OSM Safety Unit Monitors Motor-Rotation Speed Omron Scientific Technologies has introduced the G9SX-LM Low-speed Safety Monitoring Unit. Consisting of two proximity sensors and a G9SX safety controller with fault diagnostics, the G9SX-LM is a Category 3 (EN954-1), SIL 3 (IEC/EN 62061) certified redundant safety system that monitors and confirms motor-rotation speed to facilitate safe machine maintenance. The system can also provide standstill monitoring. The G9SX-LM allows an operator to access the machine for maintenance work while the machine is running at a safe, maximum set operating threshold of 10Hz. Should the motor speed exceed the preset speed, the G9SX-LM will stop the machine immediately. An optional A4EG Enabling Grip Switch provides an additional layer of safety protection that, if pressed or released, will also immediately stop the machine. The G9SX-LM is certified to all relevant North American and International safety standards and is engineered to deliver reliabl...

Emerson Process Management will apply its Plantweb digital plant architecture to a CEZ supercritical coal-fired unit being built at Ledvice power station in the Czech Republic. The new unit will reduce CO2 emissions by 20 per cent and is being built as a replacement for the older Ledvice units 2 and 3. When complete, it will be the largest coal-fired unit in the Czech Republic, with a generating capacity of 660MW. CEZ is one of Europe's top-ten power utilities, with a strong market position in the Czech Republic. As part of a coal power-plant modernisation programme, CEZ is investing in Ledvice and other selected power plants located near the Czech lignite mines. As well as delivering high-efficiency electrical power, the new unit at Ledvice will use the latest technology for flue gas desulphurisation (FGD) and ash handling to meet new European environmental standards. Operation of the new plant is scheduled for December 2012. CEZ named Emerson as the main automation contracto...

Sensonics has introduced the Sentry G3 machinery protection monitor, a high-performance signal conditioning unit. The G3 monitor builds upon the established range of Sentry protection systems developed by Sensonics and is designed to be a flexible and feature-rich turbine supervisory system. It provides a universal platform for the interfacing of various sensor types in compliance with the API 670 standard. Each of the units' four channels can be independently programmed to provide continuous monitoring and protection across a broad spectrum of measurement regimes, including vibration, expansion, temperature and speed. Sentry G3 utilises the latest DSP technology, so once a channel is set up and running, the resulting alarm relay and analogue output facilities are independent from the remaining module functionality, ensuring a scalable, high-integrity configuration. The unit has an integral colour LCD display and drive facility that provides immediate viewing and access to the...
