ObraLink Resistances

ObraLink Resistances automates the measurement of concrete resistance with advanced devices like Cibot and Rsense2, providing cost savings, visualization in BIM, and integration with ObraLink Control. This solution comprehensively addresses both construction control and resistance measurement, eliminating the need for manual data collection and allowing for real-time resistance measurement.

Concrete Resistance Measurement Technology Rsense2

Rsense2 Dimensions
The Rsense2 is an advanced device designed by ObraLink to measure the maturity and resistance of concrete. It is a sophisticated and innovative system that provides accurate and real-time information. This device consists of a probe and an electronics unit called Rsense 2. The probe connects to Rsense 2 on one end, and on the other end, it has a PT100 temperature sensor capable of measuring temperatures between -50°C and 500°C with an accuracy of at least 1°C. The Rsense 2 electronics unit is a reusable device, which, as it is not embedded in the concrete, significantly lowers implementation costs, as it can be reused many times. Rsense 2 operates under the LoRa (Long Range) wireless communication protocol, which allows the temperature data to be transmitted to a receiver located somewhere on the construction site.

The probe is the measurement cable that remains embedded in the concrete and transmits temperatures from the concrete to Rsense 2. Depending on the project, the length of this probe can vary from 2 meters to over 25 meters (for example, in projects with pile anchorages that need to be stressed).

Thanks to the use of the LoRa long-range communication protocol, when using the Rsense2 sensors, construction teams do not need to manually collect temperature data (for example, through a mobile application). The temperature/resistance data is automatically sent from Rsense2 to a receiver located on-site, which then transmits the data to the internet. This entire data flow is automatic, requiring no worker intervention on-site.

What makes Rsense2 unique?

• Wireless and automatic collection of resistance data, with no intervention from your team on-site.
• Longest battery life on the market, preventing you from needing to buy more sensors throughout your project (competitors only offer 2 months of battery life).
• Reusable, only the measurement probe is lost.
• Resistance data displayed on the BIM model.

What benefits do you get from using Rsense2?

• Reduce the time demand on your workers, as resistance data is obtained automatically.
• Accelerate the construction of your structural phase, as by measuring concrete resistance in real-time, you can deshutter early, post-tension sooner, or reduce the number of levels being stressed, also accelerating your finishing phase.
