Fürstenau, Eppens & Co Desconhecido
1920
- Intensimeter
Intensimeter was used to determine the acoustic radiation power of panel models in the field of aerodynamic pressure pulsations, namely in the field near a vibrating surface, allowing to establish the effect of the static charge of the panel on the power of its acoustic radiation in the vicinity of the first resonant frequencies, demonstrating that the effect decreases with increasing frequency.
The Fürstenau intensimeter was invented by Dr. Robert Fürstenau in the 1920s.
The Fürstenau intensimeter was one of the first devices to replace doctors' skin as a way to test the intensity of radiation, a method that caused serious injuries.
The Fürstenau intensimeter made it possible to measure the amount of ionized radiation using a selenium cell.
Although his invention was important, it was not fully effective and, gradually, the Fürstenau intensimeter was replaced by more accurate measuring instruments.
