 ai400-TX
transmitter injects active signals by direct connection,
induced with clamp or with a built-in antenna:
- In places where it is possible to make a direct
connection, ai200 underground pipe and cable locator
signals are injected with alligator clamps: de-energized
electric cables, telephone cables, water and gas
metallic pipes, etc.
- If it is possible to access the cable but is energized,
signals may be induced with an injection clamp:
energized MV and LV cables, telephone cables, etc.
- If the cable can not be reached or its position
is unknown, induction can be made from the earth
surface using a built-in antenna on ai200: electricity,
telephone, gas and water utilities cable and pipe
avoidance before digging, etc.
Injects polarized frequencies for determining
current signal’s direction.
Injects 300Vpp signals for sheath fault location.
Injected power level on ai400 underground pipe
and cable locator is selectable up to 10W.
Measures loop impedance, making it possible to
choose the best working frequency on each case.

 ai400-RX
underground pipe and cable locator receiver detects
4 active signals (sent by the transmitter) and 2
passive 50/60Hz and radio signals (radiated by utility
networks).
Built-in antenna configuration on ai200
underground pipe and cable locator automatically
calculates the target position with a digitally
processed algorithm.
A large size LCD screen shows
two arrows that help users pinpoint underground
pipe and cables in an easy and intuitively way.
Measures pipe’s and cable’s depth by
pushing a simple button.
With A frame sensor detects and locates sheath
faults on electric distribution cables.
As an optional feature ai200 can also positively
identify (discriminate) electric and telephone
cables using different types of sensors, depending
on cable’s accessibility (trenches, manholes,
transformer substations, etc.).
