Detect Lightning Magnetic Fields with Confidence

SLS offers our customers a compact, three-axis magnetic field derivative (B-dot) sensor for simultaneously detecting the horizontal and vertical components of lightning-radiated magnetic fields. These custom sensors are packaged in a rugged housing that will withstand prolonged exposure to harsh environmental conditions. Our 3-axis B-dot sensors are currently being used to detect lightning signals on NASA’s Mobile Launch Tower and inside NASA’s Orion crew capsule. The 3-axis B-dot sensor specifications are given below:
