Bently Nevada 3500/62 Sensor Vibration Speed

The 3500/62 Process Variable Monitor is a specialized 6-channel monitor designed for continuous monitoring of critical machine parameters such as pressures, flows, temperatures, and levels. This monitor ensures the ongoing health of machinery by accepting both current and voltage inputs, conditioning these signals, and comparing them to user-programmable alarm setpoints.

Key Features:

1. Versatile Input Acceptance:
   • Accepts +4 to +20 mA current inputs or any proportional voltage inputs between -10 Vdc and +10 Vdc, accommodating various signal sources.
2. Signal Conditioning:
   • Conditions input signals to ensure accuracy and reliability in continuous monitoring.
3. Alarm Setpoint Comparison:
   • Compares conditioned signals to user-programmable alarm setpoints, driving alarms for machinery protection.
4. Continuous Parameter Monitoring:
   • Continuously compares monitored parameters against configured alarm setpoints, providing real-time information for machinery protection.
5. Operational and Maintenance Information:
   • Provides essential machine information for both operations and maintenance personnel, aiding in informed decision-making.

Programming Options:

1. Current or Voltage Measurements:
   • Programmable using the 3500 Rack Configuration Software to perform either current or voltage measurements, allowing customization based on monitoring requirements.
2. Signal Input Scenarios:
   • Offers I/O modules for three signal input scenarios: +/-10 Volts DC, isolated 4-20 mA, or 4-20 mA with Intrinsically Safe zener barriers.
3. Intrinsically Safe Power:
   • The Internal Barrier I/O provides external power input terminals for supplying intrinsically safe power to 4-20 mA transducers.

Triple Modular Redundancy (TMR) Configuration:

1. Grouped Installation:
   • In TMR configuration, Process Variable Monitors must be installed adjacent to each other in groups of three.
2. Dual Voting Mechanisms:
   • Employs two types of voting to ensure accurate operation and to prevent loss of machinery protection due to single-point failures.

Conclusion: The 3500/62 Process Variable Monitor stands as a crucial element in ensuring machinery safety by providing continuous monitoring and timely alarms for critical parameters. With its versatile input acceptance, signal conditioning, and flexible programming options, this monitor serves as a valuable tool for both operations and maintenance personnel. In TMR configurations, the dual voting mechanisms further enhance reliability and accuracy in machinery protection.
