Fluxgate Magnetometers

Applied Physics Systems provides high performance analog and digital 3-axis fluxgate magnetometers designed for oil and gas exploration in challenging environments. We also offer laboratory magnetometers. Our analog and digital magnetometers are used for directional accuracy in fluxgate compass systems, magnetic fuses, magnetic anomaly detection, to measure the Earth’s magnetic fields and very small magnetic signatures, to measure magnetic fields generated by power lines as well as many other applications. Our magnetometers feature rugged construction, compact size, low noise, a high speed interface, low temperature coefficient and two communication protocols.
