Field Measurement: E-Field Sensors – D-Dot | PPM
The D-Dot E-Field Sensors from PPM Test are high-precision capacitive sensors designed to measure fast-changing electric fields. These sensors are optimized for applications involving high-voltage pulses, fast transients, and EMC testing. Operating on the D-dot principle, they measure the time derivative of the electric field, enabling excellent temporal resolution.
