Introduction
The diffused silicon pressure sensor is a piezoresistive pressure measurement device that utilizes the piezoresistive effect of monocrystalline silicon. Through diffusion technology, a Wheatstone bridge is formed on a silicon diaphragm, converting pressure-induced deformation into electrical signals. With high sensitivity, high accuracy, compact size, and low cost, it is currently one of the most widely used pressure sensors in industrial automation. This article covers its working principle, key features, advantages, disadvantages, and applications.
