Ultra-compact infrared camera for the metals industry
The OPTRIS PI 1M IR camera, available in South Africa from Instrotech, is especially suited to measuring the temperature of metals, as these exhibit a distinctly higher emissivity at the short measurement wavelength of 1.0 μm than at measure- ments in the previously conventional wavelength range of 8 to 14 μm. The advantage of temperature mea- surements with the new infrared camera lies in the large amount of information in an IR picture/IR video and the short reaction time of 1.0 ms for the output of temperature information of freely select- able individual pixels. The use of these image sensors allows a large dynamic range for temperature measurement so that the previously necessary use of relatively many and narrowly defined sub-ranges is no longer required. Intelligent measuring with a pyrometer is now possible thanks to the two-dimensional temperature recording of the Optris PI 1M. The large measurement temperature

range of 450 to 1 800 °C that the Optris PI 1M IR camera offers satisfies practically all demands in the fields of metal produc- tion and processing. Pertinent features of the Optris PI 1M IR camera include: • A highly flexible
CMOS detector with an optical resolution of up to 764×480 pixels. • A large temperature measurement range – without the need for sub-ranges – of 450 °C to 1 800 °C. • Frame rates of up to 1 kHz for fast processing. • Real-time output of middle pixel at a set- up time of 1.0 ms. • Inclusion of license- free analysis soft- ware and full SDK
Transfer chutes: a primary consideration
should be part of the design process from the very start.” Weba Chute Systems has, over the years, forged strong relationships with several leading EPCMs, and Baller notes that there is an apparent change in attitude towards the role of chutes in plant designs. Many EPCMs, he says, have seen the importance of getting a chute supplier involved at an early stage of the design process.
experience, a significant portion of plant downtime is generally attributable to transfer chutes, be it through blockages, spillage or high chute wear,” explains Baller. “That’s why chutes should never be considered an afterthought in plant designs. “An experienced chute manufacturer
The significance of correct chute de- signs to ensure efficient transfer of material in processing plants without blockages, spillage and with minimum wear cannot be emphasised enough. Yet, Engineering, Procurement and Construction Management (EPCM) con- tractors rarely collaborate with an expe-
rienced chute manufacturer early on in their plant design processes to ensure correct configuration of transfer points. This is according to Mark Baller, managing director of Weba Chute Systems, who warns that the consequences of insuffi- cient attention to transfer chutes in plant designs can be dire, as op- timum material transfer is seldom achieved at plant start-up. “The role of transfer chutes in a plant is traditionally underesti- mated. Based on our decades of
“Involving us in the early stages of plant designs eliminates the need for time consuming and costly modifications, which is often the case when a chute supplier is only consulted at a later stage of the process. Correct transfer chute designs eliminate unplanned plant stop- pages and production losses down the line, thus boosting revenues for the mine,” concludes Baller. www.webachutes.com
