Charge Mode Accelerometer Portable Calibrator

Calibrate Differential Turbine Accelerometers | Model C9110D

Similar in operation to Portable Vibration Calibrator, Model 9110D, Model C9110D, is a Portable Vibration Calibrator with charge amplifier input. The C9110D supports the calibration of both single-ended and differential charge accelerometers and is supplied with a 7/16-27 2-pin MIL to BNC cable for the calibration of high temperature turbine vibration sensors that have a differential output. Model C9110D is also ideal for calibrating ICP accelerometers, velocity transducers, proximity probes, and piezoresistive sensors over a wide operating frequency and amplitude range.



  • Create Calibration Certificates for Vibration Instrumentation
  • Portable, Lightweight Design with Long Battery Life
  • Low Frequency Operation to 5 Hz
  • Stepped Sine Tests with Pass/Fail Notification After Each Point
  • Differential Charge Accelerometer Connection Cable Supplied


  • In-House Calibration of Vibration Instrumentation
  • Loop Checks & System Troubleshooting
  • Testing Charge Amplifiers Used in Aviation & Energy Applications
  • Proximity Probe Testing & Checks for Mismatched Systems

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. An integral precision quartz reference accelerometer and closed-loop level control gives the C9110D enhanced stability and superior vibration calibration over an extended 5 Hz to 10 kHz frequency range. The device is packaged in a rugged Pelican® Storm case.

CALROUTE firmware allows technicians to program repetitive calibration test points and pass/fail tolerances for both frequency response and linearity. The C9110D creates professional, ISO-17025 compliant calibration certificates that are fully customizable. The C9110D is supplied with an accuracy calibration certificate. Calibration of the C9110D is accredited to the ISO 17025 standard by the American Association of Laboratory Accreditation (A2LA).
