Secondary Device Functions (continued)
The objective of this function is the detection of larger
vibration deviations that arise between normal and
abnormal operation as well as the detection of trends
(change of the values over time).
The accuracy of the measurement is limited by the
application, because the device is mounted to perform the
primary function (e.g., optical distance measurement) and
not as a sensor for vibration measurement. Thus, not only
are the vibrations of the vibration source that is to be
measured, but also the vibrations of the entire mechanical
system.

This function is based on the ISO-10816-3 standard, but
for a detailed vibration analysis Balluff offers special
sensors.
The product family is designed such that it offers complete
monitoring functionality, whereby the status monitoring is
the primary function of the sensor and it is mounted on the
object or on the machine.
