2 Predictive Maiteace Motor Vibratio Moitorig vibratio o iductio motors forms part of the core of ay predictive maiteace program. Typical applicatios demad vibratio measuremets i the horizotal, vertical ad axial directio o both the iboard ad outboard motor bearigs. Aside from typical mechaical issues, such as misaliged coupligs ad ubalace, the vibratio aalyst ca also detect electrical issues that cause mechaical vibratios. Some commo electrical faults iclude air gap variatio, broke rotor bars ad bearig flutig. Vibratio aalysts ca use oe accelerometer, mouted magetically ad rotate it aroud the motor to capture various data collectio poits. I some cases the motor is i a iaccessible locatio ad thus permaet mout sesors are used ad routed to a juctio box for walk up data collectio. Accelerometers are permaetly mouted by drillig ad tappig ito the motor housig or they ca be adhesively affixed or welded usig a moutig pad.

4 Process Moitorig & Protectio Motor Vibratio Electric motors drivig capital machiery ad acillary equipmet are critical plat processes. Uscheduled shutdows or failures result i costly dowtime, equipmet damage ad possible safety hazards for persoel. Although your maiteace egieers ca t be everywhere at oce, IMI vibratio ad fault trasmitters provide cotiuous protectio ad early detectio of issues such as soft foot, imbalace, bearig faults, bearig flutig ad misaligmet. Usig a 4-20 ma sigal, our trasmitters directly commuicate with customer PLC, PI, SCADA, or DCS systems ad data ca be easily treded, maaged, with proper alerts ad otificatios to keep your process up ad ruig ma Trasmitters - Process Moitorig & Protectio Vibratio Trasmitter Model 682B03 Outputs 4-20 ma sigal proportioal to acceleratio, velocity, or displacemet ICP accelerometer iput Aalog vibratio output via frot BNC See page 117 for more iformatio 4-20 ma Output Sesor Model 640B01 Available i top or side exit casigs Peak or RMS, or velocity Itrisically safe/explosio proof versios available See page 108 for more iformatio 24 VDC Power Supply Model 682A to 230 VAC powered 1000 ma maximum See page 138 for more iformatio DIN Rail Eclosure Model 682A00 Strog fiberglass costructio NEMA 4X ratig Visit for more iformatio Recommeded Compoets for a Typical Istallatio 4-20 ma Sigal Cable PLC, DCS, Alarm, or SCADA System Sesor Cable Aalog Sigal Cable Sesor Cable Permaetly Istalled, Low Cost, ICP Accelerometer Vibratio Trasmitter, Aalog Sigal Iput, 4-20 ma ad Aalog Sigal Outputs Vibratio Data Collector or FFT Aalyzer for Sigal Aalysis ad Diagostic Purposes 4-20 ma Vibratio Sesor PLC, DCS, Alarm, or SCADA System

5 Motor Vibratio Bearig Fault Detector - Process Moitorig & Protectio Bearig Flutig i Electric Motors Bearig flutig occurs whe curret is passed through the motor bearig istead of a grouded source. PWM (Pulse Width Modulated) drive switchig frequecies result i udesirable motor shaft currets, a side effect that causes bearig damage icludig pittig ad flutig. The pittig ad flutig will result i udesirable bearig vibratio. Because the Bearig Fault Detector s additioal fault output is extremely sesitive to high frequecy impactig, it provides a early idicatio that pittig or flutig has occurred. This will allow your motor to be serviced before catastrophic damage occurs. Bearig Fault Detector Model 682B05 Provides early warig of bearig ad gear faults Operates with PLC, DCS, SCADA, alarm ad cotrol systems Outputs 4-20 ma sigals for peak acceleratio ad overall vibratio See page 120 for more iformatio
