Description

The Bently Nevada 3500/53 133388-01 is an electronic overspeed detection module designed for the 3500 Series Machinery Detection System. This module provides a highly reliable, fast-response, redundant tachometer system specifically engineered for overspeed protection applications. It is designed to comply with American Petroleum Institute (API) Standards 670 and 612. The 3500/53 modules can be configured to form 2-out-of-2 or 2-out-of-3 (recommended) voting systems, requiring a 3500 rack equipped with redundant power supplies.

Features

• Redundant tachometer architecture for critical machinery protection.
• Fast response time for emergency shutdown (ESD) applications.
• Configurable for 2-out-of-2 or 2-out-of-3 voting logic.
• Designed to meet API 670 and 612 overspeed protection requirements.
• Integrated buffered output for signal testing and recording.

Applications

• Power Generation: Large turbine power generation units in thermal, nuclear, and combined cycle power plants.
• Oil & Gas: Refineries, LNG stations, and critical chemical plant rotating equipment.
• Industrial: High-speed rotating equipment including blast furnace blowers, large electric motors, generators, and fans.

Technical Specifications

Installation Guidelines

• Safety First: Always power down the 3500 rack before inserting or removing any module to prevent electrical damage or unintended system trips.
• ESD Handling: Use proper electrostatic discharge (ESD) grounding procedures when handling the module to protect sensitive internal circuitry.
• Wiring: Connect transducer signals (proximity probes or magnetic pickups) to the designated I/O module terminals. Ensure relay output wiring to the ESD system is secure and verified.
• Signal Routing: Route signal cables away from high-EMI sources to maintain measurement integrity.
• Rack Seating: Ensure the module is fully seated and the front panel screws are tightened to maintain proper ground connection and mechanical stability.
