3 Overview

Torque and speed measuring device by the torque and speed sensor (hereinafter referred to as sensors) and the torque and speed measuring instrument (hereinafter Referred meter) components. Sensors in series to the measured rotating shaft, the torque and speed measurement by measuring instrument Measurement and display, and press the power function op display mechanical power. Its value is measured by measuring the torque sensor Torsional deformation of the torsion bar bearing the resulting signal is processed by the measuring device is converted to a torque value; measuring the rotational speed values with a frequency Counting method. The sensor device is generally divided into magnetic phase, photoelectric phase type, strain and so on.
