UMX-2 Ultrasonic Thickness Gauge

The UMX-2 Underwater gauge is the latest addition to Qualitest product range. Fully equipped with DSP platform using FPGA technology, it's extremely versatile for all those offshore inspections. The enclosure is extremely durable, with a maximum depth rating of 1000ft (300m), and offers the use of both Dual & Single Membrane transducers to accommodate as per application requirements. The features include: auto probe zero, auto probe recognition, and multiple measurement mode options. Dual Element modes (corrosion inspections) include: Pulse-Echo (pits & flaws), Echo-Echo (thru-paint) & Pulse-Echo w/coating (combo). Our Single Membrane probe option uses a Triple-Echo (TCG) mode for coated and uncoated general applications. While not suitable for blind surface corrosion inspections, this option offers good linearity for general purpose applications.

The calibration section contains 8 common pre-programmed material types and 1 custom user programmable option. UMX-2 stores up to 5,000 readings in a variety of configurations. The file structure options include: sequential with auto identifier and alpha numeric grid formats. Every measurement stored also saves a copy of the UMX-2 current settings, along with an A-Scan waveform graphic.

 

Specifications

UMX-2 is an underwater ultrasonic thickness gauge that measures with extreme versatility. It has the ability to simultaneously measure coatings and material thicknesses while maintaining the ability to locate pits, flaws and defects in the material. It can also use a combination of dual and single element transducers, depending on the application requirements. Based on the same operating principles as SONAR, the UMX-2 is capable of measuring the thickness of various materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters. The principle advantage of ultrasonic measurement over traditional methods is that ultrasonic measurements can be performed with access to only one side of the material being measured.

The UMX-2come as a complete kit, ready to use, and is backed by 3 year limited warranty.

Applications: Coating and Thickness measurement using FPGA technology.

Features: Measurement modes: Dual Element - Pulse-Echo, Pulse-Echo w/Coating, Echo-Echo. Single Element - Triple-Echo (TCG). Automatic: probe zero and probe recognition.
Data storage formats: Alpha numeric grid and sequential w/auto identifier.
