Product Introduction & Positioning
The 3500/72 140482-01 is a four-channel Reciprocating Rod Position Monitor I/O module equipped with external terminations. It accepts inputs from proximity transducers attached to reciprocating compressors, conditioning these signals to provide reliable dynamic and static measurements. Programmable alarm setpoints allow operators to monitor critical parameters, such as rod position and rod drop, triggering alarms or control actions as necessary. Positioned within Bently Nevada’s 3500 Series machinery protection system, it integrates seamlessly with other system modules to offer comprehensive compressor condition monitoring. Its external termination design simplifies wiring and installation within control racks, while the module’s high precision and reliability make it indispensable for plant operators focused on optimizing maintenance and preserving asset health.
Key Technical Features & Functional Benefits
The module provides four separate input channels, each capable of dynamic and static measurements that encompass important reciprocating compressor conditions. It supports configurable alarm thresholds with alert and danger setpoints tailored to application-specific needs. The signal conditioning circuitry ensures high accuracy, with typical position amplitude accuracy within ±0.33% of full scale and position angle accuracy within ±1° typical.
Operating reliably in industrial temperature ranges from -30°C to +65°C, the 3500/72 140482-01 module tolerates harsh plant environments and supports relative humidity up to 95%, non-condensing. It consumes nominal power and fits standard 3500 Series racks, facilitating straightforward integration and maintenance. With its external termination interface, field wiring becomes more accessible, enhancing installation efficiency and reducing potential wiring errors.
The module’s compliance with API 618 requirements and its detailed analytics for rod position, rod drop, and hyper-compressor detection enable robust safety and condition monitoring protocols. Maintenance teams employ its precision data for early fault detection, supporting predictive maintenance frameworks that extend compressor operational life.
