On-line measurement technology specialist for the extrusion industry, NDC Infrared Engineering Ltd, is launching no less than three new thickness measurement gauges at the K'2010 Show; the revised FG710S NIR sensor, the TFG710S-ER (Extended Range) film gauge and the OptiMike Shadow LED sensor.
Already well established as the most effective way to achieve true thickness measurement of clear and pigmented BOPP Films of single or multilayer composition, the revised FG710S NIR Sensor now has extended measurement capabilities to include voided BOPP films, as well as micro-porous battery separator film using a single sensor.
Unlike beta or x-ray sensors, the FG710S measures thickness, not mass, of voided film, resulting in flat film and rolls. Its unique optics and measurement algorithms mean that a single gauge can be used for all types of film, including PET, PP, PE, PS, PVC, EVOH, PA, Surlyn, PMMA and more, measuring up to four different product constituents simultaneously. Without the re-standardization, source replacement, special scanner tolerancing or sensor cooling/conditioning needed for nucleonic-based gauges and the added benefit of measuring all film types, the revised FG710S offers significant cost benefits.
The new TFG710S-ER (Extended Range) film gauge has been engineered specifically for measuring a wide range of polyolefin based films on lines where multiple thickness ranges are produced. This versatile sensor uses a unique patented design, achieving a new level in on-line measurement speed, accuracy and performance, even on films less than 2 microns thick. Unlike the nucleonic alternatives, they are not affected by humidity, barometric pressure, gap temperature or airborne dust. They require no re-standardization, and can be fitted to standard scanning systems. The TFG710ER is a fantastic tool to assist processors trying to downgauge below 10 microns.
Also on show is the new OptiMike Shadow LED Sensor, which allows direct, single-sided thickness measurement of plastic sheet, foam and rubber products. Unlike laser triangulation gauges, it is insensitive to surface characteristics, color, or porosity.
