Rmic Acoustic Leak Sounding System
Introduction
The Rmic (pronounced R Mike) is a highly effective ground microphone for all
weather conditions. It consists of a lightweight portable amplifier module, as used in
the Gmic system, a set of mono headphones, and a ground microphone housed
within an acoustically shielded foot.
It is an effective electronic instrument to confirm the position of underground leaks
audibly from ground level.
Audible indications of signal strength (and consequent proximity) are provided to
enable operators to quickly and accurately confirm leak positions.
The control module is battery powered and provides up to 50 hours operational use
before a recharge is required.
Although the system is rugged and shower-proof (to IP65), it contains electronic
circuitry and should handled with care. The equipment should be kept dry and clean.
Where necessary it should be cleaned with a damp cloth; abrasive materials must
not be used.
Optional extras include standard aviation quality headphones and a hand held probe
for sounding fittings.
Note
: The headphones supplied with the Rmic cannot be interchanged. The
impedance of the headphones is matched to the Rmic control unit during
manufacture.
