The Bently Nevada 3300/50-02-01-00-00 is a Zero Speed Tachometer Monitor designed for critical machinery rotative speed and condition monitoring within the 3300 System platform. Operating as a single-channel monitoring module, it accepts dual transducer inputs and utilizes internal voting logic to prevent false trip indications caused by a single sensor failure. The 3300/50-02-01-00-00 variant is configured specifically as a Zero Speed Tachometer (Type Option 02) with Epoxy Relay outputs (Alert Relay Option 01), CSA/NRTL/C agency approvals (Option 00 for standard applications without specialized certifications), and no internal safety barriers (Option 00).
The front panel features dual 5-digit LCD displays that output shaft rotative speed in RPM alongside probe gap voltage, providing operator visibility into operating parameters and transducer health. It includes BNC buffered transducer outputs on the front panel for diagnostic equipment hookup, along with user-programmable proportional analog outputs (current or voltage) on the rear terminal strip for plant recording systems.
While providing continuous monitoring, Alert status, and proportional analog feedback for data logging, the 3300/50-02-01-00-00 tachometer is designed strictly for machinery condition monitoring and annunciation. It is not engineered for independent use as an emergency overspeed protection or speed control system.
