Datasheet
BentlyNevadaMachineryCondition Monitoring 177232 Rev. O
Description
The177230Seismic Transmitter is a simple, loop-powered devicethat can bequickly and easily installed. It can be integrated into your programmablelogic controller (PLC) or controls system linked to a plant asset condition monitoring solution. Its simpledesign reduces training, maintenance, and servicecosts. Thetransducer helps you better manage downtime, optimizemaintenanceplanning, and avoid unforeseen catastrophic failures ofmachinery assets.
The177230Seismic Transmitter incorporates robust CM design for reliability and implements an industry-standard 4 to 20mA loop-powered transmitter.
Easily Installed and Integrated
•Interfaces with PLCs and controlsystems (including DCS and SCADA)
•Requires only a short learning curvefor operations and maintenance–through a familiar interfacesimilar to that for connecting other PLCor controlsystem inputs
•Requires no field configuration or adjustments
•Needs few additionalparts for a completesystem
•Includes technicalsupport for customers on how to monitor their equipment
•Includes self-test
•Incorporates protected interface
•Supports a variety ofinterfacecables
Data Quality
•Provides accurateand repeatabledata
•Uses simpledata format
•Provides raw vibration signalfor verification and analysis
