Nippen electrical instruments co. Produces moving coil instruments. This is an iso 9001-2000 certified company. Moving coil instruments are used for measuring dc quantities. Moving coil instrument can be used on ac systems when fed through bridge rectifiers. Center 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 ct/pt and external shunts.
