Near-infrared thickness measurement control module Online thickness control for polyethylene film - Working Principle
The near-infrared thickness measurement control module utilizes the characteristics of near-infrared light being absorbed and reflected when penetrating polyethylene film, and calculates film thickness by measuring changes in light intensity at specific wavelengths. In online thickness control for polyethylene film, the near-infrared thickness measurement control module adopts a non-contact measurement method that does not damage the film surface and has a fast response speed. This module supports 4-20mA, RS485, and Modbus outputs, and can be connected to PLC, DCS, and PE film production line control systems. It features automatic calibration, fault self-diagnosis, and closed-loop control functions.
Near-infrared thickness measurement control module Online thickness control for polyethylene film - Application Scenarios
The near-infrared thickness measurement control module is widely used in LDPE, HDPE, and LLDPE film production lines. In online thickness control for polyethylene film, the near-infrared thickness measurement control module can be fixedly installed at the extruder outlet, haul-off rollers, and before winding to collect thickness data in real time. The module can be linked with the extruder, die head, and haul-off system to achieve automatic thickness adjustment. For large PE film production lines, the near-infrared thickness measurement control module can also form a multi-point monitoring network and upload data uniformly to the control room.
