A Torsionmeter is used in the marine industry on vessel propeller shafts to measure the ship's performance including marine shaft horsepower, shaft torque, shaft RPM, total shaft revolutions, horsepower hours, and engine hours.

Why is it important to use a Torsion Meter?  Hillhouse Industrial & Marine, Inc's ShaftMaster torsionmeter systems will help maintain the vessel's performance by having historical data such as shaft horsepower, shaft RPM, shaft torque, total shaft revolutions, and engine hours, triggered by a RPM setpoint, and is available to compare on a monthly, daily, or even hourly basis.  We believe that it is the most reliable and accurate torsionmeter system on the market.

Why does your vessel need the ShaftMaster? or any ship torque sensors, ship horsepower sensors, or ship RPM sensors?  The only way to know a vessel's true horsepower is by measuring at the shaft with a torque meter.  It is very important to know the true horsepower before and after servicing the vessel in a shipyard.  Marine companies will pay for a simple sea trial to measure horsepower for more than what the permanent ShaftMaster  system costs.

We have installed the ShaftMaster on shafts as small as 2 inches in diameter and as large as 24 inches in diameter. Our torsionmeter is very user friendly, easy to calibrate, and very simple to install.
