reliability where there is insufficient information on the composition
of the screed.
Handling
For the measurement, a hole with a diameter of 7 mm or 8 mm
(flex) mm and a depth of at least 40 mm is drilled. The drilling depth
depends on the required measurement depth or screed thickness.
Before making the measurement in the hole, it should be carefully
cleaned of drilling dust and blown out. There must be no free water
in the hole. To prevent an exchange of air in the hole, it should be
sealed.
The equilibrium moisture content in the hole is indicated after
approx. 30 minutes, given temperature equilibrium (same
temperature in material being measured and the sensor tube
sensor).
Damage to the sensor
The sensor can be made irreparable by various mechanical and
environmental influences. These include in particu lar:
- direct contact of the sensor with the fingers
- direct contact with solid or sticky materials or objects
- measurement in atmospheres holding solutions, oil vapours or
other high levels of contaminants
Measurement errors
Measurements under 20 % r.h. and above 80 % r.h. should not be
carried out over a long period where possible (continuous
measurements). Other false measurements can arise from
