Product Introduction

----------------------------------------------------------------------

The USM 36 ultrasonic flaw detector has developed into a classic A-class ultrasonic flaw detector in the industry, and is the most advanced product in the GEUSM series of ultrasonic flaw detectors. It is widely used for weld detection and corrosion measurement in the power and petrochemical industries; Testing and thickness measurement of castings and forgings in the automotive and metal industries; And special material inspection for the aerospace industry.

Welding seam detection in the power and petrochemical industries

The intuitive work interface and 7-inch ultra-high brightness color screen make it easier to identify defects during weld inspection:

Gates and curves are distinguished by different colors;

Warning and information are displayed in red;

A-scans can be displayed in different colors for comparison purposes;

Display all relevant defect location parameters in color, including sound path, surface distance, depth position, and leg number;

GE patented oblique beam detection span color coded display function.

Accurate thickness measurement in the automotive industry

The USM 36 ultrasonic flaw detector provides accurate thickness measurement, allowing for precise peak values to be obtained from the echo sequence even in different acoustic paths.

Corrosion measurement in the power and petrochemical industries

Corrosion measurement can be carried out using a dual crystal probe, and the USM 36 ultrasonic flaw detector provides a screen that displays both thickness values and A-scan waveforms simultaneously, ensuring the reliability of thickness measurement.

Minimum capture mode: can provide the thinnest measurement reading after continuous scanning is completed.

Automatic freezing function: It can effectively reduce the contact time between the probe and the workpiece, and can be used for surface measurement of structures and high-temperature parts.

Testing of forgings

The phantom wave detection technology of USM 36 ultrasonic flaw detector is used to detect fine grain structured materials and elongated workpieces to ensure that defect detection is not affected by phantom waves.

Testing of special materials

The powerful square wave pulse emitter is one of the optional features of the USM 36 ultrasonic flaw detector, providing excellent penetration even in harsh materials. For example, materials commonly used in the aerospace and automotive industries.

characteristic:

The USM 36 ultrasonic flaw detector has the largest A-scan screen among products of the same level: a 7-inch large screen with a resolution of 800 x480 pixels. The entire screen area can be used as an A-scan display area, allowing for clear viewing and accurate analysis of detection signals, effectively alleviating eye fatigue caused by prolonged work. The backlight adjustment function ensures that graphics are still clearly visible in bright sunlight.

Simpler and more efficient operation: The USM 36 ultrasonic flaw detector inherits the familiar knob design of previous generations of USM series products, but simplifies the function keys into six, making operation more intuitive, simple, and efficient; The detection setting is very easy, especially for technicians familiar with GE products, they can directly get started, eliminating the tedious process of reading the user manual. Its set value can also be directly transmitted through the instrument interface and maintain interface commonality with USM products in the same series.

Elastic data reporting and storage: The data report of USM 36 ultrasonic flaw detector can also be equipped with A-scan screenshot and video recording functions, and can be recorded for later analysis or to provide proof of testing. All data is stored on a replaceable SD card, and the report can be presented in JPEG and BMP formats.

Convenient data sharing: Data can not only be stored on SD memory cards or USB for backup or sharing. It is also equipped with a VGA connection socket for connecting external displays or projectors, making it convenient for viewing or teaching applications.

Can be used in harsh environments: The USM 36 ultrasonic flaw detector has sufficient protection capabilities, with a dust and water resistance rating of IP65 design. can

It can be used in environments ranging from -10 ° C to+55 ° C and can be used in deserts, ice fields, and humid tropical environments. Such a comprehensive ultrasonic flaw detector weighs only 2.2 kilograms and can work continuously for over 13 hours when fully charged.
