Product Description
Bently Nevada 3500/72M 176449-08 4-Channel Reciprocating Rod Position Monitor
4-Channel Reciprocating Rod Position Monitoring for Reciprocating Compressors, Rod Position/Rod Drop/Hyper-Compressor Monitoring
1. Product Overview
The Bently Nevada 3500/72M 176449-08 is a 4-channel reciprocating rod position monitor for 3500 machinery protection systems, designed to monitor reciprocating compressor rod position, rod drop, and hyper-compressor motion via Bently Nevada eddy current proximity probe signals. It processes dynamic/static position measurements, compares them to user-programmable alarm thresholds, and triggers alerts to prevent catastrophic failures. Channels are programmed in pairs (Channels 1-2 & 3-4), supporting up to two monitoring functions simultaneously. With hot-swappable design, redundant power compatibility, and hazardous area certification, it is ideal for oil & gas, petrochemical, and heavy manufacturing industries, ensuring reliable protection for reciprocating compressors.
