Product Introduction
Near-Infrared Thickness Measurement Probe Blown Film Thickness Online Monitoring - Product Overview
Near-infrared thickness measurement probes are non-contact thickness detection devices used for online monitoring of blown film thickness. Search keywords: near-infrared thickness measurement probe, blown film thickness online monitoring, near-infrared thickness gauge. The probe is fixedly installed on blown film production lines and can continuously detect the thickness of LDPE, HDPE, and LLDPE films, suitable for the packaging and agricultural film industries. In online monitoring of blown film thickness, near-infrared thickness measurement probes can reflect thickness changes in real time, helping enterprises control product quality and reduce raw material waste.
Near-Infrared Thickness Measurement Probe Blown Film Thickness Online Monitoring - Working Principle
Near-infrared thickness measurement probes utilize the absorption and reflection characteristics of near-infrared light when penetrating blown film, calculating film thickness by measuring changes in light intensity at specific wavelengths. In online monitoring of blown film thickness, near-infrared thickness measurement probes adopt a non-contact measurement method that does not damage the film surface and offers fast response speed. The probe supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and blown film production line control systems, and features automatic calibration and fault self-diagnosis functions.
Near-Infrared Thickness Measurement Probe Blown Film Thickness Online Monitoring - Application Scenarios
Near-infrared thickness measurement probes are widely used in LDPE, HDPE, and LLDPE blown film production lines. In online monitoring of blown film thickness, near-infrared thickness measurement probes can be fixedly installed at the die head outlet, take-off rollers, and before winding to collect thickness data in real time. The probes can be linked with extruders, die heads, and take-off systems to achieve automatic thickness adjustment. For large blown film production lines, near-infrared thickness measurement probes can also form multi-point monitoring networks, uniformly uploading to the control room.
Near-Infrared Thickness Measurement Probe Blown Film Thickness Online Monitoring - Technical Advantages
Near-infrared thickness measurement probes have advantages such as non-contact, high precision, and fast response. In online monitoring of blown film thickness, near-infrared thickness measurement probes adopt long-life light sources and anti-contamination optical designs, suitable for long-term operation. The probe supports remote calibration and fault self-diagnosis, making maintenance convenient. When selecting near-infrared thickness measurement probes, attention should be paid to measurement range, precision, response time, protection rating, and output signals to ensure they meet the needs of blown film thickness online monitoring.
