EM1401 Thickness Gauge

Is designed for thickness measurements of steel pipes, sheet metal, rods and other products made from steel, aluminum and other metals


The EM1401 EMA 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 allows measurements without usage of couplant and without surface preparation.

A special high-temperature transducer allows inspection of hot objects heated up to 750 °C.

The EM1401 implements a special algorithm that accounts for changes in the rate of sound propagation in metal induced by temperature.

The EM1401 electromagnetic acoustic thickness gauge 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.

Various surfaces

Works both on flat surfaces and on surfaces with a radius of curvature of 10 mm and more

EMAT technology

The technology enables thickness measurement with no couplant and preliminary surface cleaning

High-temperature transducer (on request)

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

Tilt angle makes a minor effect on the device’s readings, in contrast to conventional thickness gauges with piezoelectric transducers that require transducer fixed in a certain position.

The EM1401 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 allows using manual measurement modes based on the first echo and difference between any two echoes. Manual mode is recommended for severely corroded objects.

The EM1401 allows measurements:

• without usage of couplant
• without surface preparation
• after a single button touch
• through the operating gap up to 6 mm
• both on flat surfaces and on surfaces with a radius of curvature of 10 mm and more
