BROADBAND H-FIELD SENSORS

Broadband & Specialized Induction Coil Magnetic Sensors

Advanced Geophysical Operations and Services Inc. (AGCOS) manufactures several low-noise induction coil magnetic sensors that ensure wide frequency band coverage from 50,000kHz to 0.00001Hz – AMS-15, AMS-27, AMS-37 & AMS-47. All sensors are waterproof and distinguished by high sensitivity and extremely low-noise which allows to acquire reliable data even in frequency bands with very weak natural signal (3000 – 700Hz, 10 – 0.1Hz). Furthermore, additional application of precision field tripods for induction coil installation on any terrain or soil conditions allows to conduct measurements in environmentally sensitive areas and increase productivity since digging holes for the sensors in the ground is not required.

Note: Multifunction EM receivers Gepard-4 and Gepard-8 have flexible channel configuration which allows to simultaneously record long period data with 3-axis fluxgate sensors as well. Please inquire for details.
