Mounting the Rotary Motion Sensor

The rod clamp fits rods up to 12.7 mm in diameter, such as the
ME-8736 45 cm Stainless Steel Rod, and the rod clamp can be
attached to the sensor in three different locations: at the end oppo-
site to the cable and on either side of the case.

Use the included hex key to loosen the two screws that hold the
rod clamp on the Rotary Motion Sensor case. The two screws do
not need to come out all the way; they are held inside the rod
clamp by small O-rings. Move the rod clamp to one of the addi-
tional mounting positions on either side of the case and use the
hex key to tighten the screws in place.

It is possible to mount the Rotary Motion Sensor horizontally on
a support rod with the Three-step Pulley facing up or facing side-
ways. You can mount the sensor vertically with the pulley facing
forward. The sensor can also be mounted on the short rod that is part of the Dynamics Track Mount Accessory
(CI-6692).

Mounting the Rotary Motion Sensor on a PASCO Track

Use the Dynamics Track Mount Accessory (CI-6692) to mount the
Rotary Motion Sensor on a PASCO track. Slide the square nut of the
Dynamics Track Mount Accessory into the T-slot on the side of the
track. Adjust the position of the mounting rod.on the Dynamics Track
Mount Accessory.

When mounted on a track as shown, a
Rotary Motion Sensor could be used to
measure the motion of a PASCO Cart as it
is pulled by a string suspended over the
Three-step Pulley of the sensor and
attached to a hanging mass.
