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 electro­magnetic 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 monitors 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.

APPLICATIONS

Monitoring RF signals (occupational limits)

Mobile, telecom, broadcast and industrial applications are covered by
the standard version of RadMan and RadMan XT (with data logger). The
E field and H field sensors are shaped to match the higher level of two­tier standards, i.e. the “Controlled”, “Occupational” or “RF Worker” limits.

Monitoring pulsed radar signals

The “Fast Response” versions of RadMan and RadMan XT are

designed to detect the peaks of sharp and narrow radar pulses. The
ICNIRP standard, for example, requires peak detection when the ratio of
peak to average power is greater than 30 dB. Peak detection is obtained
by reducing the 1 second integration time for E-fields down to 30
milliseconds for all “Fast” models.

Monitoring workplaces

Fixed on a non-conductive tripod (optional accessory) the RadMan can
be used for workplace radiation monitoring. This application is ideal for
areas to be monitored occasionally. For permanent surveillance Narda
offers the wall mountable Smarts IITM.

Searching for leaks

As a locating unit all RadMan and RadMan XT versions can be used to
locate leaks on waveguides and coaxial screw connectors (picture on
the right). A non-conductive extension with handle is available as an
optional accessory.

a The percent of standard ratings refer to equivalent power density
b The alarm threshold is set to 50% of Standard ±1 dB at the calibration frequency
c This value is only significant for data logging and online measurements
d Uncertainty due to varying polarization (verified by type approval test). Ellipse ratio included
e Each record includes the maximum, minimum and average values for both the E field and the H field
f The logging interval can be selected via the ESM-TS software (optional)
g The specified frequency response can be exceeded in the range 6.2 GHz to 8.8 GHz due to resonances in the H field sensor.
No underestimation of the measured field will result from this in any case. This means that an alarm may occur at field strengths that are below the limit value.
