Product Detail

Display-free monitoring unit with vibration, displacement and temperature measurement, relay interlock, 4-20mA and dual Modbus communication, intrinsically safe for hazardous areas, tested surplus spare parts

Product Overview

PN: 1900/65-00-01-03-01-01
Brand: Bently Nevada (Baker Hughes)
Series: 1900 General Purpose Monitor
Type: No-display standalone protection monitor
Function: Independent of 3500 rack system, it collects signals from proximity probes, velocity sensors, accelerometers, thermocouples and RTDs to monitor vibration, position, rotating speed and bearing temperature. Set alarm thresholds via PC software, output relay trip signals and 4-20mA data, upload readings through Modbus TCP/RTU and store fault logs for troubleshooting.
