31. IIS3DWB KPIs for condition monitoring
31
#1 Wide & Flat measurement bandwidth
#2 Flat freq. response, Sharp out of band roll-off, No aliasing
#3 Low noise levels
#4 Stable thermal behavior over extended temperature range

32. • Frequency response:
• Bandwidth
• frequency response flatness in pass band
• attenuation in stop band (to avoid frequency aliasing)
• Noise density
• Full Scale and number of axis
• Operating temperature range
• Power consumption (for wireless sensor nodes)
• Interface (analog / digital)

33. • The output of the ADC converter is filtered with a digital low pass filter LPF1 to
ensure the intended sensor’s frequency response:

Attenuation >70 dB at
frequencies higher than ODR
6.3kHz
#1 KPI
Wide & Flat measurement
bandwidth 5kHz (6.3kHz
simulated)

34. Noise density
34
#3 KPI
IIS3DWB recalculated velocity resolution in mm/s, with respect to the sensor noise is typically ~0.05
mm/s, which is much better than requirement (1.4 - 2.8 mm/s RMS velocity limit) for medium sized
motors, in rigid support in Zone B of ISO10816-3

35. Sensitivity drift vs temperature
35
#4 KPI
IIS3DWB sensitivity drift over temperature range is negligible. Zero g offset drift over temperature is
not important for a vibrometer (DC component is not interesting)

36. • Analog bottom port single ended microphone with 63dB SNR min and low distortion with AOP of
132dB
• Low power and with ultra flat frequency response: roll off @ 15Hz
MP23ABS1
