Features:

  • Bently Nevada 3300/01 System Monitor Provides Keyphasor Signal Buffering, Alarm Management, And Voltage Monitoring For 3300 Racks
  • Supports Up To Two Proximity Probe Keyphasor Signals With User-Programmable -24 Vdc Or -18 Vdc Transducer Power
  • Features Front-Panel Coaxial Outputs, RS422-Compatible Communication Ports, And Self-Testing LED Indicators To Prevent False Alarms
The Bently Nevada 3300/01 System Monitor is engineered to centralize essential monitoring functions within a 3300 rack system, ensuring accurate alarm handling, reliable voltage supervision, and seamless Keyphasor® signal management. This system module prevents false alarms caused by potentiometer misadjustments or voltage fluctuations, protecting critical industrial machinery in sectors such as power generation, petrochemical processing, and heavy manufacturing.

With a nominal power consumption of 2 watts (or 3.6 watts with interface options), the Bently Nevada 3300/01 efficiently delivers regulated DC voltages from the front rack power supply. It accepts up to two proximity probe Keyphasor signals, which are buffered and made available at front-panel coaxial connectors for diagnostic or predictive maintenance equipment. User-programmable Keyphasor power (-24 Vdc or -18 Vdc) is short-circuit protected, offering flexible support for various transducer configurations.

The rear panel of the Bently Nevada 3300/01 System Monitor provides double-wide connectivity for primary power, Rack Inhibit, Trip Multiply, remote reset control, and connections to two transducers. It also offers computer-ready connections for Bently Nevada communication processors (TCP/IP or DDM), OK relay terminals, and serial interface connections. Front-panel LEDs indicate proper voltage operation, and any fault automatically inhibits rack alarms, reducing the risk of false triggers. With operating temperatures from 0°C to +65°C, storage from -40°C to +85°C, and tolerance for up to 95% noncondensing humidity, the Bently Nevada 3300/01 System Monitor is robust, reliable, and ideal for demanding industrial environments.

The 3300/01 Bently Nevada System Monitor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Bently Nevada 3300/01 System Monitor is specifically designed to centralize critical monitoring functions in a 3300 rack system, preventing false alarms and ensuring stable machinery protection. This module handles Keyphasor® signal conditioning, alarm setpoint monitoring, and voltage supply verification to minimize the risk of erroneous alarms that could result from potentiometer misadjustment or power fluctuations. By consolidating these core functions, the Bently Nevada 3300/01 System Monitor simplifies system management and enhances reliability for power generation, petrochemical, and heavy industrial applications.

Power-efficient, the Bently Nevada 3300/01 consumes only 2 watts, increasing to 3.6 watts when interface options are engaged. It accepts regulated DC voltages from the front rack power supply and provides user-programmable Keyphasor transducer power at -24 Vdc or -18 Vdc, which is short-circuit protected. The module can handle up to two proximity probe Keyphasor signals, buffered and available on the front panel via coaxial connectors, allowing connection to diagnostic or predictive maintenance instruments without additional interface hardware.

The rear panel of the Bently Nevada 3300/01 System Monitor features double-wide connectivity for primary power, Rack Inhibit control, Trip Multiply, and remote reset operations. It also provides direct connections for two transducers, computer-ready interfaces for Bently Nevada communication processors (TCP/IP or DDM), and terminals for the OK relay contacts and Serial Interface. The module continuously monitors critical voltage supply levels using self-testing, microprocessor-based technology, with front-panel LEDs indicating normal operation. Any voltage fault disables the rack alarm and prevents false alarms, ensuring reliable monitoring of connected machinery.

With an operating temperature of 0°C to +65°C and storage range of -40°C to +85°C, tolerating up to 95% relative humidity (non-condensing), the Bently Nevada 3300/01 System Monitor is robust and suitable for harsh industrial environments. By combining precise signal buffering, intelligent alarm management, and versatile connectivity, this module offers significant advantages over comparable system monitors for industrial machinery protection.
