Simpson Electric 3300 Series Rugged Seal Meter Relay - AC Volt Meters


Maximum 100 characters

The Simpson Electric 3300 Series analog 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. Available in both 3½" and 4½" sizes, these meters feature both single and dual set point options.
