90 Degree Indicating Analog Frequency Meter Vertical Installation Mounting
1. Application:
The moving coil, rectifier meters, WD 48/72/96/110/80 housed in molded polycarbonate cases are suitable for the measurement of AC currents and voltages. Moving coil rectifier instruments measure average values and are calibrated to indicate RMS values, assuming a sinusoidal waveform for frequencies from 40 to 10000 Hz (AC current for frequency range of 40 to 1000 Hz and AC voltage for frequency range of 40 to 1000 Hz. These instruments offer several advantages in switchboards and generating set panels. A number of meters can be mounted in a panel cut-out (mosaic mounting). Front glass, bezel & dial can easily be replaced.
