Goniometer Sensor


PASPORT Goniometer Sensor in use


PASPORT Goniometer Sensor

PASPORT Goniometer Sensor

PS-2137   - 

Can be connected to the knee, hip or elbow joints to measure angle changes during a variety of movements. For use with PASPORT Interfaces.
PASPORT Goniometer Probe

PASPORT Goniometer Probe

PS-2138   - 

An add-on probe to your Goniometer Sensor, this second probe allows you to measure the motion of two joints simultaneously.
PASPORT Angle Sensor

PASPORT Angle Sensor

PS-2139   - 

The Angle Sensor measures angle through measuring resistance. It has two ports to accept two goniometer sensors or the two probes in the joints of the human arm


Physics and physiology combine as students use their bodies as the experimental apparatus. The Goniometer can be connected to the knee, hip or elbow joints to measure angle changes during a variety of movements. Use with a bluetooth capable PASCO Interface for a compact, easy-to-use human motion lab.

This Goniometer Sensor includes one probe for measuring motion of a single joint. To measure a second joint simultaneously, purchase an additional Goniometer probe and plug it into the second port of your Goniometer Sensor.

Typical Applications

  • Angular Motion: Measure the angular position, velocity and acceleration for the arm or leg.
  • Tangential Velocity: Simply enter the correct radius and DataStudio will calculate the linear velocity for any point on the arm or leg.
  • Torque and Power: Use with a Force Sensor to measure the power generated by the arm or leg when lifting an object. Using software, integrate the power vs. time graph to find the energy used.
