Low Frequency Portable Vibration Calibrator with Sensitivity Display

Reduce Risk with Calibration Certificates | Model 9210D

The 9210D Low Frequency Portable Vibration Calibrator is the world’s first and only ISO 17025-accredited, NIST-traceable portable vibration calibrator capable of creating calibration certificates for critical instrumentation used to protect slow speed rotating equipment. Until now, technicians were required to remove moving coil velocity sensors, low frequency accelerometers and proximity probes during an outage and send these instruments to a separate lab for calibration. Battery-powered, rugged and portable, the Model 9210D brings low frequency calibration to the plant floor, allowing users to verify all aspects of their measurement chain, confirm correct operation of critical alarm thresholds, and create a printable, traceable calibration records.

An internal high-resolution quartz reference accelerometer provides unparalleled accuracy while the rugged carbon fiber composite armature supports heavy payloads. A durable Pelican® Storm Case and long battery life make it ideal for use on the plant floor. Closed-loop control shortens calibration time. The 9210D can be scaled in displacement, velocity or acceleration (metric or English units) with 0.7 Hz to 2 kHz frequency range (42 to 120 000 CPM).

The 9210D’s rugged design and payload capability simulates vibration at speeds as low as 42 CPM (0.7 Hz) and supports the creation of ISO 17025 compliant calibration certificates for:

  • Industrial and seismic accelerometers
  • Eddy current probes (proximity probes)
  • Moving coil vibration sensors
  • High-temperature charge-mode vibration systems

The lightweight and portable design also supports in-situ verification of:

  • 4-20 mA loop velocity vibration transmitters
  • Condition monitoring system, PLC, DCS and SCADA system alarms
  • Portable vibration meters and analyzers


Portable Vibration Calibrator Return on Investment

  • Reduced Business Interruption Insurance Risk. Calibration 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 & confidence. Often false vibration alarm trips are just as costly as late tripsOperations 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.
