Product Overview

• PN: 1900/65A-00-01-01-01-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 1900 Standalone Machinery Monitoring System
• Type: Integrated Multi-Function Equipment Monitor

• Function: Compact standalone monitoring unit replacing rack-type 3500 system for auxiliary equipment. It accesses signals from proximity probes, velocity sensors, accelerometers, RTD and thermocouples, measures shaft displacement, casing vibration and bearing temperature. Users set Alert/Danger thresholds via front panel or configuration software, trigger relay trip interlock and analog signal output, upload data to DCS/PLC/System 1 via Ethernet Modbus, realize unattended online condition monitoring and fault protection for non-critical rotating equipment
