CE Approve Maximum demand Analogue Panel Meters With Accuracy
Series Maximum Demand Ammeter is a bimetal instrument. The
bimetallic movement responds and indicates the mean RMS current
loading over a specified period of time. A black pointer which is
attached to the bimetal spiral moves in response to the current (
heating) in the bimetal spiral. A red pointer (slave or memory
pointer) is driven by the black pointer. The red pointer remains at
its maximum position to which the black pointer has reached during
any period of time. Further, when the loading is reduced, the red
pointer remains at the maximum value. This enables the operator to
know the maximum loading of the system without continuously
watching the meter. A zero corrector is provided on the front of
the meter to bring back the red pointer to the position of the
black pointer. A sealing/locking facility is also provided on the
zero corrector to prevent tampering of the reading at the red
Changeable scale plate: Draw out the dial with a suitable tool
introduced in the dial perforation. When replacing the new dial,
carefully close the slot of the case with the plastic cover. The
dial is changeable without influence the accuracy.
The casings and frames for all instruments are made of self
extinguishing ABS, according to UL94, with high impact resistance.
The bases are made from self extinguishing reinforced PPO,
according to UL94, with high impact resistance and maximum
Due to analogue panel meter is a kind of precision measuring
instrument, we strongly recommend our customers choose ocean
shipping, then we can make firm wood pallet for certain cases to
protect the goods against probable rough handling in the
