Abstract : The patent describes a magnetic fluxmeter having one or more signal processing channels, each of which incorporate an electrical loop magnetic flux sensing transducer, a high fidelity nanovoltmeter type preamplifier, an active integrator, a discharge circuit for changing the voltage integration range and, thus, the operational range center of said active integrator, and a scale change for causing a digital voltmeter to indicate the output signal from said active integrator on a scale that is sufficiently proportional thereto to substantially center it thereon, so as to thereby facilitate the accurate reading thereof. To monitor large geographical areas, a plurality of said signal processing channels may be employed and scanned, so that each of the outputs thereof will be timely indicated and/or recorded by a suitable readout.
