Engineered for cost-effective continuous condition monitoring, this sensor combines our patented integration of Analog Devices’ ADXL358 MEMS technology with standard IEPE signal conditioning to deliver an exceptional performance-to-cost ratio.
It is the ideal solution for online monitoring systems that analyze fundamental vibration parameters, including Velocity RMS, Acceleration RMS, Acceleration true Peak, Kurtosis, Crest Factor and Demodulated Enveloping.

(1) Velocity Spectrum & Velocity RMS: Enables monitoring of unbalance, mechanical looseness, misalignment, and blade pass frequency.
(2) Acceleration & Enveloping Spectrum (with RMS, Kurtosis, Crest Factor): Enables monitoring of lubrication degradation, bearing wear, and gear mesh defects.
(3) True Peak Acceleration (10 kHz - 20 kHz): Enables monitoring of high-frequency phenomena such as cavitation and electrical noise.
Key Advantages Over Piezoelectric Sensors:
For machinery operating at speeds up to 4,000 RPM:
The Rotational Frequency (1X) = 4000 RPM/60 secs = 66 Hz
50th Harmonic Target = 66 Hz x 50 = 3'300 Hz
A maximum frequency of 3,300 Hz falls comfortably within the frequency response of sensors like the Model 405 (0.1 Hz to 4.5kHz)
