DETECT DAMAGE WITHOUT ENTERING THE SHAFT

How the D140 rugged tablet makes camera-based infrastructure inspections safer and more efficient

 

How can underground pipelines, shafts and utility infrastructure be inspected reliably without unnecessarily sending personnel into hard-to-reach areas?

A recent Winmate success story shows how the rugged 14-inch D140 tablet becomes the central mobile display and control unit of a camera-based inspection system – and why its combination of a large display, rugged design and connectivity is crucial for this type of application.

Inspection from a safe distance

When inspecting underground infrastructure, cameras are guided through pipelines, shafts and other hard-to-reach areas. The D140 is connected directly to the inspection system and displays the transmitted images and video in real time on its 14-inch Full HD screen.

This allows personnel to assess the condition of the infrastructure directly on site without having to enter the area being inspected. Damage, blockages and other anomalies can be identified and documented immediately.

Built for demanding field conditions

Infrastructure inspections routinely involve moisture, dirt, changing temperatures and mobile field work. The D140 is IP65-rated and designed for ruggedness in accordance with MIL-STD-810G.

It also offers versatile interfaces for connecting cameras and other peripherals, along with a power supply designed for mobile field use.

It was developed specifically for demanding working environments and supports you where conventional devices reach their limits. This gives you the confidence that your device will keep working wherever you and your team need it.

“Rugged” and “Outdoor”

… what these claims are really worth becomes clear in day-to-day use. That is why TL and Winmate follow the principle that, with these devices, the mechanical design must be beyond doubt:

• IP65 protection that goes beyond the data sheet: interfaces are located behind solid, practical protective covers. Dust, dirt, water? Kept out.
• Resistance to shock, vibration and drops in accordance with military standard MIL‑STD‑810G.
• Protective rubber bumpers around the tablet, especially at the corners, help absorb impacts and drops.
• At 2,400 grams (this is no iPad!), its weight makes a clear statement about the exceptionally rugged construction made from a magnesium alloy.

An anti-glare treatment on the touch surface and optical bonding – permanently bonding the LCD and touch layer with a transparent adhesive material – significantly reduce reflections and ensure excellent readability even in direct sunlight.

The right touch mode for every application ensures optimum usability in all conditions:

• “Hand/Rain” for normal operation or wet conditions
• “Glove” for operation while wearing gloves
• “Stylus” for pen input

More than a specialised inspection device

This application is a good example of where the strengths of the D140 lie: wherever a large display, rugged construction and flexible connectivity are required in a mobile system.

This makes the tablet suitable not only for infrastructure inspections, but also for a wide range of applications in industry, service, maintenance and field operations.
