Profile: Engine Monitor, Inc. specializes in alarm systems and control monitoring steering vessel mimic panels. Our product line includes alarm monitoring systems, shaft tachometer, dynamic positioning, engine order telegraphs, navigational light panels, integrated consoles and hydraulic power units. Our digital shaft tachometer system uses the latest digital technology to accurately & dependably measure the speed and direction of propeller shaft rotation. The shaft tachometer meter module can be installed in up to 6 locations on the ship. Its digital circuitry receives the output from the proximity sensors, interprets the signals, and displays both direction and speed. Our navigational light panels are small and light in weight. These have a enclosure which easily fits into most bridge panels, and can directly replace existing navigational light panels.
