Vibration Meter Online
Measure 3-axis mechanical acceleration, compute vibration velocity (RMS mm/s), and evaluate rotating equipment health according to international ISO 10816 severity standards.
What is an Online Vibration Meter?
A vibration meter online is a digital condition monitoring instrument that leverages hardware MEMS accelerometers built into mobile smartphones, tablets, and laptops to measure dynamic vibrations in machinery.
By sampling continuous 3-axis motion data (\(a_x, a_y, a_z\)) and calculating Root-Mean-Square (RMS) vibration velocity in mm/s, this tool benchmarks industrial equipment health against international standards like ISO 10816 and ISO 20816, warning technicians of rotor unbalance, shaft misalignment, or bearing degradation before catastrophic breakdown occurs.
How to Use the Vibration Meter Online
Inspect rotating machines and analyze vibration telemetry in four easy steps.
Position Device
Rest your smartphone flat against the bearing housing or motor casing to ensure firm mechanical coupling.

Governing Vibration Velocity & Severity Equations
The instantaneous vector resultant acceleration a_total(t) from 3-axis orthogonal sensors is:
For a sinusoidal running frequency f, the Root-Mean-Square (RMS) vibration velocity v_RMS in mm/s is derived by integrating acceleration:
The peak-to-peak displacement D_pp in micrometers (µm) is:
Predictive Maintenance (PdM) Applications
Centrifugal Pump & Blower Balancing
Plant mechanics place their smartphone against pump bearing caps to instantly inspect 1X rotational unbalance. By monitoring velocity drops after adding balancing weights, technicians eliminate shaft fatigue and extend mechanical seal life.
HVAC Fan & Compressor Diagnostics
Rooftop air handlers and cooling towers frequently suffer from belt wear and mounting looseness. Routine online vibration checks flag deteriorating bearings before sudden motor burnout damages building ventilation.
Frequently Asked Questions
Modern smartphones and laptops contain internal Micro-Electro-Mechanical Systems (MEMS) 3-axis accelerometers. The HTML5 DeviceMotionEvent API accesses these sensors to measure instantaneous dynamic acceleration (m/s²) along the X, Y, and Z axes.
ISO 10816 is an international standard that classifies mechanical vibration severity for rotating machinery based on RMS vibration velocity (mm/s). It defines four operational health zones: Zone A (Good), Zone B (Acceptable for long-term operation), Zone C (Unsatisfactory for continuous duty), and Zone D (Danger of imminent damage).
Vibration velocity is directly proportional to destructive fatigue stress in rotating machinery across typical running frequencies (10 Hz to 1,000 Hz). Acceleration emphasizes high-frequency gear mesh noise, while displacement emphasizes low-frequency unbalance.
For harmonic motion, peak-to-peak displacement is obtained by double integrating acceleration mathematically: D = a_peak / (2πf)², or in metric units: D (microns) ≈ 1,000 * (√2 * v_RMS) / (πf).
