NOTE
For technical reasons, an additional allowance must be taken into account for the
magnetic tape length (across from the measuring distance):
• TTK70: ≥ 80 mm
Marking on sensor
required tape length = measuring section + 80 mm

NOTE
Mounting must be done level to the mounting surface or the distance to be measured.
Ripples always impair the measurement accuracy. Sufficient mechanical protection
must be ensured (e.g. against impacts and vibrations).
NOTE
To achieve optimal bonding, all anti-adhesive foreign substances (oil, fat, dust, etc.)
must be removed with cleaning agents which evaporate with the minimum possible
level of residue. Among others, ketone (acetone) or alcohol are good cleaning agents.
NOTE
The adhesive surfaces must be dry and the maximum possible contact pressure must
be used for adhesion. An adhesion temperature of 20 °C and 30 °C in dry rooms is
optimal.
NOTE
When adhering longer strips of tape, the protective film of the tape should be removed
in shorter sections to fix the tape. Then the tape is aligned. After alignment, the rest of
the protective film can be pulled out from the side while pressure is applied to the tape
at the same time.
