In business since 1984 and weathering the various economic and market ups and downs over the last 40 years, Hillhouse Industrial Marine Inc. have progressed to its current system: The Shaftmaster 6000, which provides shaft RPM, shaft horsepower, shaft torque, total shaft horsepower hours, total shaft kW/hr., total shaft revolutions, total engine hours and specific fuel consumption.
The system from Hillhouse is a PLC with a Micro SD chip for recording data in time (Typically) in five-second intervals, however can be changed for more or less intervals and can be triggered by a discrete input. Once the Shaftmaster 6000 has been calibrated, the system will stay in calibration as long as the sensors are not moved.
