In the process of oil and gas well,the pressure is a very important index.With the development of the oil and gas well,the precision and reliability of the pressure is demanded more strictly than ever.A kind of electric pressure gauge which is composed of vibratory sensor and single chip microcomputer is introduced.The gauge acquires data by using newly developmental vibratory sensor,moreover,the hole measuring process is controlled by single chip microcomputer which processes the data synchronously and stores them,displays and sends them to the PC to do further procession.The vibratory sensor has a very good stability,strong anti jamming ability and is easy for data transmission.This gauge has of high automobility,reliability and precision.
