At ELDAC Process Automation, our Power Transducers offer precise measurement and conversion of electrical power into industry-standard signals, enabling industries to monitor and control their energy usage with accuracy. These transducers provide crucial data on power consumption, which is essential for optimizing energy efficiency, improving load balancing, and ensuring the overall reliability of power systems. Our power transducers are designed for seamless integration with various monitoring and control systems, allowing industries to track power usage in real-time, identify inefficiencies, and take corrective action as needed. Built for industrial-scale operations, they offer high reliability and durability, ensuring continuous performance in demanding environments. Whether used in power generation, energy distribution, or industrial automation, ELDAC’s power transducers provide industries with the insight they need to enhance operational efficiency and reduce energy waste.
Power monitoring sensors measure loads and improve performance by providing instantaneous True Power kW or accumulated kWh data. They are simple, reliable and accurate. Digital communications are available in some models. Contact the factory or a local distributor for more information.
