Web Gauging Scanners for Thickness and Basis Weight Measurement

Reliability, modularity, ease of maintenance and low cost of ownership are of paramount importance. Thermo Scientific solid scanner designs assure accuracy and profile repeatability. Each scanner incorporates an embedded iBox processor and Linux operating system to provide fast, secure, robust measurement. 

The Thermo Scientific INTEGRA O-Frame Scanner is an intelligent, high-performance measurement frame specifically designed for lithium-ion battery electrode coating applications. The scanner design combines fast scan speed, precision head alignment and best timing belt profile to ensure maximum performance during the manufacturing process. Additional features including an adjustable roller assembly, angled passline and a side sensor mounting design to prevent particles from falling onto the web, as well as optional aluminum rollers to minimize sheet flutter and maintain tension, make the INTEGRA O-Frame Scanner an outstanding solution for battery coating applications. 

The Thermo Scientific INTEGRA C-Frame Scanner combines robust design and high acquisition speeds for best-in-class measurement performance in lithium-ion battery electrode calendering applications. Its single component aluminum construction is self-calibrating and provides high rigidity and temperature stability. Additional features include integrated precision guide rolls to ensure accurate, repeatable measurements in real time and a simple system configuration requiring minimal operator training. The INTEGRA C-Frame conforms to clean room specifications and is available in single or double frame options for narrow and wider lines.

The Thermo Scientific Mark III industrial scanner is a high performance measurement platform for the complete family of Thermo Scientific online sensors. The solid scanner design combines stability, reliability and maintainability to ensure maximum life cycle performance. It utilizes the proven exoskeleton design, incorporating a tubular steel structure, which provides high stability and isolates internal components from the environment. The rugged design makes the Mark III an excellent solution for demanding applications subject to high temperature, moisture, dust and fiber.

The Thermo Scientific L400 scanner is a high performance platform for many of the Thermo Scientific online sensors, where the size and payload capacity functions of the Mark III scanner are not needed, yet precision and accuracy are essential. Its unique design incorporates a precision weldment for strength and durability, as well as completely enclosed rails to prevent contamination of the sheet. The sensor drive uses a steel reinforced timing belt for strength and precision, while a digital encoder precisely controls the sensor position.

The Thermo Scientific L220 scanner is a high performance scanning platform designed to provide maximum performance within a minimal footprint. It is an extremely rugged scanning platform with a low profile designed to fit into reduced space with minimum machine modifications. The exclusive design needs no adjustments and is precision machined for extended lifetime maintenance of sensor alignment, while the rails are completely enclosed to keep them free of dirt and to ensure that material cannot drop onto the sheet.

The Thermo Scientific L220 Shadow scanner integrates a 6.25in (15.8cm) diameter stainless roll and is an adaption of our low profile L220 scanner, purpose-built for use with the Thermo Scientific ShadowMaster sensor. Its floating bearing design and stainless steel roll with inductive sensor minimizes the effect of temperature expansion and frame runout for the most accurate measurement possible. The L220 Shadow combines stability, reliability and maintainability to ensure maximum lifecycle performance and is an extremely rugged scanning platform with a low profile designed to fit into reduced space with minimal machine modifications. The distinctive design needs no adjustments and is precision machined for extended lifetime maintenance of sensor alignment, while the rails are completely enclosed to keep them free of dirt and to ensure that material cannot drop onto the sheet.

The Thermo Scientific C-Frame scanner is the ideal choice for installations with restricted space, harsh environments, or where the need to easily retract all of the measurement hardware from the passline is required. The C-Frame is available in a variety of configurations or application specific designs and incorporates heavy tubular steel weldments to ensure durability and guarantee the permanent alignment of the source and detector for optimum measurement performance.

The Thermo Scientific Box Beam scanner is engineered to provide cross machine scanning measurement for Thermo Scientific sensors that work in reflection mode. This proven scanner design combines precision, reliability and maintainability to ensure maximum life cycle performance.

This single-sided scanning frame is designed for demanding applications where durability and performance are required in extremely harsh environments and uses a unique box beam mount design to provide protection for the drive components from the harsh environment. The mount has purge ducts available to allow for positive pressure to prevent ingress of debris into the drive system.
