Thermal Integrity Proﬁling data is collected by the Thermal Wire® cable system, which includes cables ﬁtted with digital thermal sensors spaced along the cable length. The Thermal Wire cables are attached to the reinforcing cage prior to concreting. In general, one cable is installed per each 305 mm of shaft diameter. A data logger is connected to each Thermal Wire cable, and automatically samples data from that cable at user selected time intervals, which happens typically every 15 minutes.
Temperatures obtained throughout the concrete curing process are then saved in each data logger. Following this, the data can be viewed at any time via data upload to the Cloud, once data collection begins. The expected temperature at any location is dependent on the shaft diameter, mix design, time of measurement and the distance to the centre of the shaft.
The critical time for recording data occurs during the hydration curing process until peak concrete temperature is reached. TIP data is collected by multiple data loggers attached to a foundation, sending the data via a modem to the Cloud.
Engineers and designers can see the data all at once, in real time, from any location.
