The LSV-2000 Laser Surface Velocimeter is the latest member of
Polytec's compact instrument class. Housed in the same casing as the
successful LSV-1000, the LSV-2000 determines the direction of motion
(forward or reverse), as well as, measures to standstill condition
(v=0). This makes it ideal for applications such as footage counting on
a take-up reel where the material may frequently start/stop, or for
applications requiring product positioning such as in cut-to-length
process lines. The direct, noncontact measurement of product length and
speed, coupled with the high precision, reliability and consistency of
the LSV-2000 enables users to fully optimize the production process and
hence, save costs.
The new optical system design offers depths of field and velocity
ranges that are independent of the sensor standoff distance. This leads
to significantly more application possibilities, especially for sensors
with short standoff distances. For example, in the event of varying
material thicknesses or varying pipe diameters, a shorter standoff
distance, with the new, larger depth of field, may well meet the
process requirements, rather than using a sensor with a long standoff
distance. Thanks to its compact design the LSV-2000 is perfectly suited
for use in small spaces, such as in C-Frame Thickness Gauges for
rolling mills or scanning systems in paper mills and film processing
lines. In addition, the LSV-2000 offers accessories for use in hostile
environments. Air wipes, water-cooled plates and rugged, fully
water-cooled housings are some of the accessories available for
applications in dirty, dusty or high temperature process areas.
When used as a footage counter, Laser Surface Velocimeters allow users
to reliably reduce process scrap through accurate and precise length
measurements, enabling process optimization to ensure a fast ROI.
Likewise, accurate and repeatable measurement of material speed at two
points (differential speed measurements) enables users to reliably
measure and control process parameters for achieving specified material
properties and quality, as is the case in applications such as mass
flow, elongation, stretch and draw.
