3 AXES VIBRATION AND SHOCK SENSOR •
4÷20 mA Output •
M12x1 connector output •
General features:
These new accelerometers give a single 4 ÷ 20 mA signal proportional to the
vibrations applied to X, Y and Z axes. Since the measurement is made from a very
low frequency, the acceleration due to gravity is not detected, so the measurement
will not be affected by the mounting position.
Depending on the connection polarity (direct or reverse) it's possible to perform the
RMS measurement on the vectorial sum of the acceleration on the three axes X, Y
and Z or the instantaneous value , simply reversing the two connection wires.
On the version VBS... (bump sensor) the highest instantaneous value is held on the
output for one second, allowing analogue value measurement.
For a reliable connection it is recommended to use M12x1 connectors with the
shield of the cable connected to the nut (see section H of the catalogue).
