Product Support Included with Purchase

  • NIST Traceable Certificate of Calibration, Accredited to ISO 17025 by A2LA
  • USB Flash Memory Drive: Loaded with CALROUTE Workbook
  • Quickstart Guide Available in English, Chinese, Japanese, Polish, & Russian
  • 2-Year Warranty, Inclusive of Drift/Accuracy
  • Technical Training Webinars Available Upon Request, 24/7 Video Library

New CALROUTE firmware allows technicians to program repetitive test points such as alert and shutdown thresholds at machine running speed. Once programmed via supplied Microsoft Excel® CALROUTE Generation Workbook, the Instrumentation and Controls personnel can test system linearity, accuracy, and shutdown logic in seconds. No additional software is needed.

The Model 9100D mechanically simulates vibration in acceleration, velocity, and displacement in both English and metric scales, running on battery power for up to 18 hours. Vibration is controlled via the internal reference accelerometer, eliminating the need for technicians to manually enter the payload of the sensor under test.

Benefits of Field Testing

  • Reduced Business Interruption Insurance Risk: Calibration, vibration sensor validation, and confirmation of alarms in the vibration protection system are part of the recommended best practices issued by risk engineers representing the world’s primary insurance underwriters. Checks, certifications and audits of the condition monitoring system – like a well maintained fire protection system - make the plant more desirable in a potentially tough insurance market.
  • Cost Savings: Save the maintenance budget, validate old sensors instead of throwing them away. With no moving parts, piezoelectric instrumentation and proximity probes can generate reliable output for years. Too often these sensors are deemed disposable, tossed away and replaced on an annual basis.
  • Promote Safety: Catastrophic machinery failures have dangerous consequences. The vibration protection system is often the last line of defense. Simulating vibration faults and testing the system ensures your teammates are safe on the job.
  • Reduce Downtime: Machinery failure without warning becomes a thing of the past with a field tested vibration protection system.
  • Peace of Mind: When that $1 million asset begins to fail, will you get a critical text to your cell phone from the monitoring system? The calibrator is a low cost insurance policy against vibration protection system failure. Simulating vibration faults at various running speeds allows reliability managers to ensure they will.
  • Improve Personnel Efficiency: Stop “chasing ghosts.” Checking nuisance vibration trips with a portable shaker table identifies cabling faults, scaling errors, programming errors and sensor sensitivity shift allowing analysts to focus the real goal: uptime.
  • Strengthen departmental relationships and confidence: Often false vibration alarm trips are just as costly as late trips. Operations department scoffs as reliability struggles to explain the shutdown to management. Confidence in the system erodes quickly and costs time and money. Field verification promotes confidence and uncovers system errors.

Whether your goal is vibration monitoring loop checking, proximity probe calibration, accelerometer calibration, 4-20 mA transmitter validation, or other vibration system checks, the Model 9100D Portable Shaker Table, a mobile vibration shaker from The Modal Shop, can help promote safety, improve efficiency, and maintain peace of mind.

With an integral, precision quartz reference accelerometer, the shaker table is built with robust carbon fiber composite armature flexure supports, capable of simulating vibration on payloads up to 800 grams. The unit allows calibrations over a frequency range of 5 Hz to 10 kHz, and closed-loop level control makes the shaker much easier to use than other portable field calibrators. Direct BNC connection to the reference accelerometer allows users to check the integrity of the shaker and reference. The device is supplied with an A2LA accredited calibration certificate.
