Seismic accellerometer power supply question
Seismic accellerometer power supply question
(OP)
Hi,
I have just aquired a seismic accelerometer the requires a constant current power source. The spec for the power supply is 15-30VDC 1-6ma constant current. Here is the data sheet on this sensor. http://www.vibrametrics.com/pdfs/1030.pdf
I'm guessing that this device works by varying the voltage of the constant current power supply as acceleration increases. Am I right? If so, how critical is the quality of the power supply. This sensor will see limited use so I would rather buy a benchtop power supply that can be used for more than just this application. Can you suggest a reasonably inexpensive cc power supply that is suitable for this sensor.
Thanks Ray

Thanks for the info.

100 hours, or you could buy 3 rechargable ones and keep one
on the charger.
