Additional Transducers
1.3.3.1 Acoustic Sensor ST 034.A
The sensor incorporates an acoustic transducer (microphone) and a preamplifier.
Connect to the socket for external sensors.
1.3.3.2 SHF antenna-detector "ST034.SHF"
ST034.SHF consists of the structurally integrated log -periodic
antenna and SHF detector-amplifier.
Connect to the socket for external sensors.
1.3.3.3 Magnetic field probe "ST034.MF"
ST034.MF structurally consist of the ferrite antenna (FA) and preamplifier.
ST034.MF operates in two modes:
•
«
MAGNETOMETER
"- directly as a magnetic field intensity sensor (a
mode selector is in a position "DOT
"
). In this mode, you can measure
the intensity (induction) of the magnetic field.
•
"
GRADIOMETER
" - as a gradiometer. When using gradiometer mode field intensity difference is
measured in two points at the magnetic axe FA placed symmetrically as to the center of the FA. In
this mode an influence of remote sources of magnetic field is reduced significantly.
Connect to the socket for external sensors.
