Product Description
Description
The DD910 Style the long life single phase ammeter is a style with induction and used in measuring the electric power in the 50Hz or 60 Hz AC Circuit. The manufacture structure of this kind ammeter is reliable and the capability is steady all of the make it has the characters such as the long life, wide lode high precision, low power expense and nice shape. The machine can be serviced for 25 years

Main functional features
1. The electromagnetic system and magnetic circuit specially treated with the technology adopt the imported steady magnetic iron core made by the silicon sheet, which straighten the error curve of the meter.
2. The brake magnetic steel offers the biplane-cheek type construction, which can decrease the vibration caused by the parasitic torque on the rotating disk, and easily clean the dust in the magnetic steel.
3. The voltage coi8l is sealed by employing the epoxy resin against the affection of humidity, and adopts the insulated plastics in the voltage and current coils as the sheath, which ensures the meter's life and the electrical safety performance.
4. The meter bearing comprises of the suspended magnetic bearing and the hard graphite bush with self-lubrication, and offers the stainless steel needle guide construction, by which the friction torque is greatly decreased, with the stability and reliability of the meter increased.
