The EM4000 EMA thickness gauge is designed for thickness measurement on steel pipes, sheet metal, rods, and other products made from steel, aluminum and other metals, with a operating gap of up to 3 mm between the sensor and metal. Operation of the EMA thickness gauge requires no preliminary surface preparation, no couplant is required. The gap can consist of dirt, layer of rust, layer of salt deposits or other non-conductive coating (paint, varnish, enamel, plastic, etc.). In addition to measuring metal thickness, the EM4000 allows measuring the thickness of non-conductive coating on metal.
A special sensor allows using the EM4000 thickness gauge for thickness measurements on objects heated up to 750 °C. Skew makes a minor effect on the device’s readings, in contrast to conventional thickness gauges with piezoelectric transducers that require sensor fixed in a certain position. The EM4000 thickness gauge has a color display protected by shock-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. The algorithm developed by our experts allows reducing the human factor and simplifying the device interface.
The EM4000 electromagnetic acoustic thickness gauge is capable of connecting to a tablet, smartphone or another device based on the Android OS. This allows expanding the thickness gauge features, analyzing A-scans, B-scans, working with strobes, selecting a thickness measurement mode, signal processing parameters, etc. The EMA thickness gauge can be connected to a tablet either wirelessly via Bluetooth or using a USB cable.
