Portable vibration calibrator brings lab accuracy to the field
13 April 2013
PCB Piezotronics has introduced an intelligent portable vibration calibrator that brings laboratory accuracy to field testing applications.
The new 9110D portable vibration calibrator is suitable for checking accelerometers, velocity transducers and proximity probes over a wide operating frequency and amplitude range.
The instrument is a compact, battery-powered and completely self-contained vibration reference source that calibrates individual sensors, vibration switches and data collectors as well as validating the entire measurement channel of a condition monitoring or recording system.
An integral precision quartz reference accelerometer and closed-loop level control give the 9110D enhanced stability and superior vibration calibration over an extended 7Hz to 10kHz frequency range. Traceable calibration of accelerometers is per ISO 16063-21.
Entirely self-contained and packaged in a rugged Pelican Storm case, the 9110D is always ready for travel to test sites.
Additional features include an ICP or voltage test sensor input for direct connection and readout of the most common types of accelerometers and velocity transducers.
The test sensor sensitivity is calculated and displayed on the screen in real-time and the unit’s internal memory can store up to 500 calibration records with up to 30 data points per record.
These can be transferred to a computer simply by using a USB flash drive allowing for creation and printing of ISO 17025-compliant customisable certificates and reports using the supplied Excel worksheet template.
Alongside its new 9110D, PCB Piezotronics also offers a more basic model the 9100D which now features two BNC connections – one for an external oscillator input and the other for the output of the reference sensor.
Featuring a simplified user interface comprising just two dials to set frequency and amplitude, the 9100D greatly improves control and usability compared with the previous generation model 9100C.
PCB Piezotronics’ new 9110D/9100D portable vibration calibrators join the company’s extensive family of calibration products and systems.
These include the model 394C06 handheld shaker, model 9155D accelerometer calibration workstation that now has ultra-low frequency options with a SmartStroke long stroke shaker allowing sufficient excitation for a useable frequency range as low as 0.1Hz.
PCB Piezotronics also offers a PneuShockTM shock calibration workstation, model K9525C featuring an ICP reference accelerometer (PCB model 301A12) for calibrations according to ISO 16063-22.
