Abstract:Induction type magnetic sensor is being used effectively in electromagnetic prospecting and earthquake prediction, which is very important for the investigation of earthquake precursors. In this paper, a new means of frequency compensation is discussed for inductive magnetic sensor in the electromagnetic disturbance instrument. This paper deals with its equivalent circuit, compensating circuit, main technical specifications and performance test method. This sensor can be used to detect a natural electromagnetic disturbance with the variation ranging from 0.1 to 10 Hz electromagnetic disturbance.
