CC340T DIGITAL PULSE TACHOMETER 

 

GENERAL

The CC340T Pulse Tachometer is a shaft mounted design for mill applications requiring a rugged, low cost and precision design.

APPLICATION

  • One tachometer can be mounted onto various shaft diameters and styles
  • No shaft coupling required
  • Unlimited shaft end-float motion
  • No alignment required when installing or replacing - Tilt (run out) Adjustment available on larger   diameter shafts
  • Higher accuracy feedback signal. No error signal introduced from coupling alignment errors
