Search keywords: near-infrared thickness measurement probe, online polarizer thickness measurement, near-infrared thickness gauge. The probe is fixedly installed on a polarizer production line and can continuously measure the thickness of polarizers, retardation films, and protective films, making it suitable for the display and optical industries. In online polarizer thickness measurement, the near-infrared thickness measurement probe can reflect thickness changes in real time, helping enterprises control product quality and reduce fluctuations in optical performance.
Near-infrared thickness measurement probe for online polarizer thickness measurement - Working Principle
Near-infrared thickness measurement probes use the characteristics of near-infrared light being absorbed and reflected when passing through a polarizer, and calculate polarizer thickness by measuring changes in light intensity at specific wavelengths. In online polarizer thickness measurement, near-infrared thickness measurement probes use a non-contact measurement method that does not damage the polarizer surface and offers fast response speed. The probe supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and polarizer production line control systems, and features automatic calibration and fault self-diagnosis functions.
Near-infrared thickness measurement probe for online polarizer thickness measurement - Application Scenarios
Near-infrared thickness measurement probes are widely used in polarizer, retardation film, and protective film production lines. In online polarizer thickness measurement, near-infrared thickness measurement probes can be fixedly installed at the outlet of stretching machines, before laminating machines, and before cutting machines to collect thickness data in real time. The probe can be linked with stretching machines, laminating machines, and cutting systems to achieve automatic thickness adjustment. For large polarizer production lines, near-infrared thickness measurement probes can also form a multi-point monitoring network and upload data uniformly to the control room.
Near-infrared thickness measurement probe for online polarizer thickness measurement - Technical Advantages
Near-infrared thickness measurement probes offer advantages such as non-contact operation, high precision, and fast response. In online polarizer thickness measurement, near-infrared thickness measurement probes use long-life light sources and contamination-resistant optical designs, making them suitable for long-term operation. The probe supports remote calibration and fault self-diagnosis, making maintenance convenient. When selecting a near-infrared thickness measurement probe, attention should be paid to measurement range, accuracy, response time, protection rating, and output signal to ensure it meets the requirements for online polarizer thickness measurement.
