Find the Ultrasonic Flaw Detector , Portable Flaw Detector and Digital LeebHardness Tester

Of all the applications of industrial ultrasonic testing, flaw detection is the oldest and most commonly used technique. Generally, sound waves of high frequency are reflected from flaws and generate clear echo patterns.

Portable flaw detector record and display these echo patterns. Ultrasonic testing is a safe testing method that is widely used in various service industries and production process, particularly in applications where welds and structural metals are used.

Sound waves are mechanical vibrations that pass through a medium such as liquid, solid or gas. These waves pass through a medium at a particular velocity in an expected direction. When these waves bump into a boundary having a different medium, they are transmitted back. This is the principle behind ultrasonic flaw detection.

Most Ultrasonic flaw detector use frequencies between 500 KHz and 10 MHz per second. At frequencies in the megahertz range, sound energy travels easily via most common materials and liquids, but does not pass efficiently via air or similar gasses. Also, sound waves of different types travel at different rate of velocities.

Additionally, wavelength refers to the distance between two subsequent points in the wave cycle as it passes via a medium. It is related to velocity and frequency. In ultrasonic flaw detector and ultrasonic thickness gaging, the minimum limit of detection is one-half wavelength and the minimum measurable thickness is one wavelength, respectively.

Modern Ultrasonic Flaw Detectors such as TFD900 and TFD800 are small, portable, microprocessor-based instruments suitable for both shop and field use. They generate and display an ultrasonic waveform that is interpreted by a trained operator, often with the aid of analysis software, to locate and categorize flaws in test pieces. They will typically include an ultrasonic pulser/receiver, hardware and software for signal capture and analysis, a waveform display, and a data logging module.While some analog-based flaw detectors are still manufactured, most contemporary instruments use digital signal processing for improved stability and precision.

TMTECK offers a variety of devices for enhanced flaw detector inspection.  These portable ultrasonic flaw detectorsare designed for excellent inspection performance and usability.  Our full range of portable ultrasonic flaw detectors provide outstanding capabilities for locating subsurface defects.

TMTECK offers digital Leeb hardness tester that work on direct impression methods (similar to conventional machines), rebound method (measured in LEEB value) and UCI method. Measured hardness number can be easily converted into any other scale like Rockwell, Superficial Rockwell, Brinell or Vickers.

Direct impression method has various probes for different loads and controlled with the load cell mechanism. These lightweight testers can be carried to any site with ease. They are equipped with an LCD operating console, user friendly interface with easy test settings and generate clear results, real time statistics and graphs.

These testers are operative up to 360° degrees of positioning, even upside down. In compliance with ASTM E110 and ISO 50157 hardness standards, it can do hardness testing on almost all metals: chromed surfaces, nitrided surfaces, aluminum, brass, copper, bronze, metal wire, ceramic items, glass materials, hard/soft steel and hard/soft plastic.
