Overview
The Bently Nevada 3300/50-01-02-03-02 Tachometer Monitor is designed for precise speed measurement and overspeed protection in rotating machinery such as turbines, compressors, and industrial motors. It continuously tracks rotor speed, zero-speed conditions, and acceleration to ensure machinery operates within safe limits.
Supporting multiple sensor types—TTL, magnetic pickups, and eddy-current proximity probes—this module offers flexible integration across diverse industrial environments. It is API 670 compliant, making it suitable for high-integrity protection systems in petrochemical and power generation facilities.
For example, in a steam turbine system, the 3300/50 monitor continuously checks shaft speed and initiates shutdown logic when overspeed thresholds are exceeded to prevent severe mechanical failures.
