DESCRIPTION
Early warning is required wherever humans are likely to be directly
threatened by the presence of strong electromagnetic fields. Antenna and
radar equipment and machines which use strong electromagnetic fields to
heat, weld or bond materials are typical sources of dangerous fields.
RadMan and RadMan XT provide safe and timely warning of electro-
magnetic fields in these areas of application.
Warning and indication
A warning buzzer will produce a loud sound as soon as 50% of the
maximum permissible exposure limit is exceeded. The included earphone
is ideal for noisy environments. Four level indicator LEDs provide an
approximate indication of the measured field strength in steps of 12.5%,
25%, 50% and 100% of the radiated power density.
Matching the standard
The shaped frequency response of the field sensors mirrors a particular
standard. There’s no more need to adjust the alarm limit to the frequency
of the field source or service. Thanks to the shaping the alarm limit is
always matched – over the entire frequency range. Different versions of
RadMan and RadMan XT are available to cover the different national and
international standards.
Distance-independent operation
The fixed relationship between electric and magnetic field does not apply
in the near field of radiation. RadMan and RadMan XT have both electric
(E) and magnetic (H) field sensors – for reliable warning independent from
distance to the source.
Minimized influence of the body
Personal monito rs are mainly used “on the body”, best worn on the outside
of clothing. To minimize reflections caused by the human body, the yellow
cap of the RadMan and RadMan XT includes a specially designed RF
absorber. The absorber cap can be repositioned on the opposite side of
the housing to obtain isotropic (non- directional) response for use “off the
body”.
Data logger included in RadMan XT
RadMan XT continuously records the measured values for both the E field
and the H field and adds a time stamp to each record. The data logger is
always on and is able to store more than 1600 records. When the circular
memory is full, it simply stores the newest data in place of the oldest data.
PC Interface Kit (Option)
For downloading and analyzing
logged data from RadMan XT
