  FREQUENCY METERS
NIPPEN's Frequency Meters are of two types :  
1) Vibrating Read Type Frequency Meters
 
2) Transducer Type Indicating Frequency Meters  

 

VIBRATING REED TYPE FREQUENCY METERS

 

The element of vibrating reed frequency meter consists of steel reeds which are in the field of an electromagnet and vibrate in resonance with the energizing A.C. of this electromagnet. These are manufactured having 11, 13 or 21 reeds. Only the individual reed, natural frequency of which 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 between the two gives the correct frequency.

 
Available in sizes: 72mm, 96mm & 144mm square panel mounting type.
