What is the composition of a strain gauge pressure sensor 3

Signal conditioning circuit: The signal conditioning circuit amplifies, filters, and adjusts small voltage changes in the bridge circuit to generate usable output signals.diode

Output interface: The output interface connects the sensor's output signal to external devices, data acquisition systems, or control systems for further processing and use.

Housing and Protection: Sensors typically include a housing to protect internal circuits and components from external environmental interference and damage.diode

3. Workflow:

The workflow of a strain gauge pressure sensor is as follows:diode

When an object is subjected to pressure, strain gauges produce small strains or deformations.

The strain of the strain gauge causes a change in its resistance value, which affects the voltage difference in the bridge circuit.

The signal conditioning circuit amplifies, filters, and adjusts the voltage difference in the bridge circuit.diode

The conditioned signal is output through the output interface in the form of voltage signal, current signal, or digital signal.
