7. U COEFFICIENT
The thermal transmission coefficient of a wall is called “U” and characterizes the amount of heat which crosses a wall in
permanent regime, by time unit, surface unit and temperature difference unit between the ambiance located on both sides
of the wall. The thermal transmission coefficient is expressed in W/m²K and is the opposite of the total thermal resistance of
the wall. More the value is low, more the building is insulated.
➢ Connect the U coefficient module on the TM 210.
➢ Fix the temperature cables of the wire probe on the internal wall of the room or on the internal wall of the window
in order to obtain the surface temperature as indicated below.
➢
Select the
“Measurement”
tab with the navigation arrows.
➢ Press “OK”.
The device displays the surface temperature and the ambient temperature.
➢
Press the
“Functions”
key, select
“U coef.”
and press
“OK”
.
➢ Use the radiofrequency probe to obtain the external temperature. Put the Pt100 probe
on the outside to obtain the external temperature (see page for the pairing of the RF
probe 13).
The device displays the U coefficient, the surface temperature, the ambient temperature and the external
temperature.
For the measurements record, see chapter “Start and record datasets” page 16.
If you do not have a RF probe, you can enter manually the external temperature value : go to
“Functions” , select “U coef.” and press “OK” . Go to “Parameters” and set the temperature value
with the navigation arrows, press
“OK”
to validate.
