Ultrasonic Thickness Gauge
up to 6 mm
The EM1401 UT ultrasonic thickness gauge measures thickness of steel pipes, sheet metal, rods, and other products made of steel, aluminum and other metals with an operating gap between the transducer and the metal up to 6 mm. The gap can consist of dirt, rust, salt deposits, paint, varnish, enamel, plastic or other non-conductive coating.
The EM1401 UT thickness gauge has a color display protected by impact-resistant glass.
The device uses a special data processing algorithm that provides correct thickness measurements in the presence of disturbing factors such as metal anisotropy, usage of several reflectors, exposure to external interference. In addition to the automatic thickness measurement mode, the EM1401 UT allows using manual measurement modes based on the first echo and difference between any two echoes. Manual mode is recommended for severely corroded objects.
Just bring the transducer to the surface of the object being tested
Works both on flat surfaces and on surfaces with a radius of curvature of 10 mm and more
For standard EMA transducers, the operating temperature range on the test object surface is -20…+80 °С. Special EMT14014T transducer measures thickness on objects heated up to 750 °C
The EM1401 UT allows the user to analyze A-scans, visualize B-scans (three display options), and save data conveniently on C-scans in a matrix form. If necessary, the user can work with gates, select a thickness measurement mode, signal processing parameters, etc.
The EM1401 UT can operate with:
• standard EMA transducers with a permanent magnet.
• piezoelectric transducers:
– transducer 5 MHz, aperture diameter is 10 mm,
– transducer 5 MHz, aperture diameter is 7.2 mm,
– transducer 10 MHz, aperture diameter is 5 mm.
The EM1401 UT implements a special algorithm that accounts for changes in the rate of sound propagation in metal induced by temperature.
