The highly innovative SR710reflectance gauge is a uniquesensor specifically designed toallow accurate, on-linemeasurement of thin coatings onmetal foils or metallised papers andplastics. Its clever opticalconfiguration minimises opticalinterference effects and its use ofintense mid infrared absorptionsallows the thinnest of coatings,such as lube layers on can stock, tobe easily and accurately measured.

SR710 infrared measurementexcellence benefits our customers

New technology introduced in the SR710ensures users achieve the highest accuracyand measurement speed, critical formeaningful control of a high speed productweb. Selective infrared technology meanssubtractive measurement is normallyunnecessary, offering a cost-effectivemeasurement solution eg. lube on lacquer.

The SR710 high speed measurement(ca. 7.5msecs), up to 10 times faster thanconventional NIR gauges, reducesmeasurement noise, improves accuracy andallows far greater cross direction (CD) andmachine direction (MD) resolution of theproduct coat weight. Reduced noise allowsoperation closer to the process target for amore rapid return on investment.

The SR710 uses our proven Dual DetectorReferencing technology, for unrivalled longterm stability, essential when used as aninput for process control. Gauge stabilityalso removes the need for costly “re-calibration”.

The SR710 features Virtual Full Spectrum(VFS) technology allowing moresophisticated calibration models to be usedfor improved robustness. New algorithmsused in the SR710 mean it is less affected

by substrate variations, which benefits usersby minimising ongoing calibration activity.

Multi wavelength operation allows selectivemeasurement of the key coating or barrierlayer without need for differentialmeasurement, keeping the installationsimple and cost effective.

Up to 4 measurements may be made in onegauge which can reduce cost and hardwarerequirements for multiple measurementapplications eg. multi layer extrusion coating.

SR710 gauges have SpeedCal pre-calibrations, which reducecommissioning and installation time. Theunique NDC Infrared Engineering filtertechnology also ensures that the SR710 isnot affected by ambient lighting, humidityor temperature.

SR710 delivers important processbenefits

On line measurement with the SR710 offersproven benefits which allow rapid paybackon your initial investment:

• Reduction in raw materials consumptionthrough not over specifying

• Reduction in scrap due to continuousmeasurement and knowledge of theprocess

• Reduction in start up and grade changetimes because on-line measurementallows rapid set up of the desired coatweight or moisture

• Enhanced product quality andconsistency by continual measurementand control of process

• Improved product performance through

accurate specification

Fully networkedintegrated systems

SR710 intelligence for flexibility andconvenience of installation

The SR710 is a networked, intelligentgauge, which can can be configured tomeet virtually any requirement. For stand-alone installations the SR710 can besupplied with a touch screen OperatorInterface, providing local control.

Scanning and profile display systemsSR710 is designed to be scanned at highspeed and can be integrated into the NDC Infrared Engineering family ofsystems. The Windows NTTM based systemcan display multicomponent profiles frommultiple gauges

SR710 The lowest cost of ownership The SR710 does not require any routinemaintenance. Active diagnostics continuallymonitor the electronics, lamp and motorand an integral sensor protects the gaugefrom excessive temperature.The system automatically reports anyactions required.

The SR710’s integral Window ContaminationMonitor checks the status of the gaugewindow. Should any residues become

excessive, the system alerts the operator.Servicing is extremely easy due its modularconstruction concept.

These features add up, long term, to the SR710 offering the lowest cost ofownership measurement solution in themarketplace.
