Condition-Based Maintenance (CBM)
A maintenance strategy that triggers work when an asset’s measured condition crosses a defined threshold — rather than on a fixed schedule.
Definition
Condition-Based Maintenance (CBM) is a strategy that uses real-time or periodic condition measurements — vibration, temperature, oil quality, meter readings — to trigger maintenance only when needed.
CBM vs PM vs PdM
Preventive maintenance (PM) runs on fixed intervals — time or usage. Condition-based maintenance (CBM) runs when a reading crosses a threshold. Predictive maintenance (PdM) extends CBM with models that forecast when the threshold will be crossed.
CBM is deterministic (threshold-triggered); PdM is probabilistic (risk-scored).
How CBM works in FacilityLane
FacilityLane integrates with meters, sensors, and IoT protocols (MQTT, Modbus, BACnet, OPC-UA). When a reading crosses a configured threshold — a vibration spike or a flow rate drop — the system can automatically create a work order, assign a technician, and attach the triggering data.
When CBM makes sense
CBM is best for assets where failure mode shows up in a measurable parameter (bearing wear, oil contamination, differential pressure) and where sensor cost is justified by the cost of unplanned failure. For simple, predictable assets, calendar-based PM remains cheaper.
FAQ
Common questions about Condition-Based Maintenance (CBM).
Not always. CBM can run on manual meter readings — technicians record a value during an inspection round. IoT sensors let you automate the trigger and react faster.
