Near-infrared thickness sensor Online detection of battery separator coating thickness - Working principle
The near-infrared thickness sensor uses the characteristics of near-infrared light being absorbed and reflected when penetrating the separator coating, and calculates the coating thickness by measuring changes in light intensity at specific wavelengths. In online detection of battery separator coating thickness, the near-infrared thickness sensor uses a non-contact measurement method, does not damage the coating surface, and has a fast response speed. The sensor supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and coating production line control systems, and has automatic calibration and fault self-diagnosis functions.
Near-infrared thickness sensor Online detection of battery separator coating thickness - Application scenarios
Near-infrared thickness sensors are widely used in ceramic-coated separator, PVDF-coated separator, and separator substrate production lines. In online detection of battery separator coating thickness, the near-infrared thickness sensor can be fixedly installed after the coating head, before drying, and before winding to collect thickness data in real time. The sensor can be linked with the coating head, dryer, and traction system to achieve automatic adjustment of coating thickness. For large separator coating production lines, the near-infrared thickness sensor can also form a multi-point monitoring network and upload data uniformly to the control room.
Near-infrared thickness sensor Online detection of battery separator coating thickness - Technical advantages
The near-infrared thickness sensor has advantages such as non-contact, high precision, and fast response. In online detection of battery separator coating thickness, the near-infrared thickness sensor uses a long-life light source and anti-contamination optical design, suitable for long-term operation. The sensor supports remote calibration and fault self-diagnosis, making maintenance convenient. When selecting a near-infrared thickness sensor, attention should be paid to the measurement range, accuracy, response time, protection rating, and output signal to ensure it meets the needs of online detection of battery separator coating thickness.
