Special probe “2x2”
For crack depth meters
The Special probe “2×2” is engineered to operate on surfaces with a small distance between cracks ranging from 0.5 to 20 mm, making it ideal for precise crack depth measurements with ET-28 crack depth meter.
With four electrodes arranged in two rows, this sensor offers enhanced capabilities for versatile crack detection.
Application
Measuring the depth of cracks in various metals and alloys, including stainless steel and duraluminum. Utilizing AC electro potential measuring, the meter provides rapid and precise depth assessments compared to traditional methods.
Typical control objects
- Shafts, rolls, rolling mills, and components of constructions, machines, and mechanisms.
- Pipes, tubes, and oil-and-gas pipelines.
- Pressure vessels.
- Devices in the energy industry.
Operational advantages
- Control of ferromagnetic and non-ferromagnetic materials: the probe is suitable for monitoring a wide range of materials, including stainless steel, aluminum alloys, and more.
- With a measuring range from 0.5 to 20 mm, the “2×2” sensor accommodates various crack depths.
- Designed to work on surfaces with closely spaced cracks, the sensor enables efficient measurements in grid-like patterns.
- The “2×2” probe allows measurements in hard-to-reach places, ensuring comprehensive crack detection.
- Equipped with spring-loaded contact electrodes, the probe facilitates measurements on curved surfaces, enhancing flexibility and accuracy.
- The measurement results remain consistent regardless of the material’s electromagnetic properties, ensuring reliable performance.
Attention
If purchasing only the "2x2" Special probe, the Crack Depth Meter ET-28 requires retrofitting and alignment.
Exploitation
Prior to each usage for measuring crack depths, it is imperative to verify the device’s operation using a control sample.
Stages of crack depth measuring
- Setting of the “0” – measuring on flawless location of the object.
- Measuring of crack depth – contact electrodes are located on the opposite sides of the crack, measurement result in mm is shown on the screen.
Requirements for control objects:
- Surface roughness – below or equal to 40 Rz (10 Ra).
- Stable electric contact with the probe electrodes.
Delivery set
Special probe «3+1» (with external electrode) — 1 piece.
