Phantom Series – Wireless Current Sensor EPH-C30 / EPH-C31

Monitor electrical performance safely and efficiently with the Phantom Wireless Current Sensor (EPH-C30 / EPH-C31) from Erbessd Instruments.

This non-intrusive sensor measures single or multi-phase AC current using split-core clamps.  No wiring or power interruption required. Designed to integrate seamlessly into the Phantom wireless condition monitoring system, it provides accurate electrical data that enhances predictive maintenance and energy management.

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.
