What We Monitor

If it runs on an AC motor, SAM4 monitors it.

AC induction motors, centrifugal and positive displacement pumps, compressors, fans, conveyors, and many other rotating equipment types — SAM4 monitors the full drivetrain from the electrical cabinet. Over 10,000 assets monitored across 80+ customers and 5 continents. Here's what we cover and what we detect.

Asset types

Every AC-driven rotating asset

SAM4 monitors any asset driven by an AC motor. Current and voltage signatures captured at the motor control cabinet reveal faults across the entire drivetrain — motor, coupling, gearbox, and driven load.

Pumps

Most monitored

Submersible, booster, borehole, process, injection, transfer, and circulation pumps. SAM4 detects bearing degradation, cavitation, blockage, seal wear, imbalance, and efficiency loss — weeks to months before failure.

Compressors

Gas compressors, air compressors, and process compressors — including assets in ATEX/hazardous zones. SAM4 detects bearing wear, valve faults, imbalance, and efficiency degradation without accessing the compressor skid.

Fans & blowers

Ventilation fans, cooling fans, process blowers, and aerators. SAM4 detects imbalance, bearing degradation, belt issues, and process deviations. Critical for maintaining safe atmospheric conditions in enclosed spaces.

Conveyors

Belt conveyors, screw conveyors, and chain conveyors. SAM4 detects bearing degradation, misalignment, belt/chain issues, blockage, and overload conditions. Common in materials handling across mining, pulp, and manufacturing.

Agitators & mixers

Chemical reactors, blending vessels, and mixing tanks. SAM4 detects bearing degradation, seal failure indicators, imbalance from product buildup, and gearbox issues — without opening the vessel or entering the process area.

Electrical submersible pumps (ESPs)

Downhole ESPs in oil & gas production. These assets operate thousands of metres underground and cannot be inspected without pulling the string — a process costing days and hundreds of thousands of dollars. SAM4 detects motor degradation, pump wear, and gas lock from the surface VSD.

Low voltage motors

AC induction motors up to 1kV — the backbone of industrial operations. SAM4 monitors the motor itself plus the entire connected drivetrain, detecting winding faults, bearing degradation, eccentricity, misalignment, and electrical supply issues from the MCC.

Medium voltage motors

AC motors from 1kV to 15kV driving critical process equipment. These high-value assets are expensive to replace and hard to monitor with sensors. SAM4 detects winding insulation degradation, rotor bar faults, partial discharge indicators, and bearing wear — all from the motor control centre.

Transmissions

Gearboxes, couplings, belt drives, and chain drives. SAM4 detects faults across the full mechanical transmission path — from the motor through to the driven equipment — using electrical signature analysis at the MCC.

Archimedes screws

Archimedes screw pumps used in water treatment inlet works and low-head pumping stations. SAM4 detects bearing degradation, trough wear indicators, drive chain faults, and efficiency loss — critical for preventing pollution events.

Canned motor pumps

Sealless pumps where the motor rotor is immersed in the process fluid. Impossible to access with vibration sensors. SAM4 detects bearing degradation, rotor eccentricity, internal recirculation changes, and winding faults — the only practical condition monitoring approach for these assets.

Platform capabilities

What SAM4 delivers — across every asset type

These capabilities apply regardless of equipment type or industry. Every connected asset gets continuous monitoring, AI-driven fault detection, expert validation, and actionable diagnostics.

Asset health scoring

Every asset displays a health score based on continuous electrical signature analysis. Green, amber, red — visible at a glance in the SAM4 dashboard. Drill into any asset for full diagnostic history and trend data.

Fault detection & classification

AI models identify anomalies and classify fault types: bearing degradation, misalignment, imbalance, cavitation, blockage, electrical faults, and process deviations. Over 90% of developing faults detected weeks to months before failure.

Energy optimisation

SAM4 identifies assets operating below their best efficiency point (BEP), oversized motors, and degradation-driven efficiency losses. Customers like Vitens have achieved 7.1% energy efficiency improvement using SAM4 data.

Predictive alerts

Alerts include fault type, severity, affected asset, recommended action, and estimated time to failure. Every alert is validated by a reliability engineer before it reaches your team. No false positives. No noise.

Fleet-level analytics

Aggregate views across sites, asset types, and fault categories. Track trends over time. Identify systemic issues. The asset map gives geographic visibility across your entire operation — from 20 assets to 10,000+.

Expert monitoring service

SAM4 includes a dedicated team of reliability engineers who monitor your fleet, validate every alert, diagnose root causes, and write specific maintenance recommendations. Plus a named customer success manager and quarterly business reviews.
