Product Introduction
Near-infrared thickness measurement system for online film thickness measurement - Product Overview
The near-infrared thickness measurement system is a non-contact thickness detection system used for online film thickness measurement. Search keywords: near-infrared thickness measurement system, online film thickness measurement, near-infrared thickness gauge. The system is fixedly installed on the film production line and can continuously detect the thickness of medical film, industrial film, and photosensitive film, making it suitable for the medical and imaging industries. In online film thickness measurement, the near-infrared thickness measurement system can reflect thickness changes in real time, helping enterprises control product quality and reduce raw material waste.
Near-infrared thickness measurement system for online film thickness measurement - Working Principle
The near-infrared thickness measurement system uses the characteristics of near-infrared light being absorbed and reflected when passing through film, and calculates film thickness by measuring changes in light intensity at specific wavelengths. In online film thickness measurement, the near-infrared thickness measurement system adopts a non-contact measurement method, does not damage the film surface, and has a fast response speed. The system supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and film production line control systems, and has automatic calibration and fault self-diagnosis functions.
Near-infrared thickness measurement system for online film thickness measurement - Application Scenarios
Near-infrared thickness measurement systems are widely used in medical film, industrial film, and photosensitive film production lines. In online film thickness measurement, the near-infrared thickness measurement system can be fixedly installed at the outlet of the casting machine, the drying line, and before the slitting machine to collect thickness data in real time. The system can be linked with the casting machine, drying line, and slitting system to achieve automatic thickness adjustment. For large film production lines, the near-infrared thickness measurement system can also form a multi-point monitoring network and upload data uniformly to the control room.
Near-infrared thickness measurement system for online film thickness measurement - Technical Advantages
The near-infrared thickness measurement system has advantages such as non-contact operation, high precision, and good stability. In online film thickness measurement, the near-infrared thickness measurement system uses a long-life light source and an anti-contamination optical design, making it suitable for long-term operation. The system supports remote calibration and fault self-diagnosis, making maintenance convenient. When selecting a near-infrared thickness measurement system, attention should be paid to the measurement range, accuracy, response time, protection rating, and output signal to ensure it meets the needs of online film thickness measurement.
