Force sensors are a classic component of any physics lab and provide students with a chance to visualize motion in real-time. We have spent decades developing innovative force sensors and load cells that continue to push the boundaries of motion experiments. This page compares connectivity and applications for our ScienceWorkshop, PASPORT, and Wireless Force Sensors, as well as our load cells.

Sensor Interface Purpose
ScienceWorkshop Force Sensor 550/850 interfaces or legacy 500/750 interfaces
  • Higher sample rates up to 10 MHz (depends on interface)
  • Extra strain gauges cancel side-loads
PASPORT High Resolution Force Sensor Any PASPORT interface, 550, or 850
  • More sensitive: 0.002 N resolution
  • Maximum sample rate is 1000 Hz
  • Good for Hooke’s Law and Newton’s Third Law
Wireless Force Acceleration No Interface Required
  • Bluetooth 4.0 required
  • Same resolution as PS-2104
  • Measures force, acceleration, angular velocity
  • Maximum sample rate is 1000 Hz
PASPORT Force Any PASPORT interface, 550, or 850
  • Sample up to 5000 Hz on 550/850 interface
  • For more resolution, use PS-2189
  • For lower price, use PS-3202
PASPORT Force Platform Any PASPORT interface, 550, or 850
  • Measures normal force only
  • Good for measuring hang time when a person jumps
PASPORT 2-Axis Force Any PASPORT interface, 550, or 850
  • Measures normal force and tangent force
  • Excellent for measuring human walking
100 N Load Cell Any PASPORT interface, 550, or 850
  • Requires PS-2198 Six Load Cell Amplifier or PS-2206 Dual Load Cell Amplifier
  • For measuring loads in bridges or other structures made with PASCO Structures System
5 N Load Cell Any PASPORT interface, 550, or 850
  • Requires PS-2198 Six Load Cell Amplifier or PS-2206 Dual Load Cell Amplifier
  • Used with PASCO Structures System to measure smaller loads or to measure accelerations during bridge vibrations
