Bently Nevada 3300/50-02-01-00-00 Tachometer Module
The Bently Nevada 3300/50 is a precision tachometer module designed for the 3300 XL proximity transducer system. This dual-channel module converts proximity probe signals into accurate speed measurements for rotating machinery monitoring, providing critical data for turbine control, compressor protection, and predictive maintenance programs.
Why 3300 XL Tachometer Modules?
Accurate speed measurement is fundamental to machinery protection and performance optimization. The 3300/50 module delivers:
- Dual-Channel Design — Monitor two machines or redundant speed inputs with single module
- Wide Speed Range — Measure from 60 to 250,000 RPM with high accuracy
- Multiple Output Formats — 4-20mA analog, relay contacts, and buffered probe outputs
- Programmable Alarms — Configurable overspeed and underspeed setpoints
- Hot-Swappable — Replace modules without system shutdown in critical applications

Industrial Applications
Turbine Speed Monitoring
Monitor steam, gas, and hydro turbine speeds for control systems and overspeed protection. Dual-channel redundancy ensures safety in critical power generation applications.
Compressor Protection
Detect surge conditions, bearing failures, and rotor instability through continuous speed monitoring. Integrate with vibration and temperature sensors for comprehensive machinery protection.
Motor Control Systems
Provide speed feedback for variable frequency drives (VFDs) and motor control panels. 4-20mA output interfaces directly with PLCs and DCS systems.
Gearbox Monitoring
Track input and output shaft speeds to detect gear tooth damage, misalignment, and lubrication issues. Calculate gear ratios and detect slippage in real-time.
3300 XL System Integration
Complete Monitoring Solution
- Proximity Probes: 3300 XL 8mm or 11mm probes with extension cables
- Proximitor Sensors: 3300 XL proximitor for signal conditioning (if not using tach module buffered output)
- Mounting Rack: 3300 XL rack system (holds up to 4 quarter-height modules)
- Power Supply: -24 VDC rack power supply module

Typical Configuration
For dual-machine speed monitoring:
- 1 3300/50-02-01-00-00 tachometer module (this product)
- 2 3300 XL 8mm proximity probes
- 2 Extension cables (length based on installation)
- 1 3300 XL rack with power supply
- Alarm relay wiring to control system
Installation & Setup
Quick Start Guide
- Probe Installation — Mount proximity probe perpendicular to shaft, targeting gear teeth or keyphasor notch. Maintain 1mm gap (0.040 inch).
- Module Installation — Insert module into 3300 XL rack slot. Secure with front panel screws.
- Probe Connection — Connect proximity probe cable to module input connector. Verify polarity and shielding.
- Output Wiring — Wire 4-20mA output to PLC/DCS analog input. Connect relay contacts to alarm circuits.
- Configuration — Set speed range, alarm setpoints, and output scaling using front panel DIP switches or software.
- Calibration — Verify speed reading against known reference (strobe tachometer or encoder).
Configuration Parameters
- Teeth/Notches: Program number of gear teeth or keyphasor events per revolution
- Speed Range: Select appropriate range for application (low, medium, high)
- Alarm Setpoints: Configure overspeed and underspeed trip points
- Output Scaling: Map 4-20mA output to desired speed range (e.g., 0-3600 RPM = 4-20mA)
LED Indicators & Diagnostics
| LED | Color | Meaning |
|---|---|---|
| OK | Green | Module operating normally, valid speed signal |
| TX | Green (flashing) | Speed pulses detected, normal operation |
| ALERT | Yellow | Speed approaching alarm setpoint (warning zone) |
| DANGER | Red | Overspeed or underspeed alarm activated |
| BYPASS | Yellow | Module in bypass mode (alarms disabled) |
| FAULT | Red | Module fault (power, probe, or configuration error) |

Frequently Asked Questions
Q: Can I use this module with non-Bently Nevada proximity probes?
A: Not recommended. The module is calibrated for 3300 XL probes. Using other probes may result in inaccurate readings.
Q: What is the maximum cable length between probe and module?
A: Up to 9 meters (30 feet) with standard extension cables. Longer distances require signal conditioning.
Q: Can I monitor belt-driven equipment?
A: Yes, but install probe on driven shaft (not belt). Belt slippage will cause inaccurate readings if monitoring drive shaft.
Q: How do I set the number of teeth for speed calculation?
A: Use front panel DIP switches or configuration software. Count actual gear teeth or keyphasor events per revolution.
Q: Is this module compatible with 3300 NSv (newer system)?
A: No, 3300/50 is for 3300 XL system only. For 3300 NSv, use compatible tachometer modules.
