YW-131 Diffusion Silicon Piezoresistive Pressure Transmitter

Description

YW-131 Diffusion Silicon Piezoresistive Pressure Transmitter
Overview
YW-131 diffused silicon piezoresistive pressure transmitter is a high-performance pressure transmitter designed for use in harsh environments. Its shape is a compact integrated all-stainless steel structure, which is easy to install, has the advantages of good vibration and shock resistance, high accuracy, good stability, etc., and is widely used in petroleum, chemical, metallurgy, water conservancy, electricity, food, medicine, etc. Industry pressure, level measurement and process control.
working principle
Utilizing the piezoresistive effect of single crystal silicon, using single crystal silicon as the substrate, and using specific micro-orientation to form an elastic element using advanced micromachining technology, and forming four equivalent strain resistors using integrated circuit technology at its appropriate positions Stein bridge, applying a constant voltage (current) to the bridge. When a pressure (differential pressure) is applied to the elastic element, it causes it to output a voltage signal proportional to the applied pressure. The voltage signal is passed through the electronic circuit. Amplify and convert to a 3-wire 0-5V output.
