Target Applications & Governing Standards

1 Scopes Configured
Valves & Pressure Control
ISO 10816 ISO 18436
Target Assets / Components:
Turbine Pump DrivesCompressor ShaftsMotor Assemblies
Detectable Defects & Anomalies:
• Shaft Misalignment• Bearing Fatigue• Mechanical Unbalance

Method Limitations & Operational Boundary Conditions

Critical physics limits, thermal envelopes, blind spots, and ASME Sec V / API procedural boundaries for VA.

Level III Procedure Control
Operating Temp Envelope
Standard Envelope-40°C to +120°C (-40°F to 248°F) for accelerometers
High-Temp CapabilityUp to 450°C (842°F) with charge-mode piezoelectric sensors and hardline mineral-insulated cables

Integrated electronics (IEPE/ICP) accelerometers fail above 120°C due to preamplifier thermal breakdown.

Thickness & Dead Zone
Min ThicknessN/A (Dynamic kinematic vibration monitoring)
Max RangeUnlimited machinery frame size
Near-Surface Dead Zone

Requires structural rigidity; mount must not introduce resonance frequencies below 10 kHz

Surface Condition & Couplant
Roughness & PrepSmooth, flat machined spot or tapped threaded mounting stud required for high-frequency analysis (> 5 kHz)
Coating TolerancePaint layers > 0.5 mm damp high-frequency bearing impact spikes (gSE / Demodulation)
Couplant / Media

Silicone grease or beeswax couplant layer beneath magnetic sensor base

Geometry & Orientation
Orientation Sensitivity

Triaxial measurement required: Horizontal, Vertical, and Axial axes must be monitored to distinguish imbalance from misalignment

Clearance:Safe access clearance from rotating shafts, couplings, belts, and cooling fans
Critical Blind Spots
  • •Cannot detect static volumetric defects, corrosion thinning, or flaws in non-rotating equipment
  • •Low-speed machinery (< 60 RPM) generates ultra-low frequency signals masked by sensor baseline noise
False Indication Trap:

Structural resonance and acoustic airborne noise from adjacent machinery misdiagnosed as internal bearing failure

Recommended Cross-Validation
IRView Method

Infrared thermography to correlate mechanical vibration anomalies with hot bearing journals

UTView Method

High-frequency ultrasonic airborne/structure-borne listening for early bearing lubrication breakdown

Level III Code Compliance Directive:ISO 10816 and ISO 18436 require rigid machine baseline calibration and spectral FFT resolution configured to at least 3200 lines.
