||Model HD-700-1 Dynamometer with Model 5400 Speed Readout and Model 5210 Power Supply. The most important characteristic of any measurement instrument is repeatability and accuracy. The Magtrol Dial Weight Dynamometer uses the combination of a Hysteresis Brake and gravity to insure constant, reliable results. The brake torque rise is directly proportional to applied current. The calibrated weight system provides readings in standard engineering units through the use of multiple torque range scales provided on each size dynamometer.Magtrol Dial Weight Dynamometers are a lower cost alternative to our standard (load cell) Hysteresis Dynamometers. The dial weight dynamometers are easy to operate, provide repeatable and accurate results, and will operate for many years with minimal maintenance. A Magtrol Dial Weight Dynamometer System can only operate manually in an open loop mode.
