Technical characteristics
of the sensors
Apart from vibrations, both sensors also always measure
temperature as a characteristic value.
Sensor KPIs measured The following characteristic values (KPIs) are determined:
■
RMS
low
RMS value of acceleration
⬍
750 Hz
■
RMS
high
RMS value of acceleration
⬎
750 Hz
■
Kurtosis
low
Kurtosis of acceleration
⬍
750 Hz
■
Kurtosis
high
Kurtosis of acceleration
⬎
750 Hz
■
ISO
velocity
RMS value of velocity 2 Hz to 1000 Hz
■
DeMod
RMS value of demodulation curve, HP 750 Hz
■
Temperature.
Sensor battery service life The battery service life depends on various parameters and
operating conditions:
■
ambient temperature
■
quality of wireless connection
■
number of wireless connections to downstream sensors
■
frequency of measuring intervals
■
manual activation of individual measurements.
The calculated sensor service life for both types of sensor
at the pre-set measuring intervals is 5 years.
