Product Introduction
Near-infrared thickness measurement transmitter for online thickness inspection of extruded sheets - Product Overview
The near-infrared thickness measurement transmitter is a non-contact thickness measurement transmitter device used for online thickness inspection of extruded sheets. Search keywords: near-infrared thickness measurement transmitter, online thickness inspection of extruded sheets, near-infrared thickness gauge. The transmitter is fixedly installed on extruded sheet production lines and can continuously measure the thickness of PP, PE, ABS, and PC sheets, suitable for the plastics and packaging industries. In online thickness inspection of extruded sheets, the near-infrared thickness measurement transmitter can reflect thickness changes in real time, helping enterprises control product quality and reduce raw material waste.
Near-infrared thickness measurement transmitter for online thickness inspection of extruded sheets - Working Principle
Near-infrared thickness measurement transmitters utilize the characteristics of near-infrared light being absorbed and reflected when penetrating extruded sheets, calculating sheet thickness by measuring changes in light intensity at specific wavelengths. In online thickness inspection of extruded sheets, near-infrared thickness measurement transmitters use non-contact measurement methods that do not damage the sheet surface and have fast response speeds. The transmitter supports 4-20mA, RS485, and Modbus outputs, can be connected to PLC, DCS, and extrusion production line control systems, and features automatic calibration and fault self-diagnosis functions.
Near-infrared thickness measurement transmitter for online thickness inspection of extruded sheets - Application Scenarios
Near-infrared thickness measurement transmitters are widely used in PP, PE, ABS, and PC extruded sheet production lines. In online thickness inspection of extruded sheets, near-infrared thickness measurement transmitters can be fixedly installed at the extruder outlet, calender, and before the winder to collect thickness data in real time. The transmitter can be linked with the extruder, calender, and haul-off system to achieve automatic thickness adjustment. For large extruded sheet production lines, near-infrared thickness measurement transmitters can also form a multi-point monitoring network, uploading data uniformly to the control room.
Near-infrared thickness measurement transmitter for online thickness inspection of extruded sheets - Technical Advantages
Near-infrared thickness measurement transmitters offer advantages such as non-contact operation, high precision, and standard outputs. In online thickness inspection of extruded sheets, near-infrared thickness measurement transmitters use long-life light sources and contamination-resistant optical designs, making them suitable for long-term operation. The transmitter supports remote calibration, fault self-diagnosis, and HART communication, making maintenance convenient. When selecting a near-infrared thickness measurement transmitter, attention should be paid to measurement range, accuracy, response time, protection rating, and output signals to ensure it meets the requirements for online thickness inspection of extruded sheets.
