Tech Note 437 Detail

Principle of Operation - Force Sensor

Affected Products:

CI-6537 Force Sensor
CI-6746 Economy Force Sensor
PS-2104 PASPORT Force Sensor

Problem/Symptom:
How do the PASCO force sensors work?

PASCO Solution:

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.
