Metallux sensors and resistors in the professional test-M by Gossen Metra power resistors provide high measuring accuracy. Foil sensors navigate safely the correct measuring range. Metallux products are indispensable in the new professional test-M from Gossen Metrawatt. The professional test is a universal measuring tool at the highest technical level. With a precision power resistor in thick-film technology, measurement accuracy is achieved and guarantees. A foil sensor ensures the correct measuring range.

For the high accuracy power resistors are characterised in thick film technology responsible. These resistors on steel substrate allow high power density in a confined space with its space-saving design. The core or main measurement tasks of the professional test is the determination of the internal resistance in electrical system of the building installation. With the meter can be located, whether the installed overcurrent protection device can disable safely in case of short-circuit. The used resistors allow an increase of the measurement current and cause this a larger drop in voltage of the network concerned. Therefore, more accurate measuring results can be achieved. The measurements are obtained through a knob.

With this control knob placed on the outside of the appliance, the selected position recognized by a foil sensor and retrieve the desired function. The film sensor (membrane sensor) MetPot is above all due to its flat shape and a wide temperature range for the integration into the professional test. The Metallux sensors feature reliability even under difficult conditions. Precision power resistors Metallux produces various power resistors in thin film and wire technology. With different substrates and forms are used. Power resistors are used in energy production in transport engineering, drive and control technology. Special features like lowest inductance and extremely high heat capacity, open new perspectives in power electronics. Variable resistance values, arbitrary geometries and universal connection variants round off the product family. Precision potentiometers Metallux produces standard potentiometers and customized solutions in plastic, aluminium and stainless steel.
