Ultrasonic flaw detector UDS2M-35 is designed for detection, measurement of location coordinates, evaluation of parameters by amplitude of reflected signals and registration of defects in rails of railway track (secondary inspection), welded joints made by electro-contact and aluminum-thermite (ALTS) welding, as well as for pre-welding inspection of end sections of new and old rails before their welding at rail-welding plants or on the track. Rails of P43, P50, P65, P75, UIC60 and S49 types are subject to inspection.
The flaw detector is a portable device and is designed for manual inspection. The flaw detector realizes echo-method (EM), shadow method (TM), mirror-shadow method (STM) and mirror method (SM) of ultrasonic inspection at combined, separate and separate-separate-separate schemes of inclusion of manual piezoelectric transducers (PEP) at contact method of input of ultrasonic vibrations (UZK). The number of manual control channels is 2.

The main advantages of UDS2-PDM35:

• High fidelity of inspection due to high-resolution acoustic path.
• 100% documentation of the control process.
• Gain control with AGC and HF functions.
• Two independent measuring strobes with Automatic Tracking System (ATS) and color indication.
• Intuitive menu with logical grouping of settings and two modes – “Operator” and “Methodist”.
• Ability to create databases and monitor the technical condition of objects.
• Supports repurposing for inspection of other products.
• USB port for connecting external devices (flash drive).
• New color display with high resolution and excellent contrast in all lighting conditions.
• Coordinate device (handheld scanner) for carrying out and logging the analysis of defects in three projections, with the possibility of automatic measurement of dimensions.
• Built-in GNSS receiver (GLONASS, GPS) for positioning.
• Use of modern element base and Windows CE operating system.
• Wireless data transfer to the Diagnostic Center.
• Supports Bluetooth wireless headphones.
• Automatic tracking of acoustic contact.
• Ability to select interface language and control protocols.
• Specially designed ultrasonic transducers with temperature stable and wear resistant compounds.
