The VibraSens PC based automated dynamic pressure calibration system provides calibration of dynamic pressure transducer ranging from charge and voltage type piezoelectric sensors. Test sensor output can be single-ended or differential, ac or dc coupled, isolated or grounded.

With 2 bars (31 PSI) dynamic, our system provides better signal noise ratio at low frequency than pistonphone used to calibrate microphones and other acoustic sensors.

The periodic signal helps us to use digital filtering cross correlation technic that greatly improved signal noise ratio.

Using Computer control, we have also been able to implement comparison calibration with substitution that virtually eliminates uncertainties due to temperature variation and signal conditioner gain on the entire frequency range.

Its operationall software is based on National Instrument Labview to ensure minimum operator error and enhances repeatability.

A new high-temperature cable assembly is ideal for use with differential piezoelectric accelerometers or dynamic pressure transducers usually found in gas turbines.

The cable assembly withstand 260C and interface with a variety of industrial charge-output differential accelerometers having 7/16 27 UNS 2A two-pin threaded connectors.

The model 10.01-D0X-XXX-21 incorporates the VibraSens 600051.01 twisted pair, 316C, differential, low noise treated cable.

The cable is fitted on sensor side with a specifically design connector :

• 7/16 27 UNS 2A thread
• AISI 303 stainless steel
• two high force socket

The other side could be fitted with a 2-pole lemo or any other suitable connector.
