We would like to point out that accelerometers with charge output can also be connected to the iSV1611 preamplifier if a 1/2” to 10-32 thread adapter is used.
In this way, vibration measurements can be realized with the same measurement technology.
Our optional NVH-FFT software is available for carrying out sensor-specific analyses in dB or acceleration in g.
