Principle of Operation - Force Sensor
How do the PASCO force sensors work?
- PS-3202 Wireless Force/Acceleration Sensor
- PS-2104 PASPORT Force Sensor
- CI-6537 Economy Force Sensor (ScienceWorkshop)
- CI-6746 Force Sensor (ScienceWorkshop)
PASCO Principle of Operation:
The PASCO force sensors employ four strain gauges epoxied to a binocular dual-beam made from annealed aluminum. The strain gauges are wired to form a full-bridge circuit that is driven by a constant voltage source.
The voltage across the bridge circuit is proportional to the applied force.
