JOURNAL RUNOUT MEASURING SYSTEM
Quotation and Description


Dear Customer

Thank you for your interest in our Runout Measurement System for measuring both Electrical Runout (eddy probe) and mechanical runout (LVDT probe) at the same time. The system is described below in detail. Please call for the lasted price and delivery.

This system measures both the Electrical Runout and Mechanical Runout. Electrical Runout is measured with an Eddy Current Sensor. There are several choices available for that sensor. Most customers have been selecting the Bently Nevada 3300 series Proximeter and probes. You can substitute with the B&K Vibro IN-085, or other another device you may prefer. The Mechanical Runout is measured with an LVDT probe. Tracking of the angle is managed by an incremental encoder running tangentially on the rotor, or driven by a belt. Therefore your shaft can be turned by hand without requiring constant speed.






EXTENT OF DELIVERY:

We include a windows 11 computer with all the software preloaded, and all the hardware necessary to take electrical and mechanical runouts at the same time, except for the means to support and rotate the rotor or shaft. The software license follows the interface box. Therefore, the software can be installed on any number of other computers owned by the end user. This is helpful for customers for have tight controls on computers connected to their network. The software is backwards compatible to Windows XP. Our 3 year warranty on the system also includes any computer we supply. Any version of Windows XP thru Windows 11 (without bit locker) will work.

Per API 610, we recommend using 90 degree V-blocks to support your rotor during measurement. That way you do not introduce any runout from rollers, and cross effect errors the you might see with V-blocks at different angles. We warn against using Teflon inserts on your V-block. Nylon should be used instead. This is because Teflon will work into the journal, making it very slick. When that happens, the oil does not stick as well and when the shaft is in service, you don’t get proper circulation of the oil all the way around the journal. The Standard System includes:

  • Eddy Current Probe and cable (Electrical Runout)
  • LVDT Mechanical Probe with nylon tip and cable (Mechanical Runout)
  • Calibrator for Electrical and Mechanical LVDT probes
  • Proximity switch and cable (key phasor to trigger start and end of revolution)
  • Quadrature encoder with index and cable (for providing live graphs)
  • Four (4) Magnetic base assemblies to mount the probes and encoder
  • Signal Conditioner/interface box
  • Windows 10 Portable Laptop Computer
  • Computer Interface Cable (USB)
  • Rugged, water proof Pelican carrying case. By Stormcase
  • Software and license
  • 3 year warranty and life time free software updates
  • One day of on-site training. (Travel expenses not included)



    • COMPUTER:

    We include a new Windows 11 computer. If you must use a computer supplied by your company, that computer must meet the requirements listed below. Any modern day computer will exceed these requirements, so long as it has a Type A USB port. We can install the software on other computers on-site during the training while your computer support staff watches the process. There is no discount for supplying your own computer because we would we have to support the software on a non-standard system, and allow additional time during the on-site commissioning.

  • Pentium 4 at 600 MHz or higher
  • 2 Gig RAM or more
  • Five (5) Gigabyte available space on the Hard Drive or more
  • Screen adjustable to a 1024x768 resolution
  • Ethernet interface
  • CD ROM
  • Internet capability to receive updates (Internet capability (needed only for remote support using teamsViewer))
  • Type A USB port, 2.0 or higher for interface box (Must be unrestricted during software install)



    • WARRANTY:

    All telephone support is free. A Three (3) year warranty is included on all parts as well as the computer. Most parts are off the shelf with minor modifications to connections. Warranty is handled on a replacement basis. Just call for over the phone troubleshooting and get an RMA to return the part for replacement. When we receive the bad part, a replacement will be returned the next day. If you are in the continental US, shipping of the new replacement part is covered by us for standard ground delivery. If you require faster delivery, you will be responsible for the shipping cost. No purchase order is required unless you require a new part in advance of us receiving the damaged part. After we receive the part, it will be evaluated. If the problem is a result of misuse, this warranty will not apply and an invoice will issue which would include the details of our findings on the cause of failure.



    SETUP and TRAINING:

    If you are in the Continental US, labor on-site setup and training is included in the price. Actual travel expenses are not included. We would be traveling from Dallas Texas and visit your facility for one day. At that time we will install the software if you supplied your own computer. We would do this through your computer department if they require. Once installed, we will show your operators how the system works and how to set it up to take measurements. All features will be reviewed. Maximum attendance is 6 people. There is a small charge for additional time to train more people. This training will prevent operators from making common mistakes that introduce errors into the measurement, and ensure success.



    SOFTWARE:

    The Runout Installation Software is provided in a folder on the desktop of the computer we supply. It was developed with the new API specification in mind plus additional features described below. Any new releases after your purchase will be available for free on our website. There is NO additional license fee. There is no requirement to install the latest version to get support. New releases will be issued to incorporate new standard features. We welcome suggestions from customers.

    The software that we provide includes standard report types and includes many fields to enter various parameters. There is no limitation of how many computers you can install the software. All data can be viewed and reports can be generated on any computer without requiring the interface hardware or additional license fees. The hardware is only required to take new measurements. Most customers print their reports to a PDF file and rely on that for their final records.



    EDDY PROBE:

    We normally supply a Bently 3300XL series probe and Proximeter. The probe body is a fully threaded with M8, and has the 5mm internal coil. System length is 5 meter. Other configurations are available on request.

    As a no cost option, we would instead supply a Schenck Vibronex (B&K Vibro) probe which is a similar eddy current sensor with some advantages. These are just like the Bently probes except the oscillator/demodulator electronics are inside the sensor making for a much more simple setup. Since the electronics are inside the sensor, there is no requirement for a special calibrated cable and separate proximeter box. If you prefer to use any other eddy probe, then we will provide an adapter cable and discount the price.



    MECHANICAL PROBE:

    An LVDT type probe is used for measuring mechanical runout. The probe tip is interchangeable with any standard type indicator tip having a M2.5x0.45 thread. This probe comes with a Nylon tip so as not to mark your shaft's probe area. The electronics to drive this probe are internal to the interface box. By setting up both probes, the software can show you both the mechanical and electrical run out at the same time for one probe surface. This is displayed graphically with displacement/gap vs angle. Usually these probes are 90 from each other if measurements are taken in V-blocks because they would be setup normal to the V-block surface. The software shifts the trace in the graph so that both traces are in phase.



    PROXIMITY SWITCH:

    A key phasor or proximity switch is used to identify the beginning of each revolution. It can trigger off the key or key way. Setting up the gap is easy with an LED on the sensor. You can set the program to trigger on the leading edge, trailing edge, or center of the key or keyway. The measurement is automatically triggered to start and end based on the triggering of the proximity switch. The software can be configured to account for shafts that have more than one key or keyway.



    ENCODER:

    The encoder is used to monitor the angle during the measurement. This allows the operator to turn the rotor by hand and the plots will still be correct with respect to the angle. That is because acquisition for each measured point in the curve are triggered by the pulses in the encoder. The encoder is provided on a magnetic base and has a pulley on it. The encoder can be driven by a Buna belt, or the pulley can ride tangentially on the surface of the rotor. Since the encoder bracket is spring loaded, it will maintain contact with the rotor.



    OPERATION and LIVE CURSOR:

    Once the probes are setup, the operator starts the program. There is a large display of a bar graph to assist the operator setting the gap of the eddy probe and the center position of the mechanical probe. Then the operator confirms the settings ( number if keyways, direction of rotation, etc). The operator presses a button when ready to take the measurement and then rotates the rotor at will. The machine records the data as it is turned and knows when to start and stop based on the triggering of the prox switch. Data is immediately displayed graphically in a full screen with a large live cursor. As the operator continues to rotate the rotor, the large live cursor moves along the graph indicating the position with respect to the probe. The smaller curser indicates the high spot in the runout. This makes it easy to mark the high spot on the rotor.





    CALIBRATOR:




    Calibration can be done by the end user with the calibrator device. This device is included and shown above. The calibration for ERO can be done for any type of material using a different sample in the device, and each calibration can be stored in the software and and recalled for later use. The micrometer head is designed so that the sample does not rotate when turning the micrometer. The sample just moves axially without rotating and therefor does not introduce any errors during test or calibration. This device can also be used to test and prove the accuracy of the system when measurements are questioned by a witness. The calibrator comes with a ASTM 4140 sample. Printed on the bottom of the calibrator, is a sketch for making samples from different materials.

    This system is very easy to use for measuring bearing journal runout and meets the requirements of API-610. We appreciate your interest and look forward to your order. If you have any questions, you can reach us at (817) 265-6435.
