“A”-BASE ROTATIONAL ADAPTER

$1.00

The pulley attaches to the underside of the rotating shaft
with the shoulder screw. Please note the pulley orienta­tion as illustrated. The bracket connects to the “A” base
of the Rotating Platform or the Gyroscope and to the
RMS rod clamp.

The PASCO CI-6690 “A”-Base Rotational Adapter is
designed for use with the PASCO CI-6538 Rotary Mo­tion Sensor (RMS) or the PASCO CI-6625 Rotary Mo­tion Sensor for ULI. It is used to mount the RMS to the
“A” base of the PASCO ME-8951 Rotating Platform or
the PASCO ME-8960 Gyroscope. The Rotary Motion
Sensor provide s hi gher resolution than a Smart Pulley,
and precession and nutation of the Gyroscope can be plot­ted since the RMS keeps track of direction of rotation.
The adapter includes a mounting bracket, a shoulder
screw, a drive belt (o-ring) and a 3-step Pulley. The drive
belt links the 3-step Pulley mounted on the “A” base to
the 3-step Pulley on the RMS. For a one-to-one corre­spondence, connect the two pulleys using the o-ring on
the middle step of each pulley. Each revolution of the
Rotating Platform or Gyroscope corresponds to one revo­lution of the RMS. If desired, a 5-to-1 ration can be at­tained by putting the o-ring on the top or bottom steps.
