VibraSens Redefines Continuous Machinery Monitoring with Revolutionary Low-Cost IEPE MEMS Sensors

VibraSens, a leading European manufacturer of industrial vibration transducers, announces the launch of its new Model 405 IEPE MEMS Accelerometers. Designed specifically for continuous online monitoring of rotating machinery operating below 4,000 RPM, this new MEMS sensor line shatters traditional cost barriers by delivering high-end dynamic performance at a fraction of the price of conventional piezoelectric transducers.

Breaking the Cost Barrier in Continuous Condition Monitoring

While real time online vibration monitoring has historically been restricted to high-criticality assets due to the high cost of piezoelectric sensors, the Model 405 changes the economics of predictive maintenance.

By combining Analog Devices’ MEMS technology (ADXL358) with VibraSens’ patented IEPE signal conditioning circuit, the new series seamlessly interfaces with standard 4 mA constant-current power supplies, PLCs, DCSs, and portable data collectors—delivering enterprise-grade data at an unmatched price-to-performance ratio.

"Our goal was simple: eliminate the price barrier that prevents plant managers from instrumenting 100% of their balance-of-plant machinery," says Ange Brunner, Managing Director at VibraSens. "With this new IEPE MEMS architecture, we offer piezo-equivalent measurements for machinery operating below 4,000 RPM—complete with near-DC measurement capabilities, zero sensitivity drift, and immunity to ski-slope saturation—at a price point that makes full-plant, real-time online monitoring economically viable."

Superior Technical Capabilities Over Piezoelectric Transducers

In addition to its disruptive pricing and piezo-equivalent performance on machinery operating below 4,000 RPM (matching both dynamic range and electrical noise density), the VibraSens MEMS-IEPE architecture overcomes key physical limitations inherent to traditional dynamic piezoelectric transducers:

  • Unbeatable Cost-to-Performance Ratio: Dramatically reduces the per-channel hardware cost for continuous online monitoring systems tracking Velocity RMS, Acceleration RMS, Kurtosis, Crest Factor, and Demodulated Enveloping.

  • Quasi-Static Low-Frequency Response (500mV/g - 0.1 Hz): Captures ultra-low-frequency vibrations down to 0.1 Hz without phase distortion, enabling early fault detection on slow-rotating machinery (<500 RPM) such as wind turbine main shafts, agitators, and gearboxes.

  • Reduction of "Ski-Slope" Saturation: Featuring a heavily damped axial and transverse resonance with a Quality Factor (Q) 10 times lower than piezoelectric sensors, the sensor prevents amplifier saturation and low-frequency noise artifacts caused by high-acceleration events like pump cavitation.

  • Lifetime Sensitivity Stability: Zero sensitivity drift over time eliminates the need for routine annual recalibration, significantly lowering total cost of ownership (TCO).

  • Instantaneous Boot Time: Offers zero bias settling time upon power-up, making it ideal also for datalogger.

  • Enhanced Shock Resilience: Micro-machined silicon architecture withstands high-impact magnetic mounting shocks without internal circuit breakdown—making it the premier transducer for magnet-mount route measurements.
