Pressure gauge circuit with magnetic components

Published:2012/11/20 20:30:00 Author:Ecco | Keyword: Pressure gauge, magnetic components | From:SeekIC

The circuit uses magnetic components FP210P250, and they form a bridge circuit with two 1kΩ resistors and connected to the input terminal of the operational amplifier. Bridge voltage is stablized by regulator in order to make it independent from supply voltage fluctuations. It uses the distance between feedback resistors R1 and small iron piece magnetic components to realize stroke control the size of the output current.
