Taking routine nip impressions can help identify:
There is no "one-product-fits-all" approach but depending on your application needs Tekscan offers three solutions:
Fujifilm Prescale™ Film
single-use nip impression paper
Primary Use: Maintenance Tool
Also known as nip impression paper or a Fuji impression, Prescale film is used to measure pressure between nip rolls and calender rolls.
multi-use nip pressure measurement system
Primary Use: Instrumentation Setup
A powerful, versatile tool that accurately measures and analyzes dynamic contact pressure between rolls.
advanced nip pressure alignment tool
Primary Use: Maintenance & Setup Tool
The NPAT™ captures nip footprints and relative pressure distribution between nip rolls.
Nip impression paper is used to measure contact pressures and is as easy as passing the film through the nip rollers. The film structure consists of micro-encapsulated color forming and developing material. When pressure is applied to the film, a red color impression is formed in varying density according to the amount of pressure and pressure distribution.
I-Scan is a versatile solution for optimizing a process or manufacturing parameters. The I-Scan nip impression sensor is placed in the nip for real-time roller pressure measurement. With a wide range of sensor form factors and data analysis tools in the software, I-Scan is a powerful tool for a research and development team to improve yield.
NPAT is an advanced, easy-to-use tool used to capture nip footprints and relative pressure distribution between nip rollers. The system utilizes a sensor made up of an array of thin and flexible pressure sensitive bands, which can be configured to match the size of an application.
