THERMAL MAPPING & IR DIAGNOSTICS
PREDICTIVE INFRARED SCANNING
Infrared signatures allow us to "see" friction and electrical resistance before they manifest as mechanical failure or fire hazards.
POINT A:
BEARINGS
< 60°C
POINT B:
STATOR CORE
< 85°C
PRIORITY TARGETS
- Electrical terminal box connections (Loose bolts)
- HPU Solenoid coils (Stiction/Internal leakage)
- Excitation transformer core (Saturation)
EMISSIVITY (ε) CALIBRATION
PAINTED
METAL
0.95
OXIDIZED
STEEL
0.85
POLISHED
SHAFT
0.20
THE BLACK TAPE METHOD: For shiny shafts, apply a piece of black electrical tape (ε=0.95), wait 5 mins, and measure the tape surface instead of the bare metal for accurate results.
