Test level
*Note: U
is the mains alternating voltage before applying the test levels.
T
Note 1: The higher frequency range applies at 80 MHz and 800 MHz.
Note 2: These guidelines are probably not realizable in all cases. The distribution
and spread of electromagnetic quantities differ depending on the absorption and
reflection of buildings, objects, and people.
a
The field strength of stationary transmitters, such as base stations of wireless
phones and cell phones, ham radio operators, AM and FM radio and TV stations
theoretically cannot always be determined in advance. A study of the installation
site should be considered to determine the electromagnetic environment concern-
ing the stationary transmitter. If the field strength measured at the usage site of
the device Aquilex® Fluid Control System exceeds the compliance levels listed
above, the device Aquilex® Fluid Control System should be monitored for proper
function. If unusual performance characteristics are observed, additional measures
may be required such as changing orientation or the location of the device
Aquilex® Fluid Control System .
b
The field strength should be less than 3 V/m for the frequency range of 150 kHz
to 80 MHz.

the applicable formula. Re-
commended safety distances:
d = 1.2√P for 150 kHz to
80 MHz
d = 1.2√P for 80 MHz to
800 MHz
d = 2.3√P for 800 MHz to
2.5 GHz
With P as the rated output of
the transmitter in watts [W]
according to the information
provided by the manufacturer
of the transmitter and d as re-
commended safety distance in
meters [m].
The field strength of station-
ary transmitters for all fre-
