PRODYN’s precision D-Dot sensors measure the rate of change of an electric field, this includes free field and surface measurements. These differentiating sensors are passive devices that are lightweight and portable. Several models cover frequency ranges from near DC to >10GHz. The fast rise times acheived by these devices make them ideal for measuring transient events such as EMP or lightning.

The “AD” series models, with precise asymptotic dipole elements, are the latest and most accurate D-Dot sensors available. They exhibit less capacitance and better higher frequency characteristics compared to HSD sensors

Prodyn free field D-DOT sensors are frequently used to calibrate an electric field before exposing the EUT in a radiated susceptibility testing:
