Reliable Energy Monitoring for Industrial Automation and Electrical Distribution
Multifunction energy meters such as the Finder 7E.85.8.400.0210 measure electrical consumption and power characteristics to help operators understand how energy is used across industrial machinery, production facilities and commercial electrical installations. By monitoring voltage, current, active power, reactive power, apparent power and power factor, the meter provides information that can support energy efficiency improvements, electrical load management and preventative maintenance.
The Finder 7E.85 Series uses external current transformers to measure electrical current without routing the full load current directly through the meter. This arrangement makes the device suitable for monitoring higher-current electrical installations when correctly matched with appropriate CTs. Configurable current transformer settings allow the meter to calculate electrical measurements based on the installed transformer ratio.
The integrated RS485 Modbus RTU communication interface enables electrical measurement data to be transmitted to compatible PLCs, building management systems, supervisory control platforms and energy monitoring software. This supports centralised energy data collection, remote monitoring and analysis of electrical performance across multiple installations.
Its bidirectional energy measurement capability is particularly useful in installations where electricity may flow in both directions, including facilities with on-site generation. The meter records imported and exported energy separately, while harmonic distortion and maximum demand measurements provide additional information for power quality assessment and electrical system optimisation.
