Yokogawa 3500/60 133811-01 with Vibration Monitor Card Pack 136711-01 - Dual-Channel Vibration Monitor
Description:
The Yokogawa 3500/60 133811-01 is a Dual-Channel Vibration Monitor module that operates with the specific Vibration Monitor Card Pack 136711-01. This combination forms a key monitoring channel within the Yokogawa 3500 Machinery Management System. It is specifically designed to monitor the overall vibration levels of machinery using signals from proximity probes (for shaft relative vibration) or seismic transducers (for casing/bearing absolute vibration). The module conditions the input signal, processes it, and provides continuous monitoring of key parameters like Gap Voltage (for probes) and overall vibration amplitude. It features configurable alert and danger setpoints, which can trigger alarms and initiate protective shutdowns via relay modules in the same rack, making it a fundamental component for machinery protection.

Application Scenarios
The 3500/60 module is a versatile and widely used component for general machinery protection across various industries. Its application scenarios include:
Shaft Relative Vibration Monitoring:
Used on turbines, compressors, and large pumps to monitor radial shaft vibration using proximity probes. It detects conditions like unbalance, misalignment, and shaft instability, triggering alarms before damage occurs.
Casing Vibration Monitoring:
Monitors overall casing or bearing cap vibration using velocity sensors or accelerometers. This is crucial for machines like fans, motors, and gearboxes where bearing health and mechanical looseness are primary concerns.
General Purpose Machinery Protection:
Serves as the primary vibration monitoring channel for a wide range of critical and auxiliary machinery in a plant, providing the essential "first line of defense" by generating alerts and danger trips.
Integrated Protection System:
Works in conjunction with other 3500 modules (like the 3500/42 Relay module) within the same rack. The vibration levels processed by the 3500/60 are used to command the relays to activate alarms or initiate a safe machinery shutdown.
Power Generation and Oil & Gas:
Extensively used in power plants for boiler feed pumps, fans, and smaller turbines, and in refineries for various pumps and compressors, ensuring their operational integrity and preventing catastrophic failures.
