Meter Drive from Vectral Linear Measurement

MasTec has been marketing Vectral ( Meter Drive ) for many years.

Do you have a need for rapid accurate long linear measurement? – accuracy of 0.1 or 1mm options speeds up to 10m/sec??

Do you need elevator, saw bench or machine position?

Vectral has a very nice digital solution.

Used extensively Wrold Wide

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 (1 mm resolution) and 50kHz per channel for Z.301 encoders (0,1 mm resolution).
