New mobile energy-measurement case
Delphin Technology AG has developed a mobile energy-measurement case for acquiring and processing energy measurement data. The measurement case is able to acquire digital impulses from electricity, gas and water meters. It has an integrated 3-phase power measuring unit for measuring the electrical power from motors, pumps, drives etc. Energy data from PLC or control systems can also be acquired via field bus interfaces such as PROFIBUS or ModBus.
The mobile device will benefit those users tasked with analysing or recording energy data as well as service providers commissioned by clients to carry out energy measurements.
The energy-measurement case is configured via LAN and can then function independently – thanks to its integrated data memory capable of storing several million measurement values. The case can be equipped with a UMTS-modem to enable wireless operation.
An option is also available for using high-speed analog inputs enabling process analysis from raw energy measurement data. High-speed analog inputs also enable network analysis and the detection of faults or peak levels.
The case can be supplied with Rogowski coils so that power and current data can be acquired non-invasively.
Online and offline analysis of the energy data is performed using the ProfiSignal Go software which portrays data as a y(t) diagram. The logic-analysis diagram is capable of displaying each measured impulse with faults being easy to identify.
