enhancements apply to two TMI models – the 49-86 and 49-87, and include advanced diagnostics and reporting functions. The models can now measure and
store multiple readings, which provides a cross-machine profile. At the same time, they can save up to 100 readings during a continuous measurement. A test summary screen
displays high, low, average and standard deviation for every series. The 49-86 has a range of 0-1.27mm and an accuracy of 1 micron. The range of the 49-87 is 0-12.7mm, while the accuracy is 5 microns. Both units have a resolution of 0.5 microns. Integrating GraphMaster PC-based
TMI has developed enhanced digital micrometers for thickness testing of very thin materials such as battery separators
software provides data collection, plotting and analysis with export capabilities for both models, and can profile a series of measurements creating a real-time plot of thickness versus interval, or distance.
IR gauge Last year, at K2016, NDC Technologies showed its latest FilmPro infrared gauge for the sheet, film and coating industries. The gauge uses advanced optical techniques to measure a wide range of film and sheet properties with high precision. The modular FilmPro gauge can measure the

thickness of a wide range of films – whether clear, voided, pigmented, cavitated, porous, translucent coloured or even black-tinted. It can also handle single- or multi-layer products including thin, biaxially- orientated films, cast films and CPE stretch films. It can simultaneously measure the individual thicknesses of up to six different layers in co-extruded films. NDC has also developed a new measurement model
combining discrete NIR filters and powerful gauging algorithms, which helps FilmPro to make direct film thickness measurement of products such as voided films and battery separator films – which had proved difficult in the past due to product density variation. Its unique design also provides the capability for measuring the oil content in PE battery films, including the wet cast film after the biax stretch part of the process.
Narrow focus At the forthcoming ICE USA exhibition, NDC will introduce its latest innovations for narrow web gauging applications. They include the 8000-Slim web gauging system with

compact SlimTrak scanner and ConvertIR gauge for fixed-point coat weight and moisture measurements. It will also show the Beta LaserMike LaserSpeed non-contact length and speed gauge. The 8000-Slim system with SlimTrak is a compact
measurement system for use on narrow-web lines. The SlimTrak scanner has a small cross-section footprint for tight-space installations and supports NDC’s most popular gauges such as the IG710 and SR710 infrared gauges or a Gamma Backscatter gauge. The system is built on NDC’s TDi quality management
software platform and delivers fast, real-time measure- ment and tight control of parameters such as thickness, coat weight, basis weight and moisture. It is available in a variety of scanner and gauge configurations. The ConvertIR gauge provides fixed-point, non-scan- ning on-line measurement of coat weight of coatings on films. The infrared gauge uses NDC’s optical filter technology. Because of its fast measurement speed, ConvertIR delivers continuous moisture or coat weight measurements enabling converting processes to be consistently measured and tightly controlled. It is available in two configurations: single gauge, with
Operator Interface (OI) for post dryer or conditioner moisture measurements or single-point coat weight; and dual gauge, with both instruments connected to a single OI to provide left and right coat weight measurements. Also on display is the Beta LaserMike LaserSpeed gauge, which measures the length and speed of any moving surface with better than ±0.03% accuracy and without contacting the product. It is an ideal solution for replacing error-prone, high-maintenance contact encoders, says the company, using laser-based technology to precisely measure both web and packag- ing products involving paper, film, sheet and foil. Typical applications include measuring product length and
