Key takeaways
- A condition monitoring log records vibration, temperature, oil and ultrasonic readings against set alert and alarm limits so faults are caught before failure.
- Each reading is judged against a baseline and an alarm limit, then trended; a rising trend triggers action well before the asset breaks down.
- ISO 17359 sets the general framework for condition monitoring; ISO 10816 and ISO 20816 give vibration severity limits for rotating machinery.
- Condition-based maintenance replaces fixed-interval servicing with action driven by the asset's actual health, cutting both breakdowns and over-servicing.

What is a condition monitoring log?
A condition monitoring log is a structured register used to record periodic health readings taken from rotating and critical plant, so deterioration is detected before it becomes a failure. For each route point it captures the asset and measurement location, the reading type (vibration in mm/s, bearing or winding temperature, oil analysis result, or ultrasonic level in dB), the value measured, the baseline and the alert and alarm limits, the resulting status, the trend against the previous reading and the action taken. It is the evidence trail behind condition-based and predictive maintenance: instead of servicing on a fixed calendar, the team acts on what the machine is actually telling them.
Reliability technicians, maintenance planners and fitters in mining, manufacturing, energy and facilities use this log on pumps, motors, gearboxes, fans, compressors and conveyors. Without it, early-stage faults such as bearing wear, misalignment, imbalance or lubrication breakdown go unseen until the asset trips or seizes, taking production with it. In MapTrack, each reading can be logged against the asset profile on a phone at the measurement point, with alarm limits attached and a history that trends automatically, so a breach raises a work order rather than sitting in a notebook. The practice follows ISO 17359, which sets out the general condition monitoring process, and vibration assessment commonly references the ISO 10816 and ISO 20816 severity bands for rotating machinery.

Benefits of using this condition monitoring log
- Early fault detection: rising vibration, heat or oil debris flags bearing wear, imbalance or misalignment weeks before a breakdown.
- Condition-based servicing: action is driven by measured health, not a fixed calendar, so you avoid both surprise failures and needless strip-downs.
- Trending evidence: readings logged against a baseline show the rate of deterioration, which sharpens the call on when to intervene.
- Clear alarm limits: alert and alarm thresholds on every point remove guesswork and make an out-of-limit reading obvious to anyone on the route.
- Less unplanned downtime: catching a fault while the machine still runs lets you plan the repair into a window instead of reacting to a stoppage.
- Audit and warranty support: a dated reading history demonstrates due diligence and backs warranty or insurance claims on premature failure.
- Smarter spares and labour: knowing a bearing is degrading lets you stage the part and the crew before the asset is down, not after.
Benefits of digitising forms in MapTrack

What to include in a condition monitoring log
This condition monitoring log covers 10 key areas:
- Log details: organisation, plant or area, technician, monitoring route and the date of the round.
- Asset ID and description: the machine and, where relevant, the specific component being monitored.
- Measurement point: the bearing or location on the asset (for example motor drive end, pump non-drive end).
- Reading type and unit: vibration (mm/s RMS), temperature (degrees C), oil analysis result, or ultrasound (dB).
- Measured value: the reading taken at this point on this round.
- Baseline: the known-good reference value for that point when the asset is healthy.
- Alert and alarm limits: the warning and action thresholds the reading is judged against.
- Status: normal, alert or alarm, derived from the value against the limits.
- Trend: stable, rising or falling compared with the previous reading.
- Action and reference: action taken or work order raised, plus instrument or analyst reference.
How to use this condition monitoring log
- Define the monitoring route and the points on each asset before you start collecting readings.: List the critical machines and the exact measurement locations on each one, such as motor and pump bearings, and the reading type for each point. A fixed route makes readings comparable round to round and stops points being missed when a different technician walks it.
- Establish a baseline and set alert and alarm limits for every point.: Record a known-good reading for each point while the asset is running well, then set the alert and alarm thresholds. Use the ISO 10816 or ISO 20816 vibration severity bands for the machine class, or manufacturer figures, so limits are defensible rather than arbitrary.
- Take readings consistently at the set interval with a calibrated instrument.: Collect each reading at the same point, speed and load condition using a calibrated meter, and write down the value, the unit and the date. Consistent conditions matter: a reading taken at a different load is not comparable and can mask or fake a trend.
- Compare each reading against baseline and limits and assign a status.: Judge every value against its baseline and its alert and alarm thresholds, then mark the status as normal, alert or alarm. An alert means watch more closely; an alarm means the point has reached the level where planned action is required before failure.
- Trend the reading against history and decide the action.: Compare the value with previous rounds to see whether the point is stable, rising or falling, because the rate of change often matters more than a single number. Decide the action: continue monitoring, shorten the interval, or raise a work order to investigate or repair.
- Record the action, raise any work order and review the route periodically.: Note the action taken and the work order reference against the breached point, then close the loop once the repair is done and a fresh baseline is taken. Review the route, points and limits periodically as machines, duties and failure history change.

Set the interval by criticality and machine type. High-criticality rotating plant such as main pumps, fans and compressors is commonly monitored monthly, with weekly or continuous monitoring on the most critical units, while lower-risk assets may be quarterly. Any point that reaches alert status should be read more often until it stabilises or is repaired. Oil analysis usually follows its own sampling interval, often quarterly. In MapTrack, readings logged against each asset trend over time and a breached alarm limit can raise a work order automatically, so the route stays driven by machine health rather than a static calendar.
