Устройство для регулировки прижимных валков NPAT

Устройство NPAT (Nip Pressure Alignment Tool) предназначено для регулировки положения и прижимной силы валков

The Nip Pressure Alignment Tool™ (NPAT) is a complete nip pressure and force measurement tool that takes the guesswork out of machine set-up. By using real-time data, the NPAT verifies uniform pressure and nip contact. The tool measures and displays, in real-time nip widths between 6,35 mm and 215,9 mm.

NPAT System Rolled

There are several key features and benefits that ensure maximum usability for operators of the system:

• Configurable array of sensing bands

• Carrier to keep the bands/housing properly aligned during use

• Enclosure for the Evolution handle that protects electronics in more rugged applications

• Bands that can be easily replaced and serviced in-field

• Two sensor model resolutions to support different roller sizes

• Easily rolled up for storage

Verify Nip Pressure

Benefits of Measuring Nip Pressure:

• Clear visual representation of pressure distribution, nip width, and cross width

• Ensures proper alignment

• Prevents equipment and product damage

• Provides quantifiable and credible data

• Easily maintained in-field

NPAT Configurations

The NPAT is a system 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 your roller. The data provided by the NPAT ensures machine set-up and proper roll alignment resulting in a higher production yield.

There are six standard systems that each have their own spacing. All systems have a nip sensing width between 201,2 mm and 223,5 mm. The system is able to measure pressures of up to 4,500 psi.

*The 5700 Sensing Band (Max 13 bands) is used to make sensors between 457,2 mm and 6400,8 mm

**The 5707 Sending Band (Max 17 bands) is used to make sensors between 1524 mm and 10000 mm

Software

The software included has a simple user interface that allows for fast and efficient machine set-up. It has a streamlined set of features that allows the suer to easily identify nip uniformity. The pressure distribution across each band is displayed and can be saved as a snapshot of the image.
