The UMG 96RM range of universal measurement devices can be used to create energy management systems (ISO 50001/EN16001), cost center management or to monitor power quality, among other applications.
Energy data acquisition & load proﬁle
With the help of the UMG 96RM, acquisition of detailed energy data and the load profile becomes a simple task. This is essential for tracking energy efficiency and to avoid overloads in the energy distribution system.
Cost center analysis
It is becoming progressively more important in industry to be able to assign energy costs to particular products. To do this it is desirable to determine energy costs for individual processes and to charge them accordingly. Cost analysis also allows employees to focus on specific cost optimization and conservation of energy.
Energy management systems (ISO 50001/EN 16001) Energy management systems per standard ISO50001/ EN16001 are essential for monitoring continuous improvements in energy efficiency and reduction of costs. The UMG 96RM range of universal measurement devices can play an important role in establishing an effective energy management system.
Transparency of energy supply
A multi-stage and scalable measurement system allows a higher degree of transparency into the energy supply history. Continuous measurement with high resolution meters is the only way that sporadic events can be analyzed and corrective solutions identified.
Power quality monitoring
The UMG 96RM gives indispensable information about inadequate power quality and enables measures to be undertaken to address recurring problems.
This can result in the prevention of production stoppages, significantly longer service life for manufacturing assets leading to improved sustainability and return on investment.
The UMG 96RM is a latest generation measurement instrument from Janitza®. It is intended for measuring, recording and monitoring electrical parameters (True-RMS) in low and medium voltage systems (1 and 3-phase systems with a neutral conductor).
Among the characteristics of this measurement instrument are the compact construction (96×96 mm), LCD backlight and the measurement of harmonic currents and voltages in each conductor.
In order to achieve a sustainable reduction in energy costs, an overview of the energy consumption and the energy flow in the electrical system is first required.
