Resources
IoT Smart Meter EESM37 from Expert Energy solutions for integrating a smart energy plant with emphasis on its modularity and connectivity:
Real-Time Data Collection
The EESM37 performs precise measurements of electrical quantities (voltage, current, power, power factor and frequency, voltage and current harmonics, temperature, phase and current angle, voltage and current sequence, DI and DO) with instant updating via industrial protocols such as Modbus RS-485, Profibus and others.
Flexible Connectivity
The modularity of the system allows fluid communication with the Energy Link platform, using technologies such as:
- LoRa: wide coverage and low consumption;
- 4G: mobile connectivity for decentralized environments;
- Ethernet: highly reliable wired network.
Integration with Intelligent Gateways
Through the GT202 and GT204 gateways, the collected data is processed, encrypted and sent to the cloud, enabling:
- Centralized energy supervision;
- Performance analysis;
- Automated alarms and reports.
Modularity for Any Type of Plant
Whether in industrial, commercial or power generation environments, the EESM37's open and scalable architecture allows the monitoring network to be expanded as the plant needs, without interfering with existing systems.
