 Yarn/Wire Speed & Length Meter (»ç¼Ó±â)

yarn-wire_speed_lenght_meter.jpg (10668 octets)Multi-function Speed & Length Meter
YSL-2000

The YSL-2000 combines the functions of three separate instruments in one, easy-to-use device.

It accurately measures the speed and length of yarns, wires and other filaments using a unique "wrapper" roller. This precision roller directs the filament onto the low-inertia, U-grooved measuring wheel to maximize contact and eliminate filament slip and breakage.

The YSL-2000 can also be used as either a contact or non-contact tachometer to measure rotational speeds of shafts, motors, pulleys, etc. or linear speeds of moving surfaces such as conveyor belts, webs of paper or fabric, etc.

Features

  • Slide-on measuring heads make it simple to rapidly convert from on function to another
  • Accuracy of ±0.02%
  • Built-in memory for last, maximum, minimum values
  • Free NIST Certification and 2-Year Warranty
  • User-selected engineering units:
    Linear Speed: feet/min; meters/min; inches/min
    Length: feet; meters; inches
    Revolutions: RPM

Complete Kit

The YSL unit, two slide-on measuring heads (tachometer and yarn speed), cone tip, universal surface speed wheel with integrated funnel tip adapter, reflective tape, two AA batteries and operating instructions, all supplied in a foam-fitted, hard-plastic carrying case.
