Product Introduction
Near-Infrared Thickness Analyzer Online Analysis of Paper Coating Thickness - Product Overview
A near-infrared thickness analyzer is a non-contact thickness detection device used for online analysis of paper coating thickness. Search keywords: near-infrared thickness analyzer, online analysis of paper coating thickness, near-infrared thickness gauge. The analyzer is fixedly installed on paper coating production lines and can continuously detect the thickness of coating layers, coatings, and paper, making it suitable for the papermaking and packaging industries. In online analysis of paper coating thickness, near-infrared thickness analyzers can reflect thickness changes in real time, helping enterprises control product quality and reduce coating waste.
Near-Infrared Thickness Analyzer Online Analysis of Paper Coating Thickness - Working Principle
Near-infrared thickness analyzers use the characteristics of near-infrared light being absorbed and reflected when penetrating paper coatings, and calculate coating thickness by measuring changes in light intensity at specific wavelengths. In online analysis of paper coating thickness, near-infrared thickness analyzers use a non-contact measurement method that does not damage the paper surface and has a fast response speed. The analyzer supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and QCS systems, and has automatic calibration and fault self-diagnosis functions.
Near-Infrared Thickness Analyzer Online Analysis of Paper Coating Thickness - Application Scenarios
Near-infrared thickness analyzers are widely used in coated paper, white cardstock, and coated paperboard production lines. In online analysis of paper coating thickness, near-infrared thickness analyzers can be fixedly installed after the coating head, before drying, and before winding to collect coating thickness data in real time. The analyzer can be linked with the coating head, dryer, and winding system to achieve automatic adjustment of coating thickness. For large paper coating production lines, near-infrared thickness analyzers can also form a multi-point monitoring network and upload data uniformly to the control room.
Near-Infrared Thickness Analyzer Online Analysis of Paper Coating Thickness - Technical Advantages
Near-infrared thickness analyzers have advantages such as non-contact operation, high precision, and good stability. In online analysis of paper coating thickness, near-infrared thickness analyzers use long-life light sources and contamination-resistant optical designs, making them suitable for long-term operation. The analyzer supports remote calibration and fault self-diagnosis, making maintenance convenient. When selecting a near-infrared thickness analyzer, attention should be paid to measurement range, accuracy, response time, protection rating, and output signal to ensure it meets the needs of online analysis of paper coating thickness.
