Newsteo Builder, Wireless datalogger with temperature and extensometer probe for concrete quality measurement

The concrete quality depends on the respect of the setting and curing of it. Newsteo has developed, in partnership with Lafarge R&D laboratory the Newsteo Builder, a datalogger to install directly in concrete. It allows recording and remotely check the temperature and deformation of concrete in the first hours of the setting and during the following years.
The Newsteo Builder can also be used for diagnosis sulphatic reaction, a concrete pathology.

Integrated sensors:

  • Temperature (reference BLR36)
  • Temperature and strain gauge  (reference BLR37). The strain gauge associated with the product is a coated Vishay gauge specially designed for inclusions in concrete.

Functionning

The Newsteo Builder includes temperature and deformation sensors.

It is directly buried (antenna included) into the concrete and it records the corresponding measurements in its embedded memory. When the user wishes, he downloads over the air all the measurements. With the long range antenna, the radio remains operational even under foundations or major works.

As all the measurements are dated, the user gets the complete history of the supervised concrete.

2 versions of the Newsteo Builder are available, with or without the shrinkage sensor.
