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.
