APPLICATIONS
Safety in occupational environments
According to several safety regulations worker exposure cannot exceed
specified limits.
Emission from several industrial machines operating in the high frequen-
cy range could be potentially dangerous to the operator.
In the Near Field region near that kind of apparatus accurate measure-
ments of both Electric and Magnetic fields should be taken to demonstra-
te compliance to safety standards.
EHP-200, equipped with both electric and magnetic field sensors within a
small housing, is the ideal solution to perform accurate measurements
and spectrum analysis in the 9 kHz 30 MHz frequency range.
Its small size and optical output enables minimum field perturbation.
Broadcasting Surveillance
The EHP-200 is particularly useful in measuring the actual fields genera-
ted by long, medium and short wave broadcast transmitters, to ensure
safety around the sites of large antennas, to control power transmitted in
the radiation direction, to test transmitting antenna functions and identify
borders between near and far field regions.
Wave impedance
As a unique feature, the PC program calculates field wave impedance by
dividing the total value of the E-field by that of the H-field. This method is
particularly suitable for evaluating the non-linear, scattered near-field
region of large broadcast antenna systems.
Both electric and magnetic fields can be displayed on the Power density spectrum is calculated over real electric
same graph. and magnetic field measurement and therefore applicable
to both far and near field conditions.
