4.1 Mechanical mounting
Magnetic sensor failure
` When mounting pay attention to the IP type of protection (see chap-
ter 8 ).
` Do not open the sensor yourself.
` Avoid blows to the unit.
` Make any changes to the unit.
` Cable must be provided with strain relief. If necessary use drag chain
or portective sleeve.
Loss of measured values
` The tolerance and gap measures be observed over the whole measu-
ring length.
Exemplary sensor figures are valid for all sensor types unless described
separately.
4.2 Mounting the magnetic strip
External magnetic fields
Magnetic tape's magnetization gets lost. Any direct contact of the magne-
tic strip with magnetic fields (e. g. adhesive magnets or other permanent
magnets) is to be avoided. Sensor movements during power loss are not
captured by the follower electronics.
`
Protect the magnetic strip from impact by external magnets.
Solving bonding of the magnetic strip
` Remove foreign anti-adhesive substances including oil, grease or dust
by means of detergents that are preferably evaporating residue-free.
Suitable detergents include ketones (acetone) or alcohol offered for
instance as fast cleaning agents by the Loctite or 3M companies.
` For optimum bonding, the surfaces to be bonded must be dry and bon-
ding shall be carried out with maximum contact pressure.
` Observe a bonding temperature between 20 °C and 30 °C in dry rooms.
Deterioration of measuring accuracy
` Mount magnetic strip level with the mounting surface or distance to
be measured. Unevenness deteriorates measuring accuracy.
