B-DOT SENSORS

3-AXIS MAGNETIC FIELD SENSOR

DETECT LIGHTNING MAGNETIC FIELDS WITH CONFIDENCE

Lightning-radiated magnetic fields induce transient currents in wiring harness, cabling, and internal electronics of instrumentation, monitoring, and control systems. Voltages developed as a result of these induced currents can damage critical systems or prematurely stress components, leading to latent damage that manifests at later times. How can operators determine when critical systems have been exposed to potentially damaging lightning-related magnetic field transients?

B-DOT SENSOR
FEATURES

3-Axis Measurements

Accurately determine the direction and strength of the magnetic field source.

Ruggedized

Continuous deployment in harsh outdoor environments.

Signal Conditioners

Add optional analog integrators to produce sensor outputs proportional to the magnetic field strength.

High-Bandwidth

Precisely capture fast lightning-generated magnetic field impulses.

Mounting Configurations

Sensor mounting to poles, beams, or flat surfaces.

Ground-Truth Data

Capture ground-truth magnetic field waveforms for validation of threshold exceedance and inputs for electromagnetic and transient system models.

SLS’ three-axis magnetic field derivative (B-dot) sensor simultaneously detects the horizontal and vertical components of lightning-radiated magnetic fields. These compact sensors are packaged in a rugged fiberglass-reinforced plastic (FRP) housing that will withstand harsh environmental conditions, including prolonged UV exposure, corrosive environments, and vibration.

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, among other critical installations.
