Mikrosize Ultrasonic Flaw Detectors – Advanced Portable NDT Solutions for Industrial Integrity
In modern industrial environments, the reliability of materials and components is non‑negotiable. Whether in aerospace, petrochemical, power generation, or heavy manufacturing, undetected internal defects such as cracks, porosity, inclusions, or delaminations can lead to catastrophic failures, costly downtime, and safety risks. Ultrasonic flaw detection, as a cornerstone of non‑destructive testing (NDT), provides a proven, accurate, and repeatable method for evaluating material integrity without causing any damage.
Mikrosize – a globally trusted supplier of precision measuring and testing instruments – offers a comprehensive portfolio of portable ultrasonic flaw detectors designed to meet the most demanding inspection requirements. Our instruments combine advanced hardware architecture, intelligent software, and rugged portability, empowering inspection professionals with the tools they need to detect, locate, and characterise defects with confidence.
Operating Principle – Precision Through Sound
Ultrasonic flaw detectors operate on the pulse‑echo principle. A transducer emits high‑frequency sound waves into the test material. When these waves encounter a discontinuity – such as a crack, void, or inclusion – part of the energy is reflected back to the transducer. The instrument analyses the time‑of‑flight and amplitude of the returning echoes, enabling precise calculation of defect depth, position, and relative size. Additional modes, including through‑transmission and tandem testing, are available for specialised applications.
Mikrosize detectors leverage high‑speed digital signal processing, with hardware sampling rates up to 100 MSPS and equivalent rates reaching 400 MSPS, ensuring faithful waveform reproduction and reliable defect detection even in challenging conditions.
Key Features – Engineered for Performance and Usability
Mikrosize ultrasonic flaw detectors are built to excel in both laboratory and field environments. Common advanced features across our models include:
- High‑Resolution Display – Bright 5.0‑inch or 5.7‑inch IPS LCD screens with wide viewing angles, 60 Hz fast refresh rates, and user‑friendly graphical interfaces. Full‑screen touch operation, gesture control, and virtual keyboards are supported on select models.
- Flexible Probe Support – Compatible with single‑element, dual‑element (TR), angle beam, through‑transmission, and climbing probes, covering frequencies from 0.1 MHz to 20 MHz.
- Comprehensive Curves – Built‑in DAC (Distance Amplitude Correction) and AVG/DGS (Amplitude‑Velocity‑Gain / Distance‑Gain‑Size) curve generation with up to 16 reference points, automatic gain floating, and real‑time evaluation.
- Advanced Gate Functions – Dual independent gates (A and B) with positive/negative alarm logic, lost‑wave/incoming‑wave alert, and gate expansion for detailed signal analysis.
- Measurement and Analysis – Real‑time display of sound path, surface distance, depth, amplitude, and equivalent reflector size (ERS). Peak memory, envelope, echo freeze, and automatic peak search simplify defect characterisation.
- Data Management – Internal storage for up to 500 channel files and 1,000 report files (or more depending on model), plus SD card expansion. Export inspection reports as PDF files directly to USB drives for easy archiving and printing.
- Connectivity and Reporting – USB and Type‑C interfaces support flash drive mode (U‑DISK) and PC communication (U‑BRIDGE). The instrument generates customisable PDF inspection reports, including company logos, test parameters, and defect data.
- Power and Portability – Built‑in high‑capacity lithium batteries (7.4 V, 8000 mAh) provide up to 12 hours of continuous operation. PD65W fast charging via Type‑C ensures minimal downtime. Compact dimensions (approx. 183 mm × 113 mm × 45 mm) and lightweight design (approx. 700 g) enable one‑handed operation.
- Video Recording and Screenshot – Record inspection sequences (up to 5 minutes per file internally, or unlimited via external USB) and capture screenshots in BMP format for later review, training, or documentation.
- Weld and AWS Functions – Dedicated weld graphics display the probe position relative to the weld joint, assisting in defect localisation. The AWS D1.1/D1.5 rating function automatically classifies indications into acceptance classes (A‑B‑C‑D) based on the standard.
- Environmental Durability – Operating temperature range from ‑10 °C to 55 °C, with robust housing and protective rubber cover for resistance to moisture, dust, and moderate impact.
