MA19 Moving-coil meters

Moving-coil meters MA16, MA17, MA19 and MA12 types are destined to measure d.c. voltage or d.c. current and other physical quantities converted into a current or voltage standard signal.

 

Description

Lumel MA19 moving-coil meters are designed to measure current or DC voltage. Magnetoelectric meters with built-in rectifier type MA12P, MA17P and MA19P 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 device, 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 non-sinusoidal course is appropriately characterised, this measurement error is calculated.

Therefore, the requirements for the influence of the shape of the curve for the medium-responsive instrument (straightened) are not specified in the standard EN 60051-2.

MA19 moving-coil meters are suitable for mounting in a panel thickness not exceeding 25mm in the holes.
