Electrode monitoring system for glass furnaces

Eurotherm DEL India offers an electrode monitoring system for glass furnaces with interactive touch-screen display, developed by FIC (UK) Limited of Penzance. This newly launched Electrode Maintenance Unit (EMU) continuously monitors and displays electrode performance, allowing wear or breakage to be picked up early enough to avoid refractory erosion or damage. The heart of the unit is based on Eurotherm"s versatile Visual Supervisor control system, providing a high level of operator information, with touch-screen display. The EMU allows glass production personnel to fully monitor and determine the state of wear of the electrodes at any time during the furnace campaign. Taking advantage of flash memory, it keeps a continuous record of electrode voltage and current, and is fully alarmed to alert operators of any problems detected with the electrodes. System versatility is such that electrode holder temperatures are monitored as well as furnace voltage and current parameters. Measurement of both electrode and furnace parameters is handled through an adjacent Eurotherm 2500 System, which provides high performance, high accuracy I/O routing from furnace thermocouples as well as electrode current and voltage transducers. This unit incorporates a number of unique hardware and software interactions that provide fast, accurate response times for analogue process control systems of the EMU type.
