Description

The 3300/03 System Monitor manages keyphasor signal distribution, alarm setpoint adjustment, and data communication in industrial 3300 monitor racks. The 3300/03 System Monitor accepts up to four proximity probe keyphasor inputs with 10 kΩ input impedance and conditions signals up to 10 kHz with ±0.3% dynamic accuracy and ±0.2° phase accuracy at 25°C. Front panel buffered outputs provide four coaxial connectors with 100 Ω output impedance for direct connection to transducers or monitoring devices.

The 3300/03 System Monitor supplies user-programmable -24 VDC or -18 VDC power to keyphasor probes with short-circuit protection. Operating power is 2 W, rising to 4.6 W with serial interface options. RS422 communications support up to 38.4 kbaud over distances up to 1200 m (4000 ft). The 3300/03 System Monitor connects installed monitors to external communications processors via static and dynamic data ports, and supports optional SDI or DDI for integration with process computers, PLCs, and Bently Nevada machinery management systems, enabling centralized automation control.

Applications

Distribute keyphasor signals to multiple probes
The 3300/03 System Monitor provides conditioned keyphasor outputs via four front panel coaxial connectors, enabling direct connection to four proximity probes for turbine, compressor, or motor monitoring.

Adjust alarm setpoints directly from the front panel
With built-in Up/Down controls, the 3300/03 System Monitor allows operators to set alarm thresholds with ±0.3% dynamic signal accuracy without additional interface modules.

Transmit transducer data to control systems
Using RS422 communication at up to 38.4 kbaud over distances of 1200 m, the 3300/03 System Monitor sends process and vibration data to PLCs, DCS, or process computers in automation networks.

Integrate with Bently Nevada machinery management software
The 3300/03 System Monitor supports optional DDI ports for direct data streaming, reducing the need for external communication processors while maintaining signal accuracy.

Competitive Advantage

Provide precise signal conditioning for keyphasor inputs
The 3300/03 System Monitor achieves ±0.3% dynamic signal accuracy and ±0.2° phase accuracy at 25°C, ensuring reliable data for rotor speed and position calculations.

Support up to four keyphasor probes in a single module
The 3300/03 System Monitor conditions and distributes four independent signals, reducing the number of required modules for multi-probe installations.

Deliver low power operation for dense racks
Consuming only 2 W nominally, or 4.6 W with interface options, the 3300/03 System Monitor allows multiple units per rack without exceeding power budgets.

Enable long-distance RS422 data transmission
The 3300/03 System Monitor communicates up to 1200 m at 38.4 kbaud, enabling centralized monitoring of distributed automation equipment without signal repeaters.
