Magnetic field alarm indicator

摘要: A magnetic field alarm detector comprised of a plurality detectors mounted in horizontal plane for detecting respective rotational components and response generating signals proportional thereto. Each the is at predetermined angle with respect to adjacent ones detectors, thereby encompassing 360-degree view. Circuitry included rectifying summing received from an output signal. Additional circuitry provided comparing signal set-point event greater than one or both audible visual The indicator present invention particularly useful measuring high strengths preventing accidental malfunctioning sensitive medical equipment such as infusion pumps, ventilators, etc., protecting magnetically tapes, credit cards etc.
