Abstract

The invention discloses a weak magnetic flow detector. The detector comprises a flux induction module, a first amplification module, a second amplification module, a controller and a network module, wherein the flux induction module is arranged in a measured magnetic flow environment, and used for converting a magnetic intensity signal into an electric intensity signal; the first amplification module is connected with the flux induction module, and used for stabilizing the voltage value of the electric intensity signal in a fixed amplitude; the second amplification module is connected with the first amplification module, and used for carrying out impedance matching on the electric intensity signal after amplitude is stabilized; the controller is respectively connected with the first amplification module, the second amplification module and the network module; and the controller is used for controlling the voltage stabilizing amplitude of the first amplification module, receiving the electric intensity signal which is subjected to impedance matching by the second amplification module, and transmitting the electric intensity signal to the network module. The method has the advantages of strong interference resistance, long-distance transmission availability and the like since an automatic gain amplifier is introduced to stabilize output signals.

Description

technical field [0001] The invention relates to a weak magnetic flow monitor. Background technique [0002] Magnetic flow measurement works on the principle of electromagnetic induction, transforming magnetism into electricity, and measuring electricity to measure magnetism. [0003] The existing magnetic flow measurement equipment has the characteristics of low stability and is easily disturbed by noise. The data can only be stored locally and cannot be transmitted. [0004] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0005] The purpose of the present invention is to provide a weak magnetic flow monitor, so as to overcome the disadvantages that the existing magnetic flow measurem...
