Product Overview
The HBP411 series is a piezoresistive MEMS pressure sensor utilizing a Wheatstone bridge structure. Four resistors are diffused on a circular silicon diaphragm. When force is applied, the silicon crystal deforms, altering carrier mobility and resistivity, resulting in a linear voltage output. This sensor offers good linearity, repeatability, stability, and high sensitivity. Customers can utilize standard amplifier circuits for signal amplification and compensation to achieve high-precision measurements. Packaged in a standard DIP6 format, it is suitable for non-corrosive gas and liquid pressure detection across various applications.
