Distributors required for French linear
encoder
Vectral of France is looking for distributors across the Nordic region and Ireland for Meterdrive, a conventional linear encoder based on the optical reading of a perforated tape.
Vectral of France, a manufacturer of linear encoders, has released a version of Meterdrive, a conventional linear encoder based on the optical reading of a perforated tape Output signals are now fully secured and the circuit is completely sealed, enabling the protection rating to be increased to IP 67

Vectral is looking for distributors across the Nordic region and in Ireland.
Meterdrive is designed for high-speed measuring and positioning.
The opto-electronic reader runs along the stainless-steel perforated tape and accurately counts the number of perforations, at speeds of up to 10m/s.
The tape is guided inside the reader head by two polyethylene guides and cannot, therefore, escape or detach from the counting cells.
Unlike other measurement systems, the Meterdrive cannot lose steps.
Meterdrive is watertight and is resistant to shock, as well as to environments that are subject to magnetic induction.
The absence of mechanical components, as well as the direct reading of the tape with wide slots, ensure that the system has an excellent lifespan and offers good resistance to wear.
The first Meterdrive systems installed in 1988 are still operating to this day.
Meterdrive also offers other advantages over traditional linear encoders.
The tape can be stretched between two points and does not need to be fixed accurately to a flat surface.
In this case, it is the head that moves.
The tape can also be wound in a similar way to a tape measure, and the reader head remains stationary.
This model - called Rollzam - is especially useful if two fixed points are not available to stretch the tape, as is the case for forklift trucks, table lifts, and for period inspection operations such as those carried out in nuclear power plants.
It is also possible to use the tape on a pulley with a counterweight and as a belt between two pulleys, as well as to move the tape held on a rod through a fixed head.
This solution is very useful for short movements (as is the case for hydraulic or pneumatic actuators).
