Product Overview
The HBP411 series is a piezoresistive MEMS pressure sensor utilizing a Wheatstone bridge structure. Four resistors are diffused onto a circular silicon diaphragm. When force is applied, the silicon crystal deforms, altering carrier mobility and thus resistivity, resulting in a linear voltage output. This product offers good linearity, repeatability, stability, and high sensitivity. Customers can use standard amplifier circuits for signal amplification and compensation to achieve high-precision, stable, and reliable pressure measurements. Available in a standard DIP6 package, it is suitable for non-corrosive gas and liquid pressure detection in medical, smart home, and industrial control applications.
