progress data.
Unlike standard Bluetooth monitoring, Signal Long Range® allows contractors to monitor multiple pours from a central location without routinely travelling between sensors. This makes it particularly valuable for projects covering large geographical areas or multiple work fronts.
The system consists of three key components:
- Signal Long Range® Sensor – Embedded temperature and maturity monitoring.
- Converge Gateway: Long Range® – Collects data from sensors across the site.
- ConcreteDNA® – Displays monitoring data, maturity, strength estimates and quality assurance records.

How Converge Signal® Works
1. Install the Sensor
Before the concrete pour, the Signal Long Range® sensor is securely attached to the reinforcement and embedded within the concrete to begin monitoring temperature throughout the curing process. Sensor locations should reflect the areas where temperature and maturity data will provide the greatest value, such as critical structural elements, large concrete pours or sections where construction decisions depend on concrete strength development.
2. Monitor Concrete Temperature and Maturity
Once embedded, the sensor continuously records temperature data throughout the curing process. Depending on the selected configuration, compatible Thermal Tail™ options allow contractors to measure temperature at multiple points within the concrete element, providing greater insight into curing conditions.
The fully embedded design eliminates exposed cables while allowing monitoring to continue without disrupting construction activities.
3. Automatically Collect Data in ConcreteDNA®
The Signal Long Range® sensor wirelessly transmits monitoring data to the Converge Gateway: Long Range®, which automatically collects information from embedded sensors across the site. The gateway then sends this data to ConcreteDNA®, where project teams can review:
- Concrete temperature history.
- Maturity progression.
- Estimated in-place strength development.
- Project milestones and curing progress.
- Historical monitoring records for quality assurance.
Rather than manually downloading readings from individual sensors, authorised users can access monitoring information through a single connected platform.
4. Make Informed Construction Decisions
Continuous access to temperature and maturity data helps project teams make timely, evidence-based decisions throughout construction.
Monitoring data can support decisions such as:
- Formwork removal.
- Post-tensioning operations.
- Loading or opening concrete to traffic.
- Construction sequencing.
- Quality assurance reviews.
- Monitoring concrete strength development against project milestones.
All construction decisions should be made in accordance with the project’s approved maturity calibration, engineering requirements and relevant specifications.
Where Should You Use Signal Long Range®?
Signal Long Range® is designed for projects where distance, scale and site complexity make traditional short-range monitoring less practical. By combining embedded sensors, the Converge Gateway: Long Range® and ConcreteDNA®, contractors can monitor concrete temperature and maturity remotely across large construction sites, reducing manual data collection and improving project visibility.
While suitable for many concrete applications, Signal Long Range® delivers the greatest value on projects with widely distributed monitoring locations or where routine site access is challenging.
- Transport Infrastructure – Highways, bridges, rail projects and airports often involve multiple pours across large areas. Signal Long Range® enables remote monitoring from a central location, reducing the need to travel between monitoring points.
- Renewable Energy Projects – Wind farms, hydroelectric facilities and other renewable energy developments typically span large sites. Long-range monitoring helps contractors maintain visibility across dispersed concrete structures while simplifying monitoring workflows.
- Mining and Resources – Mining projects often involve remote locations and demanding site conditions. Signal Long Range® provides reliable access to concrete maturity data while reducing routine monitoring visits.
- Tunnels and Underground Construction – Tunnels and underground infrastructure can make sensor access difficult. When used with the Converge Gateway: Long Range®, Signal Long Range® supports reliable data collection across these complex environments.
- Industrial and Manufacturing Facilities – Large industrial facilities often include multiple foundations, slabs and equipment bases spread across expansive sites. Centralised monitoring improves project visibility while reducing manual data collection.
- Regional and Remote Infrastructure – Remote infrastructure projects benefit from continuous access to concrete monitoring data without frequent travel between monitoring locations, supporting more efficient project management.

Key Benefits of Converge Signal®
Signal Long Range® delivers more than extended communication range. By automating data collection across large construction sites, it helps contractors improve project visibility, reduce manual monitoring and make faster, evidence-based decisions throughout the curing process.
- Improve Visibility Across Large Sites – Monitor multiple concrete pours from a central platform, giving engineers and project teams greater visibility into temperature, maturity and strength development across the site.
- Reduce Manual Site Visits – Automatic data collection through the Converge Gateway reduces the need to physically access each monitoring location, improving efficiency on large and dispersed construction projects.
- Support Better Construction Planning – Real-time maturity data helps contractors make informed decisions about activities such as formwork removal, post-tensioning and subsequent construction stages based on actual concrete performance rather than estimated curing times.
- Simplify Quality Assurance – ConcreteDNA® automatically records temperature and maturity data, creating a digital project history that supports quality assurance, compliance and project documentation.
- Improve Site Safety – Remote monitoring reduces unnecessary movement around active construction sites by limiting routine visits required solely for data collection.
- Scale with Your Project – Whether monitoring several pours or an extensive infrastructure development, Signal Long Range® provides a consistent monitoring workflow that grows with project requirements.
