ConvertIR

ConvertIR Coat weight thickness & moisture gauge

Overview

The ConvertIR is an on-line coat weight and moisture measurement gauge using near-infrared (NIR) non-contact principle. The gauge provides dependable, stable and accurate on-line measurement which allows the converting processes to be tightly and consistently controlled. The gauge is suitable for use in many types of converting processes such coating thicknesses of adhesives, water-based pigmented or clay coatings, wax coatings, polymer coating on paper, vinyl and PVC coating on paper and moisture in paper and board. ConvertIR has a wide range of connectivity including most modern Ethernet bus systems which means integrating more easily than ever into productions networks for providing real-time data exchange and for improving process control and efficiency.

Operating principle

ConvertIR works on the principle that water molecules (or organic based coatings) absorb a specific wavelength of infrared light. By pulsing light at known wavelengths and comparing the absorption rate to an internal reference it is possible to determine exactly by how much each wavelength is being absorbed. Using high speed signal processing the algorithm converts the infrared signals into an output that is proportional to moisture or coat weight thickness by means of a calibration algorithm. The measurement is unaffected by changes in process conditions such as particle size, product height temperature, ambient lighting and humidity changes.
