Meterdrive Z.301A-0
Long-distance measuring systems - Measuring and positionning up to 500 meters. Reading speed : 10 meters per second.
Suitable for high-speed measuring and positioning, available in conventional linear encoder format or as an electronic tape measure.
OPERATION Plan of a linear encoder Z201 / Z301
The opto-electronic encoder accurately counts the number of slots in the perforated stainless steel tape at speeds up to 10m/s.
However, Meterdrive is not just a conventional linear encoder, and 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).
NO DESYNCHRONISATION Plan cross section of a linear encoder Z201 / Z301
The tape is guided in the encoder by 2 pairs of high-density polyethylene tape guides. Thanks to this system, the tape cannot move incorrectly, and therefore cannot lose step, as is the case with other measuring systems.
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.
Inside the encoder are 4 light-emitting diodes opposite 4 light-receiving diodes. The tape slides through the encoder, supported by polyethylene tape guides, and the receiving diodes are alternately covered and uncovered by the perforated tape. The encoder emits two incremental 90° phase-shifted signals (A & B). A warning signal E is emitted should the tape perforations become obstructed by dirt particles or if the power supply is insufficient.
The output signal can be used with any PLC or proprietary counter. Counters and PLCs have to take all edges of signals A & B into account (multiplication by 4) and must have an external reset. In order to use the high speed operation available with Meterdrive, counters and PLCs must have a counting frequency of 5kHz per channel for Z.201 encoders (1mm resolution) and 50kHz per channel for Z.301 encoders (0,1mm resolution).

TAPE Z.200-Z.300
The stainless steel tape is very flexible. making detailed adjustments unnecessary and thus facilitating use of the system (reduced time for engineering departments, installation,….). Thanks to the large size of its perforations (2mm), it is immune to almost all industrial environments.

The tape is usually stretched between two points. Up to 15m, no mid support is required. Over this length, a support should be positionned every 3-4 meters, or the tape should rest on a profile support for its entire length. When the encoder moves, it raises the tape approximately 20mm as it passes (1/2 the depth of the encoder with some leaway). When used with production machines, we suggest covering the tape with a U -profile to protect it from projections and chips.

Two types of tape are available
  • The Z.200 tape is intended for our Z.201 encoders, 1mm resolution. It is manufactured with an accuracy of ±0,1mm/meter.
  • The Z.300 tape is manufactured with an accuracy of ±0,03mm/m. It is the ideal choice for use with our Z.301 encoders if garanteed measures are necessary (ie. metrology).
All of our tapes are manufactured to attain their maximum precision with a tension of 50 Newtons, which can be easily applied with our Z.215 tension system.

For applications not requiring metrology but simply needing a positionning repeatability of 1/10thmm, it is possible to use our more economical Z.200 tape with the Z.301 encoders.

The Rollzam comprises the flexible tape coiled inside a housing and a spring to automatically rewind the tape. The detector head is thus static, protected against the environment, and gives the following benefits : easy mounting, fixed cabling, no tape support required. Standard length : 8 or 15m. The Rollzam base unit can be fitted with any of our (either the Z.201 or Z.301) encoders.

Ideal for : telescopic systems, measuring heights or levels……
