Installation in asphalt:
The temperature around the sensor part and sensor tube must not exceed 80°C .
A wooden dummy or similar must replace the sensor while asphalt is poured
and cooled down . The conduit must be a metal tube that can withstand the high
temperatures .
Not OK! OK!
e) Ensure that the sensor tube is closed with the supplied
cap before the concrete is poured or the bricks are laid.
Make sure that air gaps are filled with cement.
f) Coil approx. 0.5 m of the sensor cable inside the tube. If
the sensor cable needs extension, see section 2.1.4.
