Traditional methods of concrete quality control, like cube or cylinder crush testing, have always been slow, costly, and not fully reliable. These destructive tests often delay schedules and don’t reflect the real in-place curing conditions of a slab, which can lead to premature formwork removal or overstressed structures. The challenge has grown even sharper with the use of low-carbon mixes that cure differently. That’s why Danterr brings contractors Converge Signal®, an AI-powered solution that replaces uncertainty with data you can trust.

What is Converge Signal®?
Converge Signal® is an embedded, wireless concrete monitoring sensor designed for in-pour use. Once installed, it continuously tracks curing with precision, feeding temperature and maturity data into the ConcreteDNA® platform. This isn’t just another gadget; it’s a digital concrete testing alternative that helps contractors make faster, safer, and more sustainable decisions.
Signal® is ideal for high-rise projects, infrastructure works, and compliance-driven builds where accurate concrete temperature monitoring equipment is non-negotiable.
Converge Signal® Product Units
At Danterr, we supply the complete Converge Signal® system. Each unit has a specific role, and together they create a powerful concrete monitoring sensor network:
- Signal Sensor (No Connector): Single-use sensor for direct placement.
- Signal Sensor +™ Connector: Sensor with a connector for thermal tails when deeper readings are needed.
- Signal Software License (CE or NC) – Required for activation and data access
- Activation Magnet: Used to initiate sensors on-site.
- Single Probe Thermal Tail: Measures multiple depths and critical points in a pour.
- ConcreteDNA® Platform: Desktop and mobile dashboard for live strength and temperature insights.
- Signal Live Hub™ (Hardware): Collects wireless data from sensors embedded in the pour.
- Signal Live Hub™ Software (Annual): Cloud-based subscription for real-time monitoring.
Together, these units form a smart concrete sensor system that reduces reliance on labs and keeps projects moving.

How Converge Signal® Works
The process is straightforward:
- Signal Sensor +™: Register the Signal Sensor +™ on the ConcreteDNA® app and attach it to the rebar of your concrete pour using a cable tie. It will measure your concrete strength and temperature.
- Multi Probe Thermal Tail: Attach a Thermal Tail to your Signal Sensor +™ and register it using the ConcreteDNA® app. Place the probe at your desired measurement points.
- Signal Live Hub™: Turn on the Signal Live Hub™ and attach it to hoarding or an elevated position within 15m of your Signal Sensor +™. It will automatically collect data from the Signal Sensor and transmit it to ConcreteDNA®.
- ConcreteDNA Mobile and Web App: Use the ConcreteDNA® app to manually collect data over Bluetooth from the Signal Sensor +™. Concrete strength, temperature, and AI milestone predictions can be viewed in real time.
This integration eliminates the guesswork of traditional testing and acts as a predictive concrete curing tool.

Switching to Signal® unlocks value across multiple fronts:
- Faster decisions – Confidently shorten timelines with real-time data.
- Improved safety – Reduce the risk of collapse from premature loading.
- Reduced waste – Limit destructive testing and lab work.
- Sustainability – Better support for low-carbon mixes.
- Compliance-ready – Automatic reports aligned with ASTM C1074, NSW T382, and VicRoads 610-16m.
Signal® proves that concrete data sensors can deliver both safety and efficiency.
When Should You Use Converge Signal®?
Converge Signal® is best suited for projects where in-pour accuracy and real-time data are critical. Because the sensors are embedded directly into the concrete, you get precise strength and temperature readings without relying on lab cubes.
Ideal for:
- High-rise construction: Accurately tracking core wall or slab maturity to optimise cycle times.
- Large pours: Infrastructure works like bridges, airport runways, or precast yards.
- Civil projects with compliance needs: When QA records must demonstrate alignment with AS 3799, NCC, or state authority requirements.
- Fast-track programs: Where every day saved on formwork or stressing directly impacts budget and schedule.
Reliable, in-pour curing data that helps you strip formwork up to 40% faster and keep projects moving
Conclusion
Converge Signal® represents the future of wireless concrete technology in Australia; a system that gives contractors the data they need to build faster, safer, and greener. By embedding sensors directly into the pour, Signal® delivers unparalleled accuracy in tracking concrete temperature monitoring and strength gain, while simplifying compliance and reporting.
At Danterr, we supply not just the products but also the technical support to ensure your project benefits fully from this technology.
