ConSensor is an advanced concrete strength sensor. ConSensor simultaneouslycalculates the compressive strength of curing concrete in two ways: by the concrete’s weighted maturity and by its conductivity. The measurement data from these methods is available in real time on a secure web platform using a PC, tablet or smartphone. ConSensor can also send you text messages when significant thresholds are met.
ConSensor is ideal for most applications in concrete construction. ConSensor offers distinct advantages over other measuring systems by combining two measuring methods that together provide greater clarity about underlying issues. For example, a variance in strength measurements between the weighted maturity and the conductivity methods might indicate that the concrete mix is different or that the concrete was poured too late. ConSensor’s measurement data gives the construction team the information it needs to respond quickly and appropriately.
Unlike other systems, ConSensor employs 2 separate strength indicators:
Temperature, using the weighted maturity method (NEN 5970)
Electrical conductivity, which diminishes proportionally to the hardening of the concrete.
Two calibration curves determine the:
Relationship of compressive strength to weighted maturity
Relationship of compressive strength to conductivity
When a concrete mix is selected for the building site, the corresponding calibration line is automatically selected as well.
ConSensor equipment has been developed with and for experts in concrete construction. The system is robust, easy to use and usable anywhere: from underwater concrete to the tallest prefab residential tower in the world.
Users praise ConSensor’s ease of use and the level of insight ConSensor provides as the concrete hardens. Those who use ConSensor make fewer mistakes and work more efficiently, increasing job satisfaction along the way.
Intuitive web platform: It’s immediately clear how the web platform can be used, from creating a calibration curve to managing various projects: “It already feels familiar after using it once”.
Easy calibration: Creating a calibration curve on the web platform is an intuitive, straightforward process
Simple installation: With the push of a button, the system activates, and measuring automatically starts as soon as the concrete has been poured.
Reliability: When a device has to make a wireless connection through concrete with steel reinforcement, the signal has a hard time getting through. And when battery power gets low, you lose the signal forever. So only wired sensors can be used for long-term quality monitoring.
Convenience: It seems easy to just put a small device in the concrete without any cables and hassles, but then you have to get quite close to it to read it out. Using ConSensor’s wired devices with standard cable lengths of up to 10 metres, you can measure anywhere—even underwater—and the data is sent directly to the internet and available always, everywhere, and for everyone on the project.
Cost: The cost of our wired sensors is about 10% to 20% of the cost of wireless sensors. And why waste the electronics and battery? Putting the electronics outside the concrete saves resources and money.
