Sensor pair arrays measures liquid levels more reliably

Article Abstract:

The Optical Level Sensor uses total internal reflection from an array of LED transmitters and receivers to achieve more reliable measurements at lower cost than other competing technologies. This system is robust and can be used in any kind of fluid, transparent or opaque and uses data redundancy concepts to improve performance and avoids the need for frequent cleaning or maintenance.

Sensors monitor critical parts inside cabinets

Article Abstract:

Infra-red sensors based on thermopiles can be used inside electrical cabinets to monitor the temperatures of critical system components relative to ambient. The sensors are also suitable for monitoring temperature rise in bearing and gearboxes, which is generally considered to be an unequalled method of detecting problems before they have a chance to result in damage or failure.

Nuclear is no panacea to world problems

Article Abstract:

The reserves of high grade uranium ore are sufficient to deliver only a small fraction of the world's energy requirements. The present world nuclear power generating capacity is 350 GW and if it were to be increased to 1,500 GW, it would be necessary to find 15 million tonnes of uranium, whereas the viable uranium reserves are only about 4.5 million tonnes.
