Description

The Essential IEPE MEMS Sensor for Continuous Online Vibration Monitoring (Machine<4,000 RPM)

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:

Damped Axial & Transverse Resonance: Prevents sensor saturation during high-impact transients (e.g., cavitation). Resonant Quality factor ( $Q$ ) is $10\times$ lower than piezoelectric elements, eliminating low-frequency "ski-slope" noise distortion.
Lifetime Sensitivity Stability: Zero sensitivity drift over time, eliminating frequent recalibration.
Quasi-Static Response: Measures near-DC (0 Hz) signals impossible with traditional dynamic piezo elements.
Superior Saturation Recovery: Rapid recovery from mechanical overloads without low-frequency "ski-slope" noise distortion.
Compact & Shock-Resilient: Highly resilient micro-machined architecture is perfectly suited for magnet mounting. Piezo sensors electronic fail after few shocks.
Instantaneous Measurement: Zero warm-up or settling time upon power-up.
