B&K Deltatron 4396 and 4519 Accelerometers on NI9234

[Suglob_Artur]

Hello,

I've got B&K Deltatron 4396 and 4519 Accelerometers. They have pre-installed charge converter 2646. Data sheet says that they must have 2...20 mA constant current supply. If I use NI 9234, I'll have IEPE excitation current 2,0...2,1 mA. Is it the currrent that I need for correct work of the sensor? If I understood correctly, I could work with 9234 direct, right?

Thanks for help,

Best regards

Hi Suglob_Artur,

I did have a look  at the followng documents:

Product Data: Piezoelectric Accelerometer Miniature DeltaTron® Accelerometers - Types 4519, 4519-001, 4519-002 and 4519-003 (bp2071)
https://www.bksv.com/media/doc/Bp2071.pdf

Product Data Sheet: Piezoelectric DeltaShear® Accelerometers, Uni-Gain® , DeltaTron® and Special Types
http://www.discom.de/documentation/English/Sensoric/BuKSensor.pdf

and both Sensors seem to have a Constant Current Supply of +2 to +20mA.

The 9234 can provide the 2mA.

Have a look at the general description of IEPE:

IEPE Standard
http://www.mmf.de/iepe_standard.htm

and try out the example I took from the DAQmx Examples. I tested it with 9234, and it should work.

Cheers, Niko
