Detect wear before it becomes downtime
Predictive maintenance uses continuous vibration measurement to recognise imbalance, misalignment, bearing wear and loose components early. Instead of fixed service intervals or unplanned stops, maintenance is scheduled when the data shows it is needed.
AMCORIS supplies Epson vibration sensors and accelerometers and supports you from sensor selection and evaluation to integration into your monitoring system.
QUICK ANSWER
Vibration sensor or accelerometer?
Machine vibration severity is commonly assessed as RMS vibration velocity in the 10–1000 Hz band (ISO 20816). The Epson M-A342VD10 and M-A542VR10 vibration sensors output velocity and displacement directly as raw, RMS and peak-to-peak values, so the host does not need to integrate acceleration data. For low-frequency structural vibration or when your system processes raw acceleration itself, a low-noise accelerometer such as the M-A352AD10 (0.2 µg/√Hz) is the better choice.
FROM DATA TO DECISION
How vibration monitoring prevents unplanned stops
Most mechanical faults change the vibration signature of a machine long before it fails. Continuous monitoring makes these changes visible, so worn bearings, imbalance or loose mountings are found during operation instead of after a breakdown.
1
Measure
Three-axis vibration at the bearing housing, gearbox or drive.
2
Process
Velocity and displacement as RMS and peak-to-peak values, calculated in the sensor.
3
Trend
Compare against baselines and limits to see changes over weeks and months.
4
Act
Plan maintenance when the trend shows it, not by the calendar.

SENSOR SELECTION
Which Epson sensor for which monitoring task
All sensors measure three axes with a digital interface. Vibration sensors deliver ready-to-use velocity and displacement values; accelerometers deliver raw acceleration for your own signal processing.

Frequently asked questions
What is the difference between predictive and preventive maintenance?
Preventive maintenance follows fixed intervals. Predictive maintenance uses measured condition data, such as vibration, to service a machine when the data shows a developing fault.
Which vibration values matter for machine condition?
Vibration severity of rotating machines is commonly evaluated as RMS vibration velocity in the 10–1000 Hz band according to ISO 20816. For slow-running machines, displacement is often more meaningful because velocity values become small at low frequencies.
Why use a vibration sensor instead of an accelerometer?
Epson vibration sensors calculate velocity and displacement inside the sensor. This reduces processing and data volume on the host. Accelerometers are the right choice when you need raw acceleration for your own FFT or very low-frequency measurement.
Can I test the sensors before ordering?
Yes. Request an Epson evaluation kit from AMCORIS and test the sensor in your own setup. The M-A352AD10 can also be ordered directly in our online shop.
