Easily monitor electrical load and performance with the Phantom Wireless Current Sensor (EPH-C30 / EPH-C31) from Erbessd Instruments.
Designed for accurate, real-time measurement of AC current. Firstly, this compact wireless sensor uses split-core current transformers (CT clamps). It measures power consumption, phase balance, and electrical health — all without rewiring.
Available in single-phase (EPH-C30) or four-phase (EPH-C31) configurations. In addition, it integrates seamlessly into the Phantom wireless condition monitoring ecosystem. Therefore, allowing you to combine electrical, vibration, and temperature data for complete predictive maintenance insights.
Key Features & Benefits
Wireless current measurement – monitor electrical current safely and without running new cables.
Single or four-phase monitoring – choose EPH-C30 for single line or EPH-C31 for up to 4 phases with separate CT clamps.
Wide current range – compatible with 50 A, 100 A, 250 A, and 500 A split-core clamps.
Accurate performance – ±5 % typical accuracy for reliable electrical analysis.
Industrial protocols – communicates via Modbus, OPC UA, and MQTT through the Phantom Gateway for SCADA or IoT integration.
Secure wireless connectivity – Bluetooth BLE 5.0 transmission with encrypted data for reliability and safety.
Battery powered – replaceable AAA batteries deliver up to 12,000 measurements.
Rugged IP67 housing – designed for harsh industrial and outdoor environments.
Easy installation – quick, non-intrusive clamp-on setup; no need to interrupt power.
Fully compatible – integrates with other Phantom vibration, temperature, and speed sensors.
Applications
The Phantom Wireless Current Sensor is ideal for:
Motors, pumps, and compressors – track load fluctuations and power consumption.
Electrical panels and switchboards – monitor phase imbalance, overloads, or circuit health.
HVAC systems – detect motor faults and efficiency loss.
Production and process equipment – measure current draw to identify mechanical or electrical issues.
Predictive maintenance programs – correlate current data with vibration and temperature readings for complete asset monitoring.
