InfraPac electric IR moisture actuators
yield superior caliper and moisture
profile control. The smooth integration
of the ModuleJet, DCS (Distributed Control
System), and the Impact products
was largely attributed to Impact’s “totallyopen”,
distributed sub-systems plus
Ethernet and TCP/IP (network protocol)
communications directly from the scanners
and actuators. Wolfgang Griech,
Manager Development Controls for Voith
Sulzer Paper Technology, “In working
with various QCS (Quality Control System)
suppliers, we found the Impact system
far more open, which allowed us to
easily access the information we need
for optimum results.”
Although many system elements contributed
to the results at Consolidated
Papers, the three most notable were as
follows:
■ The combination of the ModuleJet
headbox and Impact’s weight sensor –
yielded excellent basis weight profiles.

■ The InfraPac moisture profiling
system – achieved amazingly good CD
moisture control.
■The direct Ethernet communications
from the Impact scanners to the mill’s
DCS and to the VSPT Profilmatic CD
weight controller allowed easy, fast
access to sensor information for operator
interface and control.
This successful effort demonstrated the
exciting potential created by the two organizations.
The Millennium family from Impact
Impact’s recently-introduced Millennium
family surely competes for “best of
breed” in papermaking measurement,
control and information-management.
Millennium introduces a new generation
of open system architecture that will
support development and growth well
into the next century. Millennium is
already proven, with eleven systems
installed. Customer-reported highlights
include:
■ An ultra-stable scanner and high-precision
weight sensor tripling the profile
measurement precision of other
gauges. Of course, this yields better
profiles. In the words of Rudolf
Münch, Manager of Process Controls
for Voith Sulzer Paper Technology,
“The Impact unfiltered basis weight
profile has better precision than the
filtered basis weight profiles from other
QCS systems. High precision profiles
are required to achieve the full
performance potential of ModuleJet.”
■ The broadest family of proven profiling
actuators and advanced CD controls
in the industry. The gas and electric
IR profiling/drying systems are especially
noteworthy in their ability to
address moisture streaks and drying
problems, and boost productivity.
■ Distributed “totally open” sub-systems,
using Ethernet TCP/IP, and oth-
