Description
| The 3300 Series meter relays offer a wide
variety of applications in control, alarm, and limit use. Photo
conductor sensing eliminates all interference with the indicating
meter. These relays incorporate an amplifier input that drives a
rugged high-torque pivot and jewel meter. Metal-cased "Rugged
Seal" construction withstands rigorous environmental conditions.
The metal cover with a drawn steel plated rear case gives complete
magnetic isolation for steel panel mounting. In addition, each meter
is moisture, dust, and dirt proof for use in wash-down areas. Fail-safe
circuitry opens output relays in the event of power failure. Two
different sizes, 3-1/2" and 4-1/2", are available in both
single and dual set point models.High-gain transistor switch circuitry
provides accurate switching with a “dead band” of no
more than 0.5% of full scale (F.S.). All AC current units offer
±3% of accuracy F.S. This style meter is ideal for many other
electrical functions. |
