The DEU300 EMA (Electromagnetic Acoustic) thickness gauge provides a non-contact ultrasonic thickness measurement tool for various metallic materials such as steel, stainless steel, aluminum, copper, titanium commonly used in manufacturing, petrochemical, power generation and other industries. The device requires minimum surface preparation for thickness measurement because the EMA transducer has higher tolerance to surface roughness, paint, coating, scale, etc. No need for ultrasonic couplant is another practical feature particularly useful when measuring thickness at high temperature.
DEU300 is a handy and powerful tool for various applications in harsh environment thanks to the compact design, A-/B-scan display, intuitive operation and data management interface.
Key Product Features
● No need for surface polishing,penetration of anti-corrosion coating and rust, and no need couplant.
● Thickness measurement can penetrate surface corosion, paint, corroion protection and other coatings up to 4mm.The thickness value of metal objects displayed by the instrument does not need to consider the calculation of coating thickness.
● The normal temperature pulse probe replaces the powerful permanent magnet probe. Completely solves the problem of excessive suction and difficulty in separation of the EMAT probe, making manual inspection easier and safer.
● High temp probe(optional) could inspect high temp workpiece up to 800°C
● With the function of temperature compensation, the actual temperature range of high-temperature components can be input to automatically compensate the change of sound velocity, making the thickness measurement more accurate.
● Measurement non-verticality (sensor/probe perendicular to the object being measured):±25° ,which requires less perpendicularity after the probe is placed.
● It has the function of displaying, storing and querying thicknes measurment results in the form of A-scan and (time-based) B-scan images,making it convenient for users to set measurement parameters such as gates, thickness measurement modes, and signal processing.
● Using expert intelligent algorithm,tere are three thickness measurement modes: automatic mode. single gate manual mode (single peak value method),double gate manual mode(peak value method).It greatly reduces the influence of human factors and simplifies the operation steps.
● Built-in database of basic material s-wave sound velocity, and can customize s-wave sound velocity value.
● It can store 50,000 thickness values and 4,000 A-scan or B-scan data.
● The back is integrated with bright LED light, which is convenient for on-site lighting.
● A wrist band is integrated on the back for easy one-handed operation.
● AC-DC hybrid power supply, built-in rechargeable lithium battery can work continuously ≥9 hours.
● Measurement data can be transferred to PC via USB for analysis and management.
● Fully sealed IP66 dustproof and waterproof design, silicone sheath anti-drop and anti-vibration design,better suited for harsh working conditions.
