Fibreglass batting is manufactured by pouring molten glass into a rotating spinner lined with a series of small holes. The molten glass, pushed through these small holes by centrifugal force, cools upon contact with the air and is blown downward by fans onto a moving conveyor. As it is falling, a binder material is sprayed onto the glass to allow it to stick together and form the batting. The thickness of the batting is determined by the number of spinners, the speed of the conveyor and the glass flow through the spinners. After the glass batting is formed, it is heated and rolled to final shape in a curing oven then packaged for shipping.
The glass flow through the spinner is strongly influenced by the spinner temperature. If the spinner is too cold, then the glass flow decreases, the fibres do not elongate properly and the holes may become clogged. If the spinner is too hot, then spinner life is shortened. Clearly process efficiency and effectiveness are heavily influenced by the temperature of the spinner.
The Williamson fibre-optic multiwavelength infrared thermometer is able to tolerate a signal dilution of as high as 6000:1 and is specially filtered for measurement through glass fibres. This feature allows the Williamson sensor to compensate for the severe optical obstruction associated with this application. In addition, the sensor uses multiwavelength technology and ESP filtering, an advanced signal conditioning to compensate for emissivity and optical obstruction.
