Principle of Torque Meter

  1. Jul 5, 2009 #1
    I am going to measure the torque output of an diesel engine @ various RPM to understand the resistance of the gearbox connected.

    I wonder is there any guides for Torque meter DIY and the basic principle of a torque meter that can measure RPM + torque.

    Thanks in advence.

    Start reading through manufacturer's web sites. They are usually a wealth of information. Companies like LeBow are good starts. You also have to decide if you want a rotating or reaction meter. It sounds like you want a rotating one. All of the ones I have ever used did not have a speed signal output. That was measured separately.

    They mostly operate on the idea of angle of twist of a shft inducing a phase change between separate windings.

    Here's a good explanation of how the to torquemeters on the CH-47's engines (the T-55-L-712 in my day) works. Go down to the "Torquemeter Indicating System" section:
