LAND, acknowledged leaders in the field of glass temperature measurement, have supplied the glass container and hollowware industry throughout the world with temperature measuring equipment for over 55 years. Today, LAND manufacture a whole range of measurement instruments specifically designed for the glass industry. Designed to the highest standards of quality and reliability to ensure accurate glass temperature measurements under plant operating conditions. The measurement of glass temperature at critical locations in the production process is essential for the full understanding and efficient control of glass manufacture and processing.
Efficient, high yield production of low loss, high bandwidth optical fibre for telecommunication demands precise measurement and control of preform temperature during the various deposition processes employed.
Plate and float glass temperatures during the cooling and annealing processes must be kept extremely uniform or with carefully controlled gradients. The temperature uniformity of the glass across the width of the bath in the float process is also important.
The LANDSCAN Glass Toughening System incorporates the LSPhd 5 series scanner which samples the glass surface up to 100,000 times per second using high performance optics allowing detection of even the smallest variations in temperature. The signals are transmitted via a single pre-assembled cable to a dedicated industrial processor unit which produces process control signals and provides data to the display PC.
