Micro Pressure Sensors & The Wheatstone Bridge Learning Module (LM) - Participant (Student) Guide - pdf.
This LM is an overview of the applications of micro pressure sensors and how the Wheatstone bridge is used as the sensing circuit for micro pressure sensors.
An activity - Modeling a Micro Pressure Sensor - allows the you to simulate the operation of a Wheatstone bridge circuit on a macro-sized pressure sensor, analyze your sensor and set up calibration curves based on its operation. A kit is available that contains most of the materials needed to complete this activity. This kit can be ordered through this website.
This learning module contains a pre and post-test, instructional unit, and two activities.
