Condition monitoring does not need a year-long transformation. Start on assets that fail often, add fit-for-purpose sensors, wire alerts into your CMMS, then scale. This guide gives a concrete 90-day path with standards-aligned practices so engineering and maintenance teams can prove value fast without overhauling architectures.
Assets to start with and failure modes
Begin where downtime hurts and telemetry is easy to capture. Prioritise motors, pumps, gearboxes and conveyors that are critical to throughput. Typical early signals include bearing wear, misalignment, imbalance, lubrication issues, belt slippage and cavitation. These failure modes show up cleanly in vibration, temperature or current traces, which makes them ideal quick wins. Use a ranked list by downtime cost, MTBF and spare availability to choose the first ten assets.
Align your programme with ISO 17359 for how to set up condition monitoring and use ISO 20816 to interpret machine vibration severity bands for in-service equipment. That pairing gives your triage rules an auditable backbone and avoids arbitrary thresholds during the pilot. Keep notes on operating context and speed, since severity zones depend on size and RPM.
Sensors and mounting best practices
Use vibration sensors on bearing housings close to the load path. Prefer rigid studs or high-strength epoxy for permanent mounts and quality magnetic bases for trials. Capture axial, horizontal and vertical axes where possible. Add temperature on housings or windings, motor current signature at the MCC for drive-train issues, and position/speed for conveyors and indexers.
Match sampling to physics. To avoid aliasing, the Nyquist rule applies: your maximum resolvable frequency equals half the sampling rate. In practice, sample at or above twice the highest fault frequency of interest and use anti-alias filtering. Document sensor ranges, mounting torque and cable routing to ensure repeatability.
For brownfield sites, WirelessHART mesh networks help you deploy quickly while keeping batteries alive and communications reliable. Use gateways near electrical rooms and map mesh hops during the survey to verify link margins before scale-out.
Predictive maintenance attempts to detect the onset of a degradation mechanism with the goal of correcting that degradation prior to significant deterioration.

Alerts to work orders workflow
Start with simple logic that your craft team trusts. Define baseline, warning and alarm bands per asset. For rotating machines, map bands to ISO 20816 severity guidance, then add trend rules like rate-of-change to catch emerging faults without spamming. Document who triages what and the expected SLA per alert class.
Integrate alerts with your CMMS so notifications become work orders with asset ID, fault hypothesis, last service date and parts list. DOE guidance shows CMMS capabilities for work order generation, history, inventory and even automatic need-based tasks when paired with control systems. For enterprise-to-shop-floor data handoffs, use the ISA-95 model to keep roles and systems clean.
Cut the noise: two alert levels, one owner, clear SLA.
90-day rollout and ROI
Weeks 1–4
Scope ten assets, install five to ten sensors, capture a baseline under normal loads, and create one page per asset with mounting photos and sensor IDs. Keep the ruleset minimal to build confidence.
Weeks 5–8
Enable alerts to CMMS, pilot triage, refine thresholds and add one corrective job plan per common fault. Track time-to-detect and time-to-repair. DOE data shows well-run predictive maintenance can reduce downtime and maintenance cost while lifting output, which is where your business case lands.
Weeks 9–12
Publish results and scale to the next cell. Quantify ROI with a simple ledger: avoided downtime hours times cost per hour plus parts saved minus sensors, installation and subscription. DOE reports typical savings from predictive maintenance programmes in the 8 to 12 percent range when properly implemented, which you can use as a benchmark while your own data matures.
FAQ
Critical motors, pumps, gearboxes and conveyors with known failure pain and easy sensor access.
Vibration and temperature on bearings, plus motor current signature at the MCC for electrical or mechanical faults.
Use ISO 20816 bands plus trending for context and tie levels to maintenance SLAs in the CMMS.
Yes. WirelessHART mesh is proven for condition monitoring with robust routing through gateways. Validate link quality during the site survey.
