Energy monitoring and fault analysis – Measurement case with OPC UA and cloud interface
Delphin Technology AG now offer a new measurement case based on the high-speed Expert Logger series with an integrated OPC UA interface. The measurement case combines two important applications to make it a highly practical device for many manufacturing operations. On the one hand, the measurement case is able to acquire energy consumption data, perform accounting tasks and store data; on the other, it can be used to analyse faults in machines and process signals. The mobile measurement case is available in a range of different configurations.
For energy monitoring applications, the case can be equipped with up to 3 independent measurement circuits to measure power. This enables the energy consumption of several machines to undergo simultaneous accounting. Depending on customer requirements, power measurement units can be used to record real, reactive, and apparent power, as well as voltages, currents and power factors (cos phi). Current/voltage converters can also be used to acquire peak values or to analyse networks for diagnosis purposes. The case has eight synchronous digital/frequency inputs for acquiring energy-meter or flow readings. Electrical connection is via pluggable screw terminals or special connectors according to specific customer requirements.
The case also offers up to 46 analogue inputs and 48 digital inputs for fault analysis. Sampling rates range from 20 µsec up to hours – or daily average rates.
All measurement data and energy consumption information can be independently stored within the measurement case. An internal data storage capability offers space for up to approximately 500 million measurement values including high-precision time stamping. The case is also equipped with an OPC UA interface and can transfer measurement data directly to the cloud. The extensive ProfiSignal Go software is included in delivery. This software enables evaluation using a range of different diagrams portraying data from a µsec resolution up to annual overviews.
Expert Logger 400 – Data acquisition and test stand automation using an OPC UA interface
Delphin Technology AG has extended its Expert Logger range with the new type 400 model equipped with an OPC UA Client/Server interface. This enhancement to the independently functioning data logger system ideally equips it for the universal exchange of measurement data at field level and for the requirements of Industry 4.0. The Expert Logger device is also equipped with ProfiBus, ModBus, CAN-Bus and serial interfaces. PCs are connected via USB, LAN, WLAN and LTE.
The new type 400 is equipped with 16 universally usable, differential analog inputs for measuring mV and mA signals or any type of thermocouple. 24-bit precision and a maximum rate of 1000 measurements per second meets the highest demands required from a data logger. The new Expert Logger also has the option of measuring Pt100(0) sensors using 2, 3 or 4 wire technology or DMS. The device has a total of 24 switchable digital inputs/outputs which can record edge and fault events at microsecond precision as well as output alerts. A total of six analog outputs enable the operation of regulating and control elements.
The Expert Logger series offer a range of model types with 16 to 46 analog inputs which are ideal for independent data acquisition and test stand automation. Monitoring functions can also be performed independently within the device. Measurement data and limit value violations can be immediately transmitted to subsystems via OPC UA. The OPC UA interface also offers data exchange to PLC systems and connecting to PLT systems.
Furthermore, the ProfiSignal Go software – for portraying and analysing measurement data online and offline – remains a fixed element of every Expert Logger device.
Energy management systems using ProfiSignal - now ISO 50001 compliant
Requirements from DIN EN ISO 50001 and obligations for energy audits are forcing many companies into hasty action. Energy consumption in the different areas needs to be acquired, analysed, optimised and then continuously monitored. Delphin's ProfiSignal software is particularly suited to such tasks. ProfiSignal is compatible with Delphin measurement devices but also with many other power-measurement and metering systems available on the market.
The German Federal Office of Economics and Export Control (BAFA) recently confirmed that ProfiSignal is ISO 50001 compliant. For our customers, this means that the cost of the software, as part of an energy management system, is eligible to grants so that reimbursements can be applied for.
We wish to bring to your attention that our software as well as our hardware are ideal for operational energy-efficiency measurement and analysis. For many years we have been providing systems to record and monitor energy consumption data as well as process measurement data. Delphin systems are especially strong in this area. They are able to simultaneously record energy consumption, flow rates and production measurement data such as air pressure, temperatures etc. For example, Delphin systems are monitoring more than 1000 measurement and energy meters in a major German printers, as well as the entire energy consumption in a titanium production facility, and energy data for all cost centres in a large electronics company.
Our mobile energy measurement case systems and stationary switch cabinet systems – both using Delphin hardware and software – identify and analyse potential energy savings and immediately provide users with practical information. ProfiSignal software can be used to generate clear visualisation functions which enable both easy operation and system auditing.
We provide you with advice and support, based on our many years of experience, to develop an energy management system tailored to your requirements. Our support extends from project planning through to system installation and training. Delphin provides you with all the services you require from a single source.
Expert Logger – the latest generation of stand alone data loggers
With its Expert Logger, Delphin Technology AG introduces a new generation of data loggers thatcombine the latest communication technology with advanced measurement technology. The deviceis being launched in three versions, capable of processing 16, 32 or 46 analog input channels. Upto 8 digital inputs/outputs and one SDI12 interface are also available depending on the version.
The main areas of application include product testing, environmental measurement technology,laboratory data acquisition, research and development, and trials and testing.All analog inputs are galvanically isolated from each other. A 24-bit A/D converter ensures fast,precision sampling rates of up to 50 measurements per second per channel. The devices aremaintenance and noise free due to the absence of electromechanical components (such as relays) that are prone to wear and tear.
All Expert Loggers are equipped with internal 4 GB memories that can independently store up to100 million measurement values with date and time stamps. Storage capacity can be extended asrequired via external USB or LAN storage (NAS). Online measurement data or the contents of thedata memory can be transmitted to the internet via an integrated WLAN or UMTS module.
The Expert Logger is also equipped with an energy-saving “sleep function“ for automated switchingoff during breaks in measuring. Independent operation is possible using batteries, rechargeables or solar panels. The Expert Logger can communicate as standard via CanBus, ModBus and ProfiBus. Internal software channels such as calculation channels, limit values and integrators enable online evaluation of measurements and the logging of meaningful data.
Users can quickly and effectively operate the Expert Logger using the powerful ProfiSignal Go software that is included free in delivery. ProfiSignal Go can be used to portray measurement data in trends and to carry out detailed analyses. The software also enables fast ASCII exporting of measurement data for MS Excel™ or for conversion into TDM format.
