There are two resolutions for our Rotary Motion Sensors. Low resolution and High resolution which leads to 4 times as many pulses for a given rotation. The max rotational speed is higher with the low resolution setting.
For Vernier-manufactured models (2008 and newer, order code RMV-BTD and order code GDX-RMS):
-Max angular speed with Low resolution setting: 30 revolutions/s
-Max angular speed with High resolution setting: 7.5 revolutions/s
