What is the composition of a strain gauge pressure sensor 2

Bridge circuit: Strain gauges usually exist in the form of resistors, connecting multiple strain gauges in a bridge circuit. Bridge circuits typically use either a Wiesbaden bridge or a full bridge circuit. When the strain gauge is subjected to pressure, its resistance value changes, causing a change in the voltage difference in the bridge circuit.diode

Signal conditioning circuit: The signal conditioning circuit is responsible for amplifying, filtering, and adjusting the voltage difference in the bridge circuit to generate usable voltage or current output. Such output signals can be processed by appropriate circuits and converted into digital or analog signals for use.diode

Output interface: The output interface of a sensor is usually a voltage signal, current signal, or digital signal. These signals can be further processed and utilized by connecting to external devices, data acquisition systems, or control systems.diode

2. Components:

The strain gauge pressure sensor consists of the following components:

Strain gauges: Strain gauges are the core components of sensors, usually made of metal materials, used to measure the strain changes caused by the force on an object.diode

Bridge circuit: A bridge circuit is a circuit that connects multiple strain gauges together to form a bridge. It can provide high-sensitivity measurement of small resistance changes generated by the corresponding transformer.diode
