Drivetrain Performance Testing

MRS-100 Series devices are wireless, so they can be used to measure torque, vibration, stress, and temperature of rotating parts around drivetrains, such as torque converters, flywheels, and drive shafts. MRS-100 Series devices operate at a high sampling rate, so that test data can be transmitted nearly in real-time—even when measuring high-speed phenomena.
