FREQUENCY
METERS |
 |
 |
| NIPPEN's
Frequency Meters are of two types : |
|
1)
Vibrating Reed Type
Frequency Meters
|
|
| 2)
Transducer type, Pointer Frequency Meters |
|
|
|
|
VIBRATING REED TYPE
FREQUENCY METERS
|
|
| The
vibrating reed frequency meter has steel
reed elements in the field of an electromagnet.
The reeds vibrate in resonance with the
energizing Alternating Current of this electromagnet.
Meters are manufactured having 11, 13 or
21 reeds. Only the individual reed, whose
natural frequency corresponds with the frequency
of the A.C. supply, will vibrate at full
amplitude indicating the correct frequency
on the dial. When two reeds show deflection
of the same amplitude the mean of the two
gives the correct frequency. |
