TMS is a system to measure temperatures (T), calculate maturity (M) values at critical locations, such as those identified by B4Cast simulations, and estimate in-place strength (S) at early ages, based on a provided strength-maturity relationship. TMS provides remote monitoring capabilities similar to those described for HeatWatch.
Alarms stored in the TMS software alert the operator if preset temperatures or temperature differences have been exceeded. The TMS also permits automatic control of cooling or heating measures designed by B4Cast simulations.
Besides measuring temperatures, TMS can monitor other sensors that provide an appropriate electrical output. For example, TMS can monitor wind speed, relative humidity, barometric pressure, water levels, strains, corrosion parameters, and crack movement.
tms_1Thermocouples are installed at pre-established locations in the structure and connected to the data logger. The TMS software (same as used for HeatWatch) is installed on a PC with a Windows® operating system. Temperatures are recorded by the data logger at desired time intervals from the time of casting. The data are transferred to a PC, either by local area network connection to the logger or by a wireless cell phone connection, allowing remote monitoring of the temperatures and other measured parameters. Strength development at the thermocouple locations can be estimated through the use of pre-established strength-maturity relationship.
