About This Product

Real-Time RPM Measurement with Proximity Sensor Input

Electromed's RPM Indicator range measures rotational speed from 0 to 9999 RPM with ±1 RPM accuracy, using a non-contact proximity sensor that mounts directly next to the gear wheel. Designed for continuous industrial operation, the TC Series accepts input from a magnetic proximity sensor and displays live speed on bright 7-segment LED panels.

With optional 4–20 mA and MODBUS RS485 outputs, these indicators integrate seamlessly into SCADA and PLC-based automation systems. Available from a compact 0.5-inch DIN panel variant to a 4-inch jumbo wall display, the range covers all workshop floor sizes and visibility requirements.
