3. § By visually inspecting an item, it is easy to understand the whole situation, and a
complex idea can be conveyed with just a single still image
§ RVI makes it possible to absorb large amounts of data quickly
Remote Visual Inspection (RVI)

4. RVI is a visual inspection, and visual defects can be measured
For sub-surface/internal defects, other Olympus products may be used, including NDT and ANI
Benefits of RVI
1. Easy to understand what is happening inside a component
2. On-site inspection is possible
3. No need to use a special wave
4. No need for a special license

5. 50% of us can identify
this
50% of us can identify
this
Probably only 10% can
gain anything from this
RVI Compared to Other Techniques

6. RVI Compared to Other Techniques
We can all draw a
conclusion from this

8. Commercial wind
turbines can be
operational for over
20 years
Frequent reasons
for wind turbine
damage include:
• Corrosion
• Moisture
• Lightning strike
• Material loss in the
machinery
Continuous
monitoring systems
are installed to
detect early
warning signs of
damage
Improving Turbine Lifetime with Gearbox Inspections

9. Common Inspection Points
Inside a wind turbine nacelle
High/mid/low and planetary stage
gears and bearings
High/Mid/Low speed gear
Planetary gear
§ To address these early warning signs and as a routine precaution, wind turbine gearboxes are regularly
inspected to avoid repairs and downtime and to ensure a long lifespan

13. Lightweight and ergonomic design
Addressing the Challenges: IPLEX® G Lite
Videoscope
§ 1.15 kg (2.5 lb)
§ Compact body fits in your palm with a hand strap
§ Carrying case easily fits in most airplane overhead bins
Case size: W 455 H 330 D 175 mm
W 18 H 13 D 7 inches

14. Rugged
Addressing the Challenges
§ IP65 rain and dust resistant
§ Tested to U.S Department of Defense
standards (MIL-STD-810G and 461G)
MIL STD Type
MIL 810G 1.2 m (4 ft) drop test
Vibration
Blowing rain
Humidity
Salt fog
Sand and dust
Icing/freezing rain
Explosive atmosphere
MIL 461G Electromagnetic interference (EMI)

15. Improved brightness
Addressing the Challenges
§ A powerful LED in the main body provides 2x the
brightness of its predecessor (IPLEX UltraLite)
§ The PulsarPic™ processor and WiDER® technology
continuously optimizes image brightness

18. Clearer images during oily inspections
Inspection Efficiency
Conventional model
Oil clearing design
Oil remains on the lens
New design remove oil
using grooves
§ New design remove oil from the surface of
the distal end
§ Spend less time cleaning, more time
inspecting

19. Inspection Efficiency
TrueFeel® electric articulation
§ The IPLEX G Lite videoscope’s ergonomic design is complemented by TrueFeel articulation,
making the joystick incredibly responsible
§ A light touch produces an immediate response and precise movement from the insertion tube
so that it is easier to maneuver the scope

20. Inspection Efficiency
Live image streaming
§ Wirelessly send live inspection images to smartphones and tablets.
§ Secure streaming with the connection channel and password
Wireless USB adaptor Dedicated iOS app:
RVI Image Share

21. Inspection Efficiency
Constant video recording
§ The IPLEX G Lite videoscope automatically records the last 30 minutes of your inspection, even
between startups and battery changes
§ This function repeats “capture new” and “delete old,” so the recording media does not become empty.

22. Inspection Efficiency
Video recording index function
§ During movie recording, it’s simple to add an index so that an inspector can find the
bookmarked location quickly
Still image capture function
§ With the push of a button, take a still image while
recording a video
§ By adding index marks, you can skip backward
and forward to the marked positions when
playing back or pausing the movie

23. Inspection Efficiency
InHelp™ inspection assist software helps you:
1. Streamline your inspection with a customizable workflow
2. Manage all the inspection media in one location
3. Quickly generate inspection reports with customizable templates
