The water moisten system of examined surfaces
the best of all!
The ultrasonic examination require the effective couplant medium to achieve
good contact of probe to tested surface. The grease, oil, pastes
(wallpaper paste, starch) are traditionally used as couplant medium as well
as offered by various companies - often expensive.
Stickiness of applied liquids enables keeping their film on different oriented
in space surfaces (e.g. on the wall, ceiling etc.). These couplants are good
in cases when the probe is not moved e.g. thickness measurements.
But for weld testing in which the cue of examination is to move the probe
these couplants don't give the good contact, because probe movements wipe out
the liquid and the probe looses the contact to tested surface.
The offered water dampening system of tested surfaces gives the good contact in
every condition (Patent PL no. 72214/71). The water with detergents to get a
good conatct is being passed to the probe. The probes has capillar cracks for
spreading the water, which make the water film under the probe and can keep
this film in different positions e.g. on the walls, ceilings etc.
Cables and Cable Adapters
The lemo connectors (small type) are used in CUD to connect the probes,
which are usually equipped with 1m cable length. To connect other probes
to CUD we propose the adapters with freely combined connectors e.g.
LEMO<->BNC, LEMO (female type)<-> LEMO (male type), etc.
The adapters can work as extension cords. The length of cables may be ordered
practically without limitation (but the attenuation should be taken into
For probes manufactures by other companies without resonance circuits we
can make such circuits to the ordered cables or adapters.
The flaw detectors are supplied with aluminum protective case for keeping unit
with its equipment - dampening system, probes, power supply, CD-rom with
software, manual, straps for mounting the unit.
