NDC Advantage Series Film, Extrusion & Converting NX TECHNOLOGIES a spectris company LOW ENERGY X-RAY SENSOR Model 312B-L for On-Line Thickness and Basis Weight Measurement Optimized for the Highest Performance NDC’s X-ray transmission sensor is designed to provide measurement performance that meets the exacting requirements of plastics extrusion, converting, calendering, nonwovens and textile applications. Three versions of X-ray sensors are available with different measurement capabilities. The high-resolution 312B-N-L offers excellent, narrow streak resolution and is suitable for most measurement applications. The ultra-high resolution 312B-XN-L offers even narrower streak resolution down to 0.5 mm. This small beam size enables sharp streak detection and is well suited for calendering applications. Its optimized geometry provides precise measurement through its ability to tune the X-ray tube for maximum resolution. The ultra low-noise 312B-W-L has a larger measurement patch size of 10 x 19 mm and offers excellent performance in applications such as nonwovens and thin films. The intelligent Low Energy X-ray Sensor is a new member of NDC’s portfolio of productivity solutions. Ideally suited for thickness measurements of light weight products such as stretch film, flexible packaging, battery separators and nonwovens, this X-ray transmission sensor brings a new level of performance while not requiring licensing in most countries. ► Extruded Film and Sheet ► Coating & Converting ► Calendered Products ► Aluminum Foil ► Nonwovens ► High reliability, fast and accurate measurement ► Wider operating weight/thickness range than comparable isotopic gauges ► Precisely regulated high-voltage supply for excellent measurement stability ► High scan speed (up to 500 mm/ 20 inches per second) ► Non-nuclear gauge minimizes regulatory requirements ► Low-energy X-ray requires minimal shielding ► Zero radiation hazard when powered down ► No degradation of measurement accuracy over time

The X-ray absorption properties of the material permit accurate measurement over a wide range compared to nucleonic sensors. NDC's X-ray tube features a stable, precisely-tuned power supply running at or below 5 keV that provides high signal-to-noise characteristics and optimum measurement performance. The high-voltage power applied to the X-ray tube cathode generates a stream of electrons that are accelerated toward a metal anode target. Once the electrons hit the metal target, X-rays are released at energies proportional to both the voltage applied and the nature of target material used. X-ray...
