DOUBLEFLEX Scale Tape
The DOUBLEFLEX-scale tape consists of two superimposed steel tapes� Both of them are divided by
a tension uncoupled sheen of oil which ensures the adhesion between the steel tapes� The incremental
track and one or more reference marks are applied on the upper steel tape� The lower steel tape is
equipped with a double-sided adhesive tape and can be mounted easily on the machine element�
The two steel tapes are uncoupled mechanically� This ensures that the upper steel tape can expand
independently of the lower steel tape due to thermal variations of the ambient temperature� By
reference of the ambient temperature and the expansion coefficient of the steel tape it is possible to
determine occurring length deviation of the increments� This allows to substract out the deviation of the
measurement results�
The DOUBLEFLEX scale tapes are available in two different types, “MV” and “MT”. They differentiate
oneself from the kind of the applied incremental and index track�
• MV
with asymmetric index track for 2-field scanning, suitable for Kit L2
• MT
with symmetric index track for 1-field scanning, suitable for Kit L4
