Bearing regions
Trend comparable housing regions after the machine reaches a stable operating state.
IR thermography
Turn thermal images into component-level trends.
ConditionCore maps documented machine regions such as the motor drive end, non-drive end, coupling, gearbox housing and pump bearing, then compares like-for-like temperatures across time and operating state.
IR thermography
Temperature change needs a controlled comparison.
Keep the same physical region, surface assumptions and operating state attached.

- View, emissivity, reflected temperature and load

- Comparable surface-temperature change
Illustrative thermal workflow
Illustrative · not a customer resultCompare the same physical region under matched conditions.
A documented region of interest (ROI) keeps each surface-temperature estimate attached to the same machine location; it does not turn heat into a diagnosis.
View same inspection positionLoad 81 to 82%Stability 45 to 46 minEmissivity basis documented
Motor drive end58.0 °C → 59.1 °C
Gearbox input housing61.2 °C → 70.8 °C
Driven-end housing54.7 °C → 55.3 °C
The gearbox-input region changes more than the other illustrated regions. A thermal camera estimates surface temperature; housing temperature is not internal bearing temperature, and the change does not identify its heat source by itself.
Data in
The context required for comparison.
A thermal camera estimates surface temperature; housing temperature is not internal bearing temperature. A hot region is evidence of change, not a standalone fault diagnosis.
- Radiometric thermal images
- Emissivity and reflected apparent temperature
- Distance and viewing angle
- Ambient conditions
- Machine load and speed
- Thermal stabilization time
What it can reveal
What the measurement can support.
Motor regions
Separate drive-end, non-drive-end and body temperatures instead of averaging the frame.
Gearbox housings
Compare like-for-like regions while retaining load, lubricant and ambient context.
Couplings and guards
Use geometry and view history to distinguish the target from transferred heat.
Cooling performance
Identify changing temperature distribution that may indicate restricted heat rejection.
Electrical regions
Surface abnormal thermal patterns for qualified electrical follow-up where applicable.
How ConditionCore uses it
From source data to a qualified observation.
Motor and bearing regions, cooling loss and abnormal heating, compared only across qualified like-for-like views.
Map
Attach documented regions of interest to the correct machine component and inspection view.
Qualify
Retain emissivity, reflected apparent temperature, viewing geometry, ambient conditions and load.
Trend
Compare the same component region under sufficiently similar operating conditions.
Correlate
Test whether the thermal change supports or challenges the leading machine hypothesis.
Common questions
IR thermography, in practice.
See the controls required for a trustworthy comparison.
What can IR thermography detect on industrial machines?
IR thermography can reveal abnormal thermal patterns associated with friction, load, cooling, lubrication or electrical conditions. It does not determine the root cause without suitable context and corroboration.
How does region mapping improve thermal trending?
Region mapping keeps each temperature attached to the same physical area, such as a motor drive-end housing, so comparisons do not mix unrelated parts of the image.
What information is needed to compare thermal images accurately?
Useful comparisons retain emissivity, reflected apparent temperature, distance, angle, ambient conditions, machine load and time to thermal stability wherever available.
