Static, Nip Impression PaperEZ-Nip® is a thin color changing pressure activated paper used to detect uneven nip rollers in paper making and converting machinery. EZ-Nip® determines the actual working, static nip width between two mating rolls. The paper immediately changes color upon the application of pressure, enabling the user to easily analyze/measure the nip "footprint" (nip width) both visually or, for more intense scrutiny, with a ruler or micrometer. EZ-Nip® is a self contained single sheet system making it useable by just one person, and can easily be encased for waterproofing purposes. |

Portable, Electronic, real-time Nip Impression DeviceTake instant readings of nip for printers, spools or rollers at the point of production or in the workplace using our P-Nip® portable device with its flexible sensor element. This real-time nip analysis system can evaluate nip rolls under 70 inches in length and with a nip width from 1/16 inch - 1/2 inch. The ability to register multiple readings makes P-Nip® an invaluable tool for Quality Control in the manufacturing process or for the purposes of Quality Assurance with installed products. |

Static, Electronic, real-time Nip Impression SystemWith Sigma-Nip® you are able to calculate and record nip width at multiple points across your rollers face length in real-time with unprecedented speed, accuracy and repeatability. The new Sigma-Nip® system is not only more accurate, but can record higher pressures than ever previously attainable. Sigma-Nip® consists of a series of thin-film resistive ink pressure transducers on a carrier sheet. As this carrier sheet is loaded between your rollers the Windows-based software assimilates the readings into easily interpretable graphical images - all in real-time. |

Dynamic or Static Nip Impression FilmPressurex® film is useful in a large variety of applications including measuring nip pressure and roll contact pressure. The film aids in determination of uniform loading in a press's cross direction, as well as improving felt and cover life and consistent web compaction. Both dynamic and static impressions can be taken. Pressurex® will ensure parallelism between nipped rolls during roll changing as well as during routine downtime. The film is also ideal for determining crown correction, revealing damage to roll coverings and indicating roll wear. Precise PSI can be determined by comparison of the film's resultant color change to a color calibration chart (conceptually similar to interpreting Litmus paper) or by using one of several imaging systems that Sensor Products Inc. supplies. |

Nip Impression Film ScannerThe Auto-NIS imager is a revolutionary Windows-based system that enables the interpretation and analysis of Pressurex® and Fuji Prescale nip impression films. Using Auto-NIS® to analyze your nip impression films aids in ascertaining proper roller crowning and parallelism. Auto-NIS® can scan impression film of any length capturing all of the data across the film's width. A key feature of the Auto-NIS® software is the ability to view the entire nip length as a high resolution spectral image. Recorded information can be displayed in several different formats such as an XY graph of PSI and PLI versus roller cross directional length, moving average data and trend analysis. As Auto-NIS® scans and interprets your nip impression film, it assimilates the data into any easy-to-read graphical format. The final product of the analysis is a line graph portraying pressure versus nip cross direction as well as a moving average and trend analysis line. |

Electronic Nip Analysis SystemThe Tactilus Cascade® nip sensor system is the first of its kind. Tiny sensing points dispersed across the sensor surface collect data in the machine direction and cross direction of your roller set. The Tactilus Cascade® sensor transmits the collected data via RF to your laptop and allows for continuous monitoring and evaluation of any two mating rolls. The defining element of the Tactilus Cascade® that makes it so unique is its ability to clearly indicate actual pressure values across the roller interface – conventional systems capture data via a grid of sensor points that necessitate the user determining whether problems are caused by sensor alignment or roller misalignment. |
