Sensor development and application on the oil-gas pipeline magnetic flux leakage detection

The current development of oil-gas pipeline magnetic flux leakage (MFL) testing sensor, this paper discussed working principle and application of the coil sensor and the Hall element sensor. The two types of sensors in practical applications were analyzed for their characteristics. The article evaluates the sensor application and development situation and proposes for MFL testing sensor development direction.
