Description

The EM1401 EMA thickness gauge is designed for thickness measurements of steel pipes, sheet metal, rods and other products made from steel, aluminum and other metals with operating clearance of up to 6 mm between the sensor and metal. Operation of the thickness gauge requires no preliminary surface preparation, no couplant is required. The clearance can consist of dirt, layer of rust, layer of salt deposits or other non-conductive coating (paint, varnish, enamel, plastic, etc.).

The special EMT14014T sensor allows using the EM1401 thickness gauge for thickness measurement on objects heated up to 750 °C. The device implements a special algorithm that accounts for changes in the rate of sound propagation in metal induced by temperature.

Additional materials:

The sensor skew makes a minor effect on the device readings in contrast to conventional thickness gauges with piezoelectric transducers that require a sensor fixed in a certain position.

The EM1401 thickness gauge has a color display protected by shock-resistant glass. Like any other EMA thickness gauge produced by our company, the EM1401 thickness gauge uses a special data processing algorithm that provides automated 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 mode of thickness measurement, the device 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 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 strobes, select a thickness measurement mode, signal processing parameters, etc.
