The opto-electronic encoder accurately counts the number of slots in the perforated stainless
steel tape at speeds up to 10 m/s.
Meterdrive offers the user significant
benefits over other linear measuring systems: the
stainless steel tape can be stretched between two fixed points and does not need
to be fixed accurately to a flat base. In this case, the encoder is mobile.
Alternatively, the tape can be coiled as in a tape measure with the encoder
stationary. This solution, the Rollzam, is particularly useful if there is only one
fixed point for the tape, as is the case for fork lifts, table lifts or periodic controls
in nuclear power plants.
It is also possible to use the tape with a pulley and counterweight, as a belt between
two pulleys, or to move the tape through the fixed encoder. This last solution can
be very useful for short distances (such as pneumatic or hydraulic jacks).
Water and shock resistance, absence of mechanical parts
and direct reading via large tape perforations ensure that
the system has excellent life and wear characteristics.
Meterdrive is particularly useful as a replacement for conventional chain arrangements, pulleys, etc, where roller slip or wear can cause loss of positioning when using rotary encoders.
