Operation status identification and evaluation method of vibrating wire monitoring instrument

The main content of this paper is how to diagnose and identify the health status of the vibrating wire monitoring instrument in the operating period. The methods and criteria of basic information evaluation, historical values evaluation and field detection and evaluation are given respectively. In which, the evaluation methods and evaluation criteria of starting of oscillation of vibrating wire are innovatively put forward. The paper presents treatment suggestion and anomaly causation analysis of instrument evaluated as abnormal, and analyzes the reason of modulus deviation between manual data and automated data.
