Sentinel Splice (Joint) & Tearout Detection Unit Applicable To Any Web Fed Process: The Model 1088 Sentinel™ Splice Detector state-of-the-art splice detection technology consumes very little power while providing dependable and consistent splice (joint), tearout and web break detection on virtually any web process application. The Sentinel is designed to monitor from one to 16 or more webs of material and will detect any splice or joint that may exist within the web based process. It is applicable to manufacturing processes that require the culling out of splices or joints prior to shipment. As a control in subsequent conversion processes, it prevents damage to sensitive equipment. Examples of these include soft rolls, print heads, coater applicators and print blankets. Immediate detection, rejection and control of splices or joints creates savings of up to tens of thousands of dollars per annum.

Respond to Varying Conditions: Unaffected by printed surfaces, material color, grade changes and process speeds that challenge “photo eyes”, "Thru-Beam" and “ultrasonic devices”, the Model 1088 Sentinel™ Splice Detector designed as a capacitor treats the web material as a dielectric. Therefore immediate and sudden changes in material thickness due to splices, tearouts, and web breaks in the dielectric are instantly revealed as a change in capacitance. The Model 1088 Sentinel™ Splice Detector guarantees 100% reliable detection every day; every shift. The Model 1088 Sentinel™ Splice Detector is a self-calibrating system that is powered by +24VDC. It provides an opto-isolated, digital electronic output with a pulse width selectable for 1, 10 or 100 milliseconds. The re-designed alarm indicators are low power, low voltage LEDs that are clearly visible to machine attendants. The unit can be mounted anywhere along the web at any angle and either right side up or upside down.

Minimize Operator Intervention: The Sentinel is connected directly to PLC control devices or interfaced for activation of peripheral equipment such as audio/visual alarms, counters, sorters, coating head applicators, corona treaters, edge marking systems and reject gate controls. Modular in design, the new Sentinel requires 50% less energy to operate and can be equipped with the optional Model 4000 AutoTrack™ Control Technology; unique web edge tracking capability derived from custom sensing arms that provide process functions to advance/retard the splice detection unit automatically. The arms, precision machined, will not damage sensitive web materials and are made of light weight aluminum. Our unique edge tracking ensures your inspection device will track the web and will always be located in the “sweet spot” for reliable detection. The Model 4000 AutoTrack™ Control Technology will respond to changing conditions such as deckle (web width) changes automatically to ensure your inspection devices are always placed in the correct inspection area. This technology comes as a complete package measuring 4.5" x 4.5" x 12" (11.43cm x 11.43cm x 30.48cm) and has universal mounting holes in the base and the back. All of our splice detection technologies can be combined with our own Model 1280 Edge Marking Technology™ and Model 1122 Reject Gate Control Computer™ for completely unattended operation of your production equipment. The Return on Investment (ROI) is most often as little as 24 hours of operation.

Guarantee Product Quality: With thousands of installations worldwide, our inspection technologies have been effectively applied to ensure delivered product quality on tens of thousands of materials, coated and non-coated such as papers, films, nonwovens, textiles, and tapes. Our splice detection technologies can be installed on many types of machinery including sheeters, on and off machine coaters, extrusion laminators, supercalenders, rotogravure and flexographic printing presses, holographic processes, textile and nonwoven machinery.
