Tech Note 1008 Detail

Calculations for rack and pinion setting; small pulley and middle pulley; and the large pulley with the o-ring attached for the Rotary Motion Sensor.

Affected Products:

PS-2120 PASPORT Rotary Motion Sensor
PS-2008 SPARK Science Learning System

Problem/Symptom:
The SPARK system does not have an output for the rack and pinion setting; small pulley and middle pulley; and the large pulley with the o-ring attached.

PASCO Solution:
Distance for 1 rotation:
Rack and Pinion: 0.0798 m
Small Pulley: 0.0300 m
Middle Pulley: 0.0900 m
Large Pulley (groove): 0.1500 m (Built-in)
Large Pulley (O-ring): 0.1750 m

Calculator Functions for converting from large pulley (groove) distance to:
Rack and Pinion: pinion = [Linear Position(m)]* (0.0798/0.150)
Small Pulley: small = [Linear Position(m)]* (0.0300/0.150)
Middle Pulley: middle = [Linear Position(m)]* (0.0900/0.150)
Large Pulley (Groove): Large = [Linear Position(m)]
Large Pulley (O-ring): Oring = [Linear Position(m)]* (0.1750/0.150)
