The Multigauge 4100 and 4400 Underwater Thickness Gauges are simple, robust ultrasonic
thickness gauges designed to be mounted onto all types of work class ROV’s. There
are two models in the range, the Multigauge 4100 which has a depth rating of 1000m
and the Multigauge 4400 which has a depth rating of 4000m. Both gauges have been
designed and built to survive extremely harsh conditions that exist in the offshore
and underwater industries worldwide. The gauges use multiple echo which means measurements
can be easily taken without the need to remove coatings and the RS422 output makes
connection to most ROV’s simple.
The gauge is equipped with IPR (Intelligent Probe Recognition),which automatically
adjusts settings in the gauge for enhanced performance and AMVS (Automatic Measurement
Verification System) to ensure only true measurements are displayed, even on the
most heavily corroded metals.
Multigauge 4000 Gauge, probe, spare membranes, membrane oil, 15mm test block, membrane
key, spare 'O' rings, Molykote grease, nose cone release bar, manual, calibration
certificate, carry case, communicator software, RS422 - RS232 converter, Impulse
connector with fly lead, ROV test cable, power supply for use with test cable.
The Multigauge 4000 is supplied with Tritex Communicator software which allows datalogging
on a PC or laptop using templates. These can be setup to store data in a grid, string
or combination of both. Alternatively, the software can be used to simply display
the measurements directly from the gauge.
Sound Velocity Range:
From 1000 m/s to 8000 m/s (0.0394 in/µs to 0.3150 in/µs)
The Multigauge ROV Probe Holder has been designed to accurately present the ROV probe
onto the surface being measured, whether it is curved or flat. The ingenious design
means there are no moving parts to get clogged with silt and seaweed and yet there
is a 75° freedom of movement in all directions due to the rubber joint - there are
no axial restrictions. The Probe Holder is made from titanium for lightness and strength.
