MACHINERY AUTOMATION PROBLEMS SOLVED (MV PRESQUE ISLE)

After three years service on the Great Lakes, the world's largest tug-barge combination wintered in Milwaukee for major refitting. Her engines needed overhauling, largely because of wear and damage resulting from thermal overload on some cylinders. The Presque Isle, owned by Litton Great Lakes Corp., had been equipped with comprehensive control and monitoring instrumentation so that her engines would operate with a minimum of attention, but the Alnor temperature-indication devices that monitor vital engine temperatures aged and began to give erroneous readings that served to conceal emerging engine problems. Alnor's new digital electronic unit, the Micro-8800 EGT monitoring system, has now been fitted. The system uses the computer-like capabilities of the microprocessor to combine all the essential EGT monitoring functions into a single compact instrument. The Micro-8800 continually scans up to 32 thermocouple zones at the rate of 1/sec. Order from BSRA as No. 49,315.
