Product Info

🌟 Key Takeaways
- Proper measurement points influence diagnostic accuracy by more than 50%.
- 1332B supports Velocity and Acceleration for fault separation.
- Capturing 3-axis vibration improves diagnostic clarity.
- DE / NDE / Bearing Housing must be measured every inspection.
- ISO10816 helps define advanced alarm thresholds.

ーーーーーーーーーーーーーーーーーーーーーーーーーーー

Many technicians measure vibration at only one point, leading to misinterpretation.
For example, bearing degradation may be missed because the selected point does not receive the actual vibration energy.
Accurate measurement point selection is the foundation of reliable predictive maintenance.

■　1) Primary Measurement Points on a Compressor
A) Motor Drive End (DE)
Receives direct force from the coupling or belt.
- Ideal for detecting unbalance and misalignment
- Use Velocity to observe overall machine vibration

B) Motor Non-Drive End (NDE)
Used to compare against DE.
- DE high alone → unbalance
- DE & NDE both high → misalignment

C) Bearing Housing
Most critical point for bearing inspection.
- Use Acceleration Peak
- Detect high-frequency impacts from rolling elements

D) Compressor Block / Frame
Used to detect looseness and resonance.
- Measure multiple spots to locate structural vibration peaks

■　2) Three Essential Measurement Directions
Each measurement point should be captured in:
- Horizontal
- Vertical
- Axial

Interpretation examples:
- High Axial → misalignment
- High Horizontal → looseness
- High Vertical → unbalance

■　3) Sensor Mounting for Best Signal Quality
1332B supports several mounting methods:
- Magnet mounting — highest stability
- Contact pin — for hard-to-reach areas
- Adhesive mounting — for small parts or temporary setups

Principles:
- Use magnet when high resolution is required
- Avoid handheld measurement due to noise
- Ensure firm contact to maintain measurement repeatability

■　4) Using ISO10816 for Advanced Threshold Definition
After gathering multi-point data:
- Zone A = Good
- Zone B = Acceptable
- Zone C = Risky
- Zone D = Unsafe

Monthly data helps form a baseline and vibration trend for fault prediction.

■　Insight Bridge
With correct measurement points and axis data, users can shift from simple fault detection to predictive failure forecasting—an essential goal of advanced PdM.
