Moving Iron Instruments are generally used for measuring AC Voltages and Currents. A feature of the moving element is that it is fitted with synthetic sapphire jewels. The movement is light and quick-acting, but extremely robust. An efficient system of fluid damping is employed. The movement is efficiently shielded against the effect of external magnetic fields. Moving Coil Instruments are used for measuring DC values. They can be used too on AC systems , if the input is fed through bridge rectifiers. A Centre magnet system is incorporated in our moving coil instruments which completely shields the movement from the effect of external magnetic fields. The movement is pivoted between synthetic sapphire jewel bearings for frictionless operation. The above meters can be used for higher ranges by using necessary Current and Potential transformers, and external shunts, Accuracy Class: 1 to 1.5% as per ISS 1248/83, we also manufacture.

DESCRIPTION:- Moving coil instruments with circular scale of 240° employ a platinum taut band for suspension of moving coil assembly instead of pivot & jewel system. It is less prone to sluggishness & zero shift due to frictionless movement. These meters are basically used for the measurement of DC current & voltage, and can be used with built in rectifier for the measurement of AC current & voltage in the frequency range 45~65Hz. / 400Hz. The meters measure average value. It can be scaled to indicate RMS values (on request). These instruments are not recommended for non-sinusoidal waveforms of current & voltage. The other indications like Frequency, Power & Power factor can be offered with suitable external transducers. Speed indication is possible if used with AC tacho-generator (not in the scope of AE).
