Abstract

This paper describes that send some signal from encoder attached to crankshaft of marine-engine to measuring instrument using power line modem(PLM) and display cylinder pressure, rpm and etc. on LCD. Conventional method that sends signal along the long signal line has some inconvenience from too long signal line length caused by huge volume of ship's engine. Power line modem can have short signal line from outlets to measuring instrument. Because it use exist power line for send signals, so it have low installation cost and could have good merits in job sites. Through this experiment, pressure in cylinder, engine rpm and etc. signals through PLM are well recognized at measuring instrument.
