Discusses the various sensors that can be used to measure temperatures at the high and low extremes of industrial processes. These include: mechanical sensors such as bimetal and expanding liquid thermometers; electrical sensors including resistance, thermistors, thermocouples and semiconductor; and optical pyrometers. Also describes the error effects that can be experienced and how these can be overcome.
Sensors allow windscreens to be inserted “on the fly”John Mortimer

Automotive windscreens are being inserted "on the fly" at the Dagenham, Essex, UK plant of the Ford Motor Company in what is being described as a world first in the technology. The technology reduces labour and capital equipment costs, as well as providing a more accurate "fit" of the windscreen in the aperture. The system uses robots and gripper-mounted specular reflection sensors to locate the windscreen aperture and insert the windscreens.

Technology advances in the field of temperature measurement have led to a huge variety of sensors and measuring instruments now being available for making accurate measurements at relatively low costs. This article takes a "back to basics" look at three of the most popular temperature sensor technologies and offers advice on how to avoid the many pitfalls and traps that often destroy the accuracy of a temperature measuring system.

In the last few decades the cultivation of cactus pears represents an important element in the economy of subtropical regions with scarce water resources. The increasing market competition from other countries has forced Sicilian producers to modernise the packing houses where the fruit is processed. The study carried out has shown that the technology employed in the newest packing lines is of a high level and that a low level of human, material and energy resources are necessary; moreover, packing and despining need further innovations. Trials conducted with an instrumented sphere IS100 has permitted critical points on the packing lines to be identified and to identify materials on which the fruit impacts during the processing.
