What is the composition of a strain gauge pressure sensor 1

Strain gauge pressure sensor is a common pressure measuring device used to measure the strain changes caused by the force on an object, and then convert them into electrical signals for output. The sensor consists of multiple components, including strain gauges, bridge circuits, signal conditioning circuits, and output interfaces. The following is a detailed introduction to the working principle and components of strain gauge pressure sensors.diode

1. Working principle:

The working principle of strain gauges is based on the strain effect, which means that when an object is subjected to external forces, it will undergo deformation or strain. Sensors infer the magnitude of pressure by measuring the strain changes caused by the force on an object. The specific working principle is as follows:diode

Strain gauges: Strain gauges are the core components of the DS90UB948TNKDRQ1 sensor, typically made of metallic materials. When an object is subjected to external forces, strain gauges will produce small deformations or strains. These strains will cause a change in the resistance value of the strain gauge.diode
