The 9210D Low Frequency Portable Vibration Calibrator is the world’s first andonly 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 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.
Immediate instrument verification is available via sensitivity display on the brightly lit LCD screen. The test sensor input supplies ICP® power or can be toggled to voltage mode, allowing the unit to calculate sensitivity and create calibration certificates for Eddy current probes and moving coil velocity sensors. ISO 17025-compliant calibration certificates are created via Microsoft® Excel macro for both linearity and frequency response.
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).
Benefits:
- Verify alert and alarm settings on vibration monitoring systems protecting slow speed machinery such as turbines used in hydro power plants
- Create and save ISO 17025-compliant calibration certificates for both linearity and frequency response
- Simulate vibration in velocity, displacement or acceleration scales at actual machine running speeds
- High payload capability allows for calibration of moving coil velocity transducers
- Proximity probe adaptor kit ensures proper cabling and operation of noncontact displacement sensors
