No. SAM4 hardware installs inside the motor control cabinet, which sits outside the ATEX zone. No sensor enters the hazardous area. No ATEX certification is needed for the monitoring equipment. No confined space entry. No ignition sources near explosive atmospheres. This is the core advantage of cabinet-based ESA monitoring in chemical plants.

Seveso III and COMAH explicitly recognise condition-based maintenance as a valid strategy for monitoring ageing equipment and preventing major accident hazards. SAM4 provides continuous condition data with a documented audit trail: every alert, every maintenance action, every outcome. That documentation directly supports your Safety Management System obligations and OSHA PSM mechanical integrity requirements.

Yes. SAM4 is highly compatible with variable frequency drives. VFDs are increasingly common in chemical production for process control and energy savings. SAM4 monitors VFD-driven motors from the MCC using the same clip-on installation. The cavitation detection on the 200 kW product pump described above was on a VFD-controlled asset.

No. SAM4 complements vibration, it does not replace it. On assets where vibration sensors are already installed and working, ESA adds electrical fault detection, energy data, and process insights that vibration cannot see. On the rest of your fleet, the assets in ATEX zones, corrosive environments, or simply too numerous to justify vibration routes, SAM4 is the primary condition monitoring source. DuPont ran both programmes in parallel.

ESA detects bearing degradation, mechanical imbalance, belt wear, cavitation, coupling faults, motor winding issues, and grid-level electrical faults. It also detects process-induced issues like incorrect operating procedures. It does not detect mechanical seal degradation on pumps, internal valve faults on compressors, or screw element leakage. We state these limitations upfront because honesty about detection boundaries builds more trust than overclaiming.

None. SAM4 builds its own baseline from live electrical measurements starting at installation. Within weeks, it has enough data to detect anomalies. No historical data export, no SCADA integration, and no process historian connection is required to begin. DuPont had their first detection within the initial deployment period.

At $650,000 per hour of unplanned downtime in chemicals, a single avoided production stop can pay for a multi-year deployment. DuPont prevented €1.7M in costs across 15+ detections. A single belt misalignment detection on an exhaust fan avoided €170,000. The payback depends on your downtime cost, fleet size, and current failure rate. We provide a plant assessment that models the expected return for your specific operation.

SAM4 is monitoring-only. It reads electrical signals passively. It has no connection to control systems and cannot send commands to any asset. Data transmits over cellular or a dedicated network, completely separate from the operational network. No IT/OT convergence is required. No DCS integration. No process historian write access.
