Measure and monitor rotational speed with precision using the Phantom Wireless Speed Sensor (EPH-S40) from Erbessd Instruments. This advanced Hall-effect sensor measures RPM, shaft speed, or rotational frequency accurately. It works without contact for motors, pumps, turbines, and fans.
Part of the Phantom wireless condition monitoring ecosystem. It integrates seamlessly with other sensors—such as vibration and temperature modules—to give a complete picture of machine performance.
With wireless Bluetooth connectivity, an IP67-rated housing, and an RPM range up to 600,000 RPM, the EPH-S40 delivers powerful, maintenance-free speed monitoring for predictive maintenance and performance diagnostics.
Key Features & Benefits
High-speed measurement – accurately detects shaft speeds up to 600,000 RPM.
Non-contact sensing – uses a Hall-effect magnet to detect rotational speed safely and reliably.
Wireless connectivity – Bluetooth BLE 5.0 transmission to Phantom Gateway for easy setup and data access.
Multi-protocol integration – communicates via Modbus, OPC UA, and MQTT through the Phantom Gateway for industrial connectivity.
Internal temperature sensor – includes built-in temperature monitoring for added diagnostic value.
Rugged IP67 enclosure – designed for industrial environments and outdoor installations.
Battery powered – powered by two AA batteries with long-life operation and standby power mode.
Compact & flexible installation – mount near rotating shafts or coupling surfaces for accurate readings.
Encrypted communication – ensures data integrity and secure wireless transmission.
Applications
The EPH-S40 Wireless Speed Sensor is ideal for:
Motors and generators – monitor rotational speed, load balance, and start/stop cycles.
Pumps, fans, and compressors – detect belt slip, cavitation, or performance deviations.
Turbines and spindles – measure RPM for process optimization and safety.
Production machinery – synchronise speed data with vibration and current readings for advanced analysis.
Predictive maintenance systems – use speed data alongside vibration signatures to diagnose imbalance or misalignment.
