CG Emotron M20 Shaft Power Monitor with CTM050 ⚙️🔌 | Motor Load Monitoring up to 50A for Pumps, Mixers & Conveyors

The CG Emotron M20 Shaft Power Monitor with CTM050 is a robust, industrial-grade solution designed to detect early signs of equipment issues by monitoring motor shaft power output in real time. 💡 This intelligent device prevents costly failures due to dry-running, cavitation, overload, or mechanical blockages in motor-driven systems. 🛑🔧

The CTM050 Current Transformer extends monitoring capability to motors drawing up to 50 Amps, making it perfect for medium-to-heavy-duty industrial machines like pumps, mixers, crushers, conveyors, and fans. 🌀📦

By using your motor as its own sensor, the M20 eliminates the need for external load sensors, minimizing installation costs while boosting accuracy and reliability.

Why Buy the CG Emotron M20 Shaft Power Monitor with CTM050 from Stockhai?

Stockhai supplies genuine CG Emotron shaft power monitors backed by manufacturer warranty, technical support, and pan-India shipping. Preventing unplanned downtime from cavitation or dry-running is far cheaper than replacing a burnt-out motor or pump, so the M20 typically pays for itself after preventing just one failure. Every unit is tested before dispatch and ships with installation guidance for panel builders, OEMs, and maintenance teams.

Frequently Asked Questions

What does the CTM050 current transformer do? It allows the M20 relay to monitor motors drawing up to 50 A, extending the standard monitoring range for medium to heavy duty loads.

Does the M20 need external load sensors? No, it uses the motor itself as the sensor, reading shaft power directly from voltage and current, so no separate torque or pressure sensors are required.

Is the CG Emotron M20 Shaft Power Monitor with CTM050 suitable for retrofitting? Yes, its compact DIN rail design and 3 second auto set feature make it easy to retrofit onto existing pumps, mixers, and conveyors without rewiring the motor circuit.
