Application of differencial pressure liquid transmitte in qinshan third plant nuclear island systems

Aiming at the usual trouble in the measurement about the differencial pressure level transmitter of Qinshan third plant nuclear island system,the measure principle of differencial pressure level transmitter was introduced first,and how to transferred liquid transmitter was analyzed.Then,contraposing the display signal abnormality of the differencial pressure level transmitter of Qinshan third plant nuclear island system,the different usual trouble was investigated,the reason and proper solutions of different usual trouble was discovered.The results indicate that the usual trouble about the differencial pressure level transmitter of Qinshan third plant nuclear island system is disappear when the proper solutions is executed.Now the display signal about the differencial pressure level transmitter of Qinshan third plant nuclear island system is steady.The stable working of differencial pressure level transmitter provides effective protection to safe operating of nuclear power plants.
