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 placed 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.

Available in sizes: 72mm, 96mm & 144mm square panel mounting type.
Range: 45-50-55 Hz, 47-50-53 Hz
Voltage: 110V or 230V or 440V
Accuracy: ± 1% as per ISS 1248/83


TRANSDUCER TYPE POINTER FREQUENCY METERS

The Specification is same as that of the Vibrating Reed Type Frequency Meters.
