从China供应商批发进口3500/72m Bently Nevada/Origin:Usa — FOB条款

The 3500/72M is a reciprocating compressor impact velocity monitor module from Bently Nevada, offered by Moore Automation Limited Xiamen Office with stated USA origin. It forms part of the 3500 Series machinery protection platform, specifically engineered to detect and quantify mechanical impacts in reciprocating compressor crankcases, crossheads, and piston rod assemblies. The module processes signals from proximity probe or accelerometer inputs, converting vibration and impact events into alarm state information and trend data for condition monitoring. Standard input sensitivity and frequency response are calibrated for reciprocating machinery characteristics, with typical impact detection covering the range associated with mechanical looseness, bearing degradation, and rod reversal events. The 'M' suffix denotes a module revision with enhanced signal processing algorithms compared to earlier non-M variants.

Physical construction follows the standard 3500 Series single-slot module format, with front-panel BNC connectors for temporary diagnostic access and terminal blocks for permanent sensor wiring. The 3500/72M typically supports two independent impact/velocity channels per module, with each channel configurable for different sensor types and alarm logic. Signal conditioning includes integration and differentiation options for converting between acceleration, velocity, and displacement domains, with selectable filter bands to isolate reciprocating-specific frequency components from general vibration. Standard Bently Nevada specifications quote maximum transducer input voltage, probe target material requirements, and gap voltage ranges typical for eddy-current proximity systems. The USA origin stated by the supplier implies manufacture or original distribution through Bently Nevada's American supply chain, though buyers should verify provenance documentation.

Target applications span natural gas transmission, petrochemical process gas, and refrigeration compressor installations where rod drop, packing wear, and crosshead bearing failure represent critical failure modes. The module integrates with 3500 rack alarm relays for automatic protection trip functions, or outputs to plant monitoring systems via communication gateways. Users include operators of pipeline compressor stations, refinery hydrogen recycle compressors, and LNG boil-off gas compressors. Sourcing considerations for this specific listing include confirming whether the stated USA origin refers to manufacturing location or original distribution channel, verifying module firmware compatibility with existing 3500 racks installations, and clarifying whether the unit arrives as new surplus, refurbished, or unused stock with potential shelf-life considerations for electrolytic components.
