Verify Vibration Linearity, Accuracy, & Shutdown Logic in Seconds

Our new firmware upgrade, CALROUTE , for portable vibration calibrators and shaker tables from The Modal Shop allows users to pre-program test points and set pass/fail guidelines, simplifying the loop check and calibration process.
Testing the vibration monitoring system per API 670 is time consuming and repetitive. Many instrumentation channels have the same alert and alarm thresholds. Thus technicians are constantly dialing in the same amplitude levels and test speeds for multiple sensors. CALROUTE firmware allows those repetitive tests to be pre-programmed into the device. Once programmed, I&C personnel can test system linearity, accuracy and shutdown logic in seconds.
CALROUTE is available on both The Modal Shop's Model 9100D and 9110D Portable Vibration Calibrators. When using the feature to test the sensitivity of a vibration sensor on Model 9110D Portable Vibration Calibrator, the user receives instant pass or fail notification after each test point. Technicians who are new to vibration can effectively test instrumentation without worrying about tolerances or deviations, which can be complex and change based upon frequency.

Customers with firmware version 5.1.1 or higher can add CALROUTE to their portable calibrators without returning them to our facility. To see how this new innovation works, watch a test utilizing CALROUTE.

  • Of course, if you want to learn how to analyze vibration, Mobius offers an array of impressive programs from online to in-person. You can read about their new iLearnReliability™ program in Yahoo Finance. On an unrelated note, I met Jason Tranter at SMRP 2015 when it was in Cincinnati and he said 'you are the guy from the proximity probe testing videos.' Ironically, Jason's orbit plot video helped me understand how those sensors work long ago.

  • What do you take into the field with you? As a vibration analyst, you can't always carry all your vibration analysis tools. The Digiducer, a USB accelerometer, can be tossed in a bag or pocket, plugged into a cell phone, and can start collecting data or even performing a quick real-time diagnosis.
Tip of the Quarter

Have you ever used an accelerometer and portable vibration analyzer to validate the signal from a 4-20 mA vibration transmitter that sends an "overall" vibration level measurement to your DCS or PLC? If so, you probably have noticed the two measurements can be a little (or a lot) different. The difference can usually be attributed to filtering, signal processing, and mounting.

If you find yourself in this situation, take a look at this "Tips from Techs," written by Meredith Christman of IMI Sensors, called " Understanding Current Output Signals - RMS, Peak and True Peak."
