Bently Nevada 3500/42 128240-01 Proximitor/Seismic Monitor
Manufacturer: Bently Nevada
Product Number: 3500/42 (128240-01)
Category: Four-channel Proximitor/Seismic Monitor (3500 System)
Number of Channels: 4
Input Types: Proximity probes, seismic sensors
System Compatibility: Bently Nevada 3500 system
Product Description
The Bently Nevada 3500/42 128240-01 is a high-performance Proximitor/Seismic Monitor module designed for machinery protection and condition monitoring within the 3500 system. It provides four independent channels that can accept input from proximity probes, velocity transducers, or accelerometers. The module delivers continuous monitoring of vibration, position, and seismic parameters to detect abnormal machine behavior at an early stage, ensuring safe and reliable operation of rotating and reciprocating equipment.
Main Features
-
Four independent channels for Proximitor or seismic inputs
-
Configurable for radial vibration, axial position, or acceleration measurements
-
Buffered transducer outputs available for advanced diagnostics
-
Programmable alarm setpoints with Alert and Danger levels
-
Direct interface with 3500 rack and system software
-
Redundant power compatibility for reliable operation
-
Meets API 670 requirements for machinery protection
-
LED indicators for module status and alarms
-
Hot-swappable design for ease of maintenance
