Industrial Ferromagnetic Inspection Crawler: The viZaar iPIDRO
Discover how the viZaar iPIDRO ferromagnetic crawler can seamlessly integrate into your industrial inspection operations
Inspecting Metallic Surfaces Without Unnecessarily Exposing Operators
In industry, the visual inspection of tanks, pressure vessels, piping, boilers, or steel structures can quickly become complex when the areas to be inspected are hard to reach. Scaffolding, working at heights, confined space entry, and production shutdowns can increase costs and safety risks associated with maintenance operations. The viZaar iPIDRO industrial ferromagnetic inspection crawler provides a Remote Visual Inspection (RVI) solution designed for steel surfaces and other compatible ferromagnetic materials. Thanks to its magnetic adhesion system, this ferromagnetic crawler can travel on vertical and inverted surfaces while streaming Full HD images to the operator.
A Magnetic Inspection Crawler Designed for NDT
The viZaar iPIDRO combines mobility, magnetic adhesion, and high-resolution imaging in an exceptionally compact form factor.
Its key features include:
Magnetic adhesion on ferromagnetic surfaces
Vertical and inverted mobility
Footprint diameter of approximately 48 mm
Full HD camera (1920 × 1080)
145° field of view (FOV)
Motorized remote focus
Integrated LED illumination
Speed up to 3 m/min
20-meter range/tether length
Image and video recording capabilities
This configuration allows the inspector to remotely operate the crawler and acquire detailed views of areas that would otherwise require heavy access logistics.
Remote Visual Inspection of Industrial Equipment with the Ferromagnetic Crawler
The magnetic inspection crawler can be deployed across various visual testing (VT) and remote inspection applications:
Steel tanks and pressure vessels
Industrial piping systems
Boilers
Power generation equipment
Oil & Gas facilities
Chemical processing plants
Steel structures
Hard-to-reach areas
During the inspection, the operator can maneuver the crawler over the surface, identify an anomaly, stop movement, adjust focus, and capture high-resolution images or video sequences.
The system thus enables visual documentation of phenomena such as corrosion, coating degradation, mechanical damage, or surface defects.
Reducing Complex Access and Associated Risks
A primary advantage of a ferromagnetic inspection robot is minimizing—where site conditions permit—the direct exposure of personnel to hazardous or hard-to-reach areas.
Using a crawler can help reduce reliance on temporary access equipment, such as scaffolding, and limit work at height or within confined spaces.
However, it does not replace safety protocols, the expertise of certified NDT personnel, or other NDT methods. It serves as a complementary tool for visual data acquisition.
A Tool for Asset Integrity Management
For maintenance managers, the viZaar iPIDRO ferromagnetic crawler offers a more flexible approach to visual testing.
Captured images and video recordings enhance inspection reporting and assist in identifying areas requiring further non-destructive evaluation, such as Ultrasonic Testing (UT), Magnetic Particle Testing (MT), or other NDT techniques.
The underlying principle is straightforward: bring the inspection capability to the surface rather than sending the operator to the hazard area.
viZaar iPIDRO: The Ferromagnetic Inspection Crawler for Your Industrial NDT Operations
Compact, remotely operated, and engineered for ferromagnetic surfaces, the viZaar iPIDRO is an industrial crawler solution tailored for applications where accessibility is a major constraint.
For NDT professionals, maintenance teams, and asset integrity engineers, it provides a modern approach to visual inspection: magnetic adhesion, remote mobility, Full HD imaging, and reliable documentation of hard-to-reach areas.
