Product Overview
The HBP411 product series are piezoresistive MEMS pressure sensors 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. These sensors offer good linearity, repeatability, stability, and high sensitivity. They are available in a standard DIP6 package and are suitable for detecting pressure in non-corrosive gases and liquids. Customers can utilize standard amplification circuits like instrumentation amplifiers for output and temperature drift adjustment and compensation to achieve high-precision, stable, and reliable pressure measurements. The product has broad application prospects in healthcare, smart home appliances, and industrial control.
