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 on a circular silicon diaphragm. When force is applied, the crystal lattice deforms, altering carrier mobility and resistivity, resulting in a linear voltage output. This product offers good linearity, repeatability, stability, and high sensitivity. Customers can select standard amplification circuits like instrumentation amplifiers for output and temperature drift adjustment and compensation, achieving high-precision, stable, and reliable pressure measurements. The sensor is available in a standard SOP6 package for ease of use and has broad application prospects in healthcare, smart home appliances, and industrial control.
