LaserSpeed Non-Contact Technology
for accurately measuring length and speed
 Non-contact encoder
 Measures product directly
 Uses Laser Doppler
Velocimetry (LDV) technology
 Highly accurate, repeatable
product length and speed
measurements
 Better than .05% accuracy, .
02% repeatability
 Permanently calibrated

How LaserSpeed Works
Non-Contact,
Laser Encoder
The speed measurement
is made where the Laser
beams converge. The
LaserSpeed detects Laser
moving product Beams
regardless of shape, Standoff
surface, or color Distance

Application Examples
 Profile: Sanitary products
manufacturing
 Problem: Inaccurate length
measurement at slitter/rewinder
station due to mechanical
encoder errors – slippage,
debris build-up
 Solution: LaserSpeed encoder
provides near .05% length
accuracy
 Results:
 Eliminated 2% product give-
away
 Realized $40,000 savings/yr
 ROI in 3 months

12. Non-Contact Laser Measurement
Non-Contact Laser Gauge
Application Examples
 Profile: Packaging production
 Problem: Inaccurate cut control
due to tachometer slippage &
bounce, resulting in 90 ft of scrap
with each change-over (25 per
day)
 Solution: LaserSpeed encoder
accurately measures product
length & speed; provides precise
pulse counts to control cutters
 Results:
 No slippage errors
 Cuts to target length, even
during change-over
 Potential savings of $202K/yr
 Reduced maintenance costs

13. Non-Contact Laser Measurement
Non-Contact Laser Gauge
Application Examples
 Profile: Paper manufacturing
 Problem: Over-supplying and
shorting product by 2.5% due to
tachometer slippage; also
significant flying splice problem
 Solution: LaserSpeed encoder
accurately measures length on
take-up roll and controls tension
on unwind roll
 Results:
 Higher length & speed accuracy
 Reduced product give-away and
scrap
 Precise control of splicing speeds
 Decreased downtime
