Evaluation of EMC characteristic of Level Gauge based on fuzzy comprehensive evaluation method

In order to evaluate the electromagnetic compatibility characteristics of Level Gauge, the project of the EMC (electromagnetic compatibility) characteristics immunity test of level gauge was brought up in paper. Fuzzy comprehensive evaluation method was used to evaluate the electromagnetic compatibility characteristics of Level Gauge. The weight was determined by the method of Analytic Hierarchy Process. It could make the assignment of each factor more scientific, reasonable, and the reflection of the influence from different factors of EMC immunity to the level gauge would be better.
