Similar in operation to Portable Vibration Calibrator Model 9110D, The Modal Shop’s Portable Vibration Calibrator with Charge Amplifier Input Model C9110D adds the functionality of a 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.

The C9110D creates ISO 17025 compliant calibration reports via ISO 16063-21 methodology for the following vibration sensor types:

• Integrated circuit piezoelectric (ICP^®)
• Differential piezoelectric charge
• Single-ended piezoelectric charge
• Moving coil (i.e. self-generating, voltage output)
• Piezoresistive (external bridge signal conditioner required)
• Proximity probes (eddy current probes)
• Capacitive sensors (external signal conditioner required)
• Modulated current vibration sensors (external signal conditioner required)

 

 

Product Features & Benefits

• Portable, lightweight design with long battery life. The C9110D can be brought to the turbine engine to loop check high temperature differential accelerometers and their monitoring system, troubleshoot, and calibrate.
• Stepped sine programmability with pass/fail notification after each test point
• Sensitivity display easily toggles from pC/g to mV/g for troubleshooting the source of error in a charge mode accelerometer measurement chain
• Direct connection to internal quartz reference accelerometer allows for confirmation of shaker accuracy without return to The Modal Shop for service
