WHY USE THE NPAT?
• Take the guesswork out of machine set-up
• Capture real-time data to verify pressure distribution and nip contact
• Quantify tool integrity• Improve process and efficiency• It’s affordable and easy to use!
FEATURES & BENEFITS
Sensor band:
• Two sensor model resolutions to
support different roller sizes
• Standard band measures pressures
from 25-4500 psi (available in custom
pressure ranges up to 7500 psi)
Rugged Electronics:
• Single set of electronics covering a
large area
• Connected to a standard Evolution
handle; one USB connection to PC
• Protected by ruggedized enclosure
Sensor Band Interconnect:
• Bands are easily replaced and can be serviced
in-field
Carrier:
• Polycarbonate sheet that supports & aligns
sensor bands/connectors for easy alignment
when taking measurements
• Easily rolled up for storage & lays flat when
unrolled
• Includes a removable plastic sleeve that
protects from wet environments
Configurable Sensor:
• Large sensor with multiple sensor bands whose length and spacing can be configured to match the dimension of the nip being measured
• Bands can be spaced to show pressure
footprint and nip width across the roller
