Fitness Technology is now installing the much higher resolution 600 pulse tachometers in the Woodway Force3 and Curve3 athlete-powered treadmills. Compared to the original 30 pulse tacho which had a resolution of 20mm the 600 pulse tacho has 20 times higher resolution at 1 mm per pulse. The resulting displacement, velocity and acceleration data is vastly superior in accuracy and validity. Evaluation of new high resolution treadmill tachometer.
