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
