Taking Measurements; Rv Option - PCB Piezotronics IMI SENSORS 640A10 Installation And Operating Manual

Taking Measurements

When reading the current output from the unit, use the following formula to calculate the vibration level:
Measured mA
4.00
8.00
12.0
15.75
20
Measured mA

RV Option

The RV (raw vibration) option includes a 100 mV/g ±20% additional output. The accelerometer frequency range
is 1 Hz-10 kHz, maximum amplitude of 15 g pk. This vibration signal can be used by data collectors or analyzers
to acquire the acceleration signal for further analysis.
