摘要： An automatic salt-in-crude analysis system can include an electromagnetic circuit having a magnetic element with a first side and a second side separated by an air gap, a first winding wound around the first side, a voltage source connected to the first winding to apply a first voltage across the first winding, a second winding wound around the second side, and a voltage detector to detect a second voltage across the second winding, the second voltage induced in the second winding by the first voltage. While crude oil is in the air gap, a PLC can compare the second voltage and the first voltage, determine whether an amount of salt in the crude is greater than a threshold amount of salt by comparing the second voltage and the first voltage; and diluting crude oil in the oil tank if the amount of salt is above the threshold amount.
