Description
Lumel MA17P, MA19P and MA12P Moving-coil meters with built-in rectifiers are designed to measure a.c. voltage or a.c. current converted into a current or voltage standard signal.
The MA17P Moving-coil meters are intended for measuring the effective currents and alternating current with sinusoidal waveform. Measurement of the current and voltage of the non-sinusoidal waveform is subject to a large error proportional to the degree of deformation of the waveform, what follows from the principle of measuring the rectifier devices which reacts to the average value of the straight-run, but it is calibrated like this to indicate the effective value of the sinusoidal waveform. Where the noninusoidal course is appropriately characterised this measurement error is calculated.
Lumel are the producers of automation devices for measurement, control, transmission and visualisation of various industrial processes. They also provide Services of designing and manufacturing of automation systems.
Since 1954 Lumel brand has been known as a producer of quality measuring devices and high-pressure die-casting all over the world. Their high position in the market has been achieved thanks to continuous development, employees and modern technology in areas of research, design and production. Lumel delivers complex solutions for power and industrial automation sector as well as for automobile, chemical, steel, or HVAC industries
Their objective is to provide comprehensive solutions by designing intelligent systems based on the electronics Lumel manufactures, which are measuring and regulating equipment for industrial, automotive and military applications, as well as through service production of electronics.
