Applications

Tips: Waterproof pressure sensor working principle

Pressure sensor is in a single product on the silicon diffusion of a Wheatstone bridge, the measured medium (gas or liquid) pressure to make the bridge wall resistance changes (piezoresistive effect), resulting in a differential voltage signal, the signal by a special amplifier, the range corresponding to the signal is converted into a standard analog signal or digital signal.
