Building thermal resistance measuring system
The high-sensitivity HFP01 heat flux sensors combined with the robust, high-resolution electronics ensure that TRSYS20 continues making meaningful measurements when other systems no longer perform; in particular at very low heat fluxes and low temperature differences across the wall. The matched thermocouple pairs allow measurement of temperature differences with an uncertainty better than 0.1 °C over the entire temperature range. Two measurement locations provide redundancy allowing the user to verify that the measurement results are representative for the building envelope component.
User interface: MCU as a web server
TRSYS20 is controlled via a PC. No software installation is required. The measurement and control unit (MCU) can be connected to a local area network (LAN) via ethernet or directly to a PC via USB. The MCU provides a graphical user interface in the form of a webpage that is accessible through a web browser. The graphical user interface allows the user to start and stop experiments; to monitor real-time heat flux, temperature and temperature difference measurement data; and to review preliminary results.
The system generates a data file, containing the measurement time, heat flux, temperature and temperature difference for the two measurement locations. The data file is stored in the MCU and can be downloaded through the graphical user interface. The user is responsible for the data analysis, calculating the R-, Λ- or U-value of the building envelope according to the ISO 9869 or ASTM C1155 standards.
