3300/50-02-01-00-00 Bently Tachometer Monitor

Description 3300/50-02-01-00-00 Bently Tachometer Monitor Product Dimensions： Product Description (Detailed Explanation) The 3300/50 Tachometer Monitor provides continuous machinery speed measurement and protection. It receives input signals from various transducers, most commonly the 3300 Proximitor (proximity probe) or magnetic pickups. The monitor converts these pulse inputs into a digital speed readout and analog signals for DCS/PLC integration. This specific configuration (3300/50-02-01-00-00) indicates: -02: A 4 to 20 mA Recorder Output. -01: An Epoxy-sealed logic/backplane interface. -00: Standard Agency Approvals (Non-hazardous). -00: Standard Internal Safety Barriers (None). The unit is essential for detecting dangerous conditions such as overspeed or unexpected machine stops (Zero Speed) in large turbines, compressors, and pumps. Product Parameters (Technical Specifications) Parameter Category Specification Input Signal Proximity Probes (Proximitor) or Magnetic Pickups Input Frequency 0.017 Hz to 20 kHz (Speed dependent) Speed Range Configurable from 1 to 99,999 rpm Recorder Output 4…20 mA DC (Proportional to speed) Display Type 4.5-digit LCD (Backlit) Accuracy $\pm 0.1\%$ of full-scale range Relay Outputs Two mechanical relays (Alert and Danger) Buffered Output Front panel BNC connector (Raw transducer signal) Power Consumption Typically 3 Watts Product Advantages (Key Benefits) Critical Machinery Protection: Provides instantaneous overspeed protection, which is vital for preventing catastrophic mechanical failure of high-speed rotors. Zero-Speed Detection: Accurately identifies when a machine has come to a complete stop, which is a safety requirement before engaging turning gears or starting maintenance. Buffered Signal Access: The front-panel BNC connector allows technicians to connect portable vibration analyzers (like the Scout or 2140) without disconnecting any internal wiring. Rugged Reliability: The 3300 series is famous for its “built-to-last” design, often operating for over 30 years in harsh power plant and refinery environments. Triple Modular Redundancy (TMR) Support: Can be integrated into voting logic systems to increase the overall safety integrity level (SIL) of the plant. Precautions (Important Notes) Keyphasor® Alignment: For accurate speed monitoring, the proximity probe must be correctly gapped ($1.27\ mm$ or $50\ mils$ typical) relative to a notch or projection (Keyphasor) on the shaft. Gap Voltage: Before commissioning, always verify the transducer gap voltage (typically $-9V$ DC for a standard Bently probe). Incorrect gap will cause “Invalid Signal” or “OK Light” failures. Logic Configuration: Ensure the “Danger” relay logic is set correctly (Latching vs. Non-latching) according to your plant’s safety protocol to prevent unintended machine restarts after a trip. Legacy Support: Note that the 3300 system is a legacy product (succeeded by the 3500 system). Ensure spare parts and power supplies are compatible with existing 3300 racks. Product Applications (Typical Use Cases) Steam & Gas Turbines: Continuous overspeed protection and speed monitoring during the startup/ramp-up phase. Centrifugal Compressors: Monitoring rotor speed to ensure the machine stays within the surge-free operating window. Cooling Tower Fans: Detecting motor or gearbox failures via zero-speed monitoring. Pumps & Agitators: Used in chemical processing to ensure consistent flow rates by monitoring driver speed. Hydroelectric Generators: Monitoring low-speed rotation and creep during shutdown sequences.
