Near-infrared thickness measurement module Online thickness measurement of polyester film - Working principle
The near-infrared thickness measurement module uses the characteristics of near-infrared light being absorbed and reflected when penetrating polyester film, and calculates film thickness by measuring changes in light intensity at specific wavelengths. In online polyester film thickness measurement, the near-infrared thickness measurement module adopts a non-contact measurement method, does not damage the film surface, and has a fast response speed. The module supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and PET film production line control systems, and has automatic calibration and fault self-diagnosis functions.
Near-infrared thickness measurement module Online thickness measurement of polyester film - Application scenarios
The near-infrared thickness measurement module is widely used in PET film, APET film, and PETG film production lines. In online polyester film thickness measurement, the near-infrared thickness measurement module can be fixedly installed at the extruder outlet, stretching zone, and before winding to collect thickness data in real time. The module can be linked with extruders, stretching machines, and winding systems to achieve automatic thickness adjustment. For large PET film production lines, the near-infrared thickness measurement module can also form a multi-point monitoring network and upload data uniformly to the control room.
Near-infrared thickness measurement module Online thickness measurement of polyester film - Technical advantages
The near-infrared thickness measurement module has the advantages of non-contact operation, high precision, and good stability. In online polyester film thickness measurement, the near-infrared thickness measurement module adopts a long-life light source and anti-contamination optical design, suitable for long-term operation. The module supports remote calibration and fault self-diagnosis, making maintenance convenient. When selecting a near-infrared thickness measurement module, attention should be paid to the measurement range, accuracy, response time, protection rating, and output signal to ensure it meets the needs of online polyester film thickness measurement.
