PRODUCT DESCRIPTION
Rotor speed monitoring tachometer
Bently Nevada 3300/50-02-01-00-00 is a rotor speed tachometer. The tachometer measures rotor speed from transducer pulses and presents the result locally, with outputs for recording and annunciation. Its documented variants provide different speed-related functions. It must not be used as a speed controller or as an overspeed-protection device.
The first option selects the zero-speed tachometer and the relay option specifies epoxy-sealed contacts. No agency approval or internal barrier is requested. Zero-speed operation requires two compatible transducers, a manual threshold and the documented enable and voting arrangement.

ROTOR SPEED MONITORING TACHOMETER
Integrating 3300/50-02-01-00-00
The tachometer measures rotor speed from transducer pulses and presents the result locally, with outputs for recording and annunciation. Its documented variants provide different speed-related functions. It must not be used as a speed controller or as an overspeed-protection device.
The original manual describes compatible Proximitor or system Keyphasor inputs. Magnetic pickups are not permitted for the zero-speed function, and automatic threshold is not allowed in that version. Match the selected tachometer type, transducer conditioning and rear signal-input relay module.
Follow the 3300 system installation instructions and the tachometer maintenance manual identified by the original operation guide. Check the selected input, threshold, enable contacts and relay wiring. Analog outputs and speed Alerts are not a substitute for an independent overspeed-protection system.
Features:
- Match complete order, installed input and output configuration, wiring and installation instructions
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 3300/50-02-01-00-00 rotor speed tachometer requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 3300/50-02-01-00-00 requires comparing complete order, installed input and output configuration, wiring and installation instructions. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
The original manual describes compatible Proximitor or system Keyphasor inputs. Magnetic pickups are not permitted for the zero-speed function, and automatic threshold is not allowed in that version. Match the selected tachometer type, transducer conditioning and rear signal-input relay module.
A 2011 manufacturer notice placed 3300 monitors in repair-only Phase 4, subject to component availability, and estimated transition to unsupported Phase 5 in January 2014. That estimate is not confirmation of the actual transition date for this exact order. The notice explicitly excluded 3300 I/O modules. No delivered hardware revision or unconditional successor compatibility is established.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 3300/50-02-01-00-00 rotor speed tachometer requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 3300/50-02-01-00-00
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How is 3300/50-02-01-00-00 identified?
The first option selects the zero-speed tachometer and the relay option specifies epoxy-sealed contacts. No agency approval or internal barrier is requested. Zero-speed operation requires two compatible transducers, a manual threshold and the documented enable and voting arrangement. -
What is the function of this component?
The tachometer measures rotor speed from transducer pulses and presents the result locally, with outputs for recording and annunciation. Its documented variants provide different speed-related functions. It must not be used as a speed controller or as an overspeed-protection device. -
Which equipment and settings must match?
The original manual describes compatible Proximitor or system Keyphasor inputs. Magnetic pickups are not permitted for the zero-speed function, and automatic threshold is not allowed in that version. Match the selected tachometer type, transducer conditioning and rear signal-input relay module. -
What application does it support?
The tachometer calculates rotational speed from pulse timing and supplies front-panel indication and recorder output. The source restricts these outputs to measurement and annunciation, not speed control. -
What should be checked during installation?
Follow the 3300 system installation instructions and the tachometer maintenance manual identified by the original operation guide. Check the selected input, threshold, enable contacts and relay wiring. Analog outputs and speed Alerts are not a substitute for an independent overspeed-protection system. -
Can this tachometer replace an overspeed protection system?
No. The manufacturer explicitly prohibits using it independently or as a component of speed-control or overspeed-protection systems because it lacks the necessary protective redundancy and response characteristics. -
Why is a magnetic pickup unsuitable for the zero-speed version?
The original programmable-options table expressly prohibits magnetic pickups for zero-speed use. It also requires manual threshold operation; automatic threshold will not operate below 5 Hz in that historical implementation.
