It is best to choose the shortest length that will suit your inspection needs for a number of reasons. First, the shorter the insertion tube, the greater the degree of articulation in the bending section. Second, shorter insertion tubes are easier to handle and work with than longer insertion tubes. Finally, shorter insertion tubes are less expensive to buy and repair.
No. Some companies do offer joystick controlled videoscopes with significantly longer insertion tubes, but they can do this because their joystick articulation control is motor driven. Articulation with the VJ-3 is direct mechanical, as described above. The advantage to other systems is that their motors can be geared to exert much more force on the control cables, which is necessary when the length of the insertion tube increases. The advantage to the VJ-3 method is that the articulation control is much more sensitive to the user’s inputs, the bending section stays in position without locking, and it is much less expensive to purchase and repair.
The camera, bending section and insertion tube are liquid-proof. The handheld portion of the unit is not liquid-proof. During an inspection, the insertion tube will often come into contact with oil, lubricants, diesel, kerosene, jet fuel, etc. This is not a problem. After such use, the insertion tube should be wiped off with a dry rag and allowed to air dry. Care should be taken when drying the bending section, and it should be “dabbed” dry instead of “rubbed” dry. The only common liquid that should be avoided, if possible, is gasoline, because gasoline is more corrosive than other fuels or lubricants. Incidental contact with gasoline will not damage the scope, but prolonged contact or soaking in gasoline may damage the scope.
No. Some of the very high end videoscopes on the market have what is referred to as a “measurement function.” Through a variety of methods, these systems can tell the operator the size of a defect such as length of a crack or the area of a scorch mark. In the development of the VJ-3 it was decided not to add a measurement function for two reasons. First, it adds a tremendous amount of cost and complexity to the product. Second, for most inspection scenarios across most industries, defect measurement is simply not needed.
There are a number of key differences between these low-end products and the VJ-3.
Articulation: Low-end videoscopes do not articulate (meaning the camera section cannot be controlled and pointed in other directions). A scope without articulation is like a car without a steering wheel. It’s great as long as you only need to go straight. These low cost scopes may work well for certain types of inspections, such as small-bore pipe inspections, where there would be no room to move an articulating tip. In the vast majority of cases, the usefulness comes from being able to place the insertion tube into an inspection area and then move the camera around to see what you need to see. The ability to articulate the camera is the most critical feature missing from low-end scopes, and the value of articulation cannot be overstated.
Image or Video Capture: If a technician ever wants to archive pictures of an inspection, get a second opinion, compare the same part from one date to the next, or show a customer the results of an inspection, you must have image and video capture. Most low-end scopes do not have an image or video capture. Some of these products may have a video output through which you could record an inspection on a computer, but this adds complexity and cost while reducing portability.
Image Quality: The VJ-3 uses a high end camera and lens system to deliver 450,000 pixel resolution and a focal range of 7mm to infinity. Check the resolution and focal range of these systems and you will see that they are usually inferior to the VJ-3.
Insertion Tube Material: VJ-3’s insertion tube is pliable enough to snake through bends, elbows and curves. Some of the low-end product insertion tubes are too rigid to do this. Some are made out of metal goose neck material, much like electric wire conduit. This type of insertion tube material, combined with a lack of articulation, significantly reduces the type of inspection scenarios in which it can be used..
