CHESTER Current
Reduce unplanned downtime and improve OEE by monitoring machine activity through non-invasive current sensing - retrofit any equipment in minutes, not months.
OEE monitoring starter configuration
A practical first package for proving machine utilization, downtime, and energy signals on a representative production cell before scaling across the shop floor.
Included in the first configuration
CHESTER Current gateway
One IP67 CHESTER unit configured for non-invasive current monitoring on up to four machines or circuits.
Split-core current transformers
Clamp-on probes matched to the machine current range, installed without cutting existing wiring.
Connectivity and cloud feed
NB-IoT, LTE-M, or LoRaWAN data delivery into HARDWARIO Cloud, API, or the buyer's OEE dashboard.
Activity logic
Thresholds for run, idle, stop, and anomaly states so teams can calculate availability without a full MES project.
Best-fit projects
- Legacy machines without PLC access
- Pilot OEE projects on one line or cell
- Maintenance teams validating predictive alerts
Buyer output
- Machine run/idle/stop timeline
- Utilization and downtime export
- Anomaly alerts for abnormal current draw
Bring to the call
- How many machines should be monitored first?
- What current ranges and phases are expected?
- Where should the data land: Cloud, API, MES, or BI?

Use Cases
OEE & Machine Utilization
Track actual production time vs. planned time across your shop floor. Identify underutilized machines and bottlenecks without MES integration.
Predictive Maintenance
Monitor current draw patterns to detect bearing wear, motor degradation, and other failure precursors before costly breakdowns.
Energy Consumption Tracking
Measure per-machine energy consumption to identify waste, allocate costs accurately, and meet ESG reporting requirements.
Legacy Equipment Digitization
Add monitoring capability to older machines without PLC access or protocol support - clamp on and start collecting data immediately.
