Siemens measuring devices to capture energy data with higher accuracy

Siemens Smart Infrastructure has added the 7KM PAC3220 and 7KM PAC3120 measuring devices to its Sentron power monitoring portfolio.

These devices capture energy and system data from buildings, infrastructure and industrial facilities and transfer them via standard communication protocols to higher-level energy management, automation and IoT systems.

This data can then be used to identify energy hogs, detect system malfunctions as early as possible and proactively prevent downtimes. This allows companies to sustainably boost their energy efficiency and system availability. The new devices offer higher accuracy than the previous models and have a new design.

New measuring devices from Siemens capture energy data with higher accuracy
The new 7KM PAC 3220 devices are designed for sophisticated energy management operations in industrial environments.

They can be used in any 50 Hertz (Hz) and 60 Hz grids and measure electrical parameters such as voltage, phase current and frequency as well as active, reactive and apparent power.

In addition to instantaneous values, the devices also store precise mean values for periods between 10 seconds and 15 minutes. Standard communications protocols such as Modbus TCP, Profibus or Profinet can be used to transfer the data to higher-level systems. New features include a color LED display on the device and an integrated web interface allowing measurements to be displayed in a browser.

The 7KM PAC 3120 devices offer an easy and cost-effective way to get started with power monitoring in buildings and infrastructures, such as office buildings or data centers. They record energy consumption and basic values such as current, voltage and power. The Modbus RTU communication protocol can be used for data transfer.

When combined with the Sentron powermanager analytics software, the 7KM PAC series measuring devices form a complete and easy to implement power monitoring system, which captures and analyzes energy values from infeed to individual loads. The devices are certified according to International Electrotechnical Commission (IEC) and Underwriters Laboratories (UL) standards and can be used worldwide. The measuring devices are easy to install in existing power distribution systems.
