Description of measuring sensors
the individual temperature and humidity in the construction structures and in the internal environment were supplied by company TR instruments spol. s.r.o. Temperature sensors TG 68- 60 Pt1000 and Pt1000 TG7 are used for external and internal temperatures measurements of structure surfaces. Sensor HC2-C04 RH / T Rotronic (Fig.3.1) is used for temperature and relative humidity measurements in the construction of walls, roofs and ceilings. Temperature sensors Pt1000 and HC2-S RH/ T Rotronic (Fig. 3.2) are used for measuring the temperature and relative humidity in the in internal environments. Platinum resistance temperature sensors TR 087B-60 Pt1000 are used for soil temperature measurements.
Multi-channel measuring panel dataTaker DT80G with 4 CEM 20 modules , which records all measured figures in structures and in the internal environment in the default interval of 15 minutes, is used for long-term recording of measured figures. Figures of the temperatures in the soil are recorded in 1 hour intervals.
The measurement of geotechnical properties of the soil under the foundation slab is provided by means of ground pressure cells. Type 4800 measures the total voltage in earth backfills and type 4810 is used for the measurement of the contact between the soil and the surface of the concrete foundation slab.
Mechanical tension in the concrete foundation slab is provided by using an indirect measurement of deformation of resistance strain gauges type 4200.
