Geometrics G-828 MFAM Caesium “Cs” Magnetometer (UAV Suitable)

The Geometrics LCS050G is a laser pumped cesium magnetometer module that measures the total magnetic field strength, with a digital interface for easy integration with modular sensing platforms. The module features two sensors that can be used independently or as an intrinsic gradiometer. The sensors can also be arranged to compensate heading error or eliminate dead zone.

Features

  • Reconfigurable dual-sensor module for:
    • Gradiometry
    • Intrinsic heading error compensation
    • Dead-zone free operation mode
  • Small size
    • 15 cm3 sensor
    • 200 cm3 electronics volume
  • High performance
    • 1 pT/√Hz noise typical
    • 1 kSps sample rate
  • Low power operation
    • 5 W power consumption
  • Dead Zone
    • Polar, ± 30°
  • Modular architecture for versatile system integration

Applications

  • Autonomous Geophysical Surveys
  • Non-destructive Evaluation
  • Magnetocardiography
  • Structural Health Monitoring
