Product Overview
The HBP401 series is a silicon piezoresistive pressure sensor utilizing a MEMS pressure chip with a Wheatstone bridge structure. Four resistors are diffused onto a circular silicon diaphragm. When force is applied, the crystal lattice deforms, altering carrier mobility and resistivity, resulting in a linear voltage output. This sensor offers good linearity, repeatability, stability, and high sensitivity. Customers can integrate standard amplification circuits for output and temperature drift compensation to achieve high-precision, stable, and reliable pressure measurements. The product uses a standard SOP6 package for ease of use and has broad application prospects in healthcare, smart home appliances, and industrial control.
