FREQUENCY METERS
POINTER TYPE
REED TYPE
Size : 96 x 96 mm
Size : 72 x 72 mm
BEE Frequency Meters are used to measure the applied frequency. They come as Pointer Type with built in Transducer &
Vibrating Reed Type. Vibrating Reed Type Frequency Meters indicate the supply frequency by means of individual reeds,
when rated voltage ± 20% is applied across the terminals of the meter, the particular reed, whose natural frequency of
vibration coincides with the supply of frequency, vibrates with full amplitude. In case the supply frequency falls midway
between two reeds both the reeds vibrate, at reduced amplitude. The amplitude of vibration at the tip of reeds is high
enough for a distinct indication. The Pointer Type Frequency Meter has a clear, well defined scale marking at 90 degree
angle. The pointer indicates the applied frequency when voltage is applied across the terminals of the meter.

INSTALLATION :
The best performance is guaranteed if the following points are observed:
?
Shunts may be mounted horizontally or vertically. Horizontal mounting gives the best heat
dissipation.
?
Utilize the full end block surface area.
?
Ample ventilation should be provided.
?
Busbar should be adequately rated, cleaned and coated with a thin layer of silicon grease applied to
BEE Light Weight Shunts :
Light Weight Shunts are suitable for application where there is space and weight
limitations such as in Portable Instruments, Compact Electronic Equipments, Power
Electronics and in Mobile Installations such as Aircrafts, Tanks, etc.
