  • Performs end-to-end measurement chain checks
  • Extensive 18 hour battery life
  • Maximum sensor payload of 800 grams
  • Lightweight unit is only 18 lbs
Portable Vibration Calibrator

Industrial Portable Vibration Calibrator - 699A07

Model 699A07 Portable Vibration Calibrator is an ideal tool for checking accelerometers, velocity transducers and proximity probes over a wide operating frequency and amplitude range. The unit is a compact, battery-powered, and completely self-contained vibration reference source which can be conveniently used to calibrate individual sensors, vibration switches and data collectors, as well as to validate the entire measurement channel of a condition monitoring or recording system.

  • Calibrate from 7 Hz to 10 kHz (420 to 600 000 CPM)
  • Check alarm & alert trip points in condition monitoring systems
  • Internal memory and USB flash drive output
  • Digital closed-loop control for enhanced stability and accuracy
  • Generate calibration certificates that are ISO 17025 compliant

Low Frequency Portable Shaker Table

Low Frequency Portable Shaker Table - 9200D
(Learn more on www.modalshop.com)

The 9200D Low Frequency Portable Shaker Table is designed for verifying critical vibration instrumentation used to protect slow speed rotating equipment as low as 0.7 Hz (42 CPM). 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 9200D brings low frequency calibration to the plant floor.

  • Calibrate from 0.7 Hz to 2 kHz (42 to 120 000 CPM)
  • Long lasting 14 hour battery life
  • Rugged, lightweight design is ideal for industrial applications
  • Closed loop control reduces testing time
  • Confirms entire measurement channel: sensor, cabling, signal conditioning and data acquisition systems
