Expert Logger data logger: explanation, application and advantages

The Expert Logger enables reliable data acquisition and processing with versatile interfaces for a wide range of applications. In the following, not only the basics, the application and the advantages of the versatile data logger are highlighted, but also reference is made to in-depth questions: from interfaces and sensors to sampling rates.

1. What is an Expert Logger?
   
   Expert Logger is a compact, high-performance data logger for the automatic and fail-safe recording and storage of measurement data. It is a data logger of the latest generation that combines state-of-the-art communication with sophisticated measurement technology. Thanks to its FPGA technology, the logger processes up to 46 analog input channels at variable sampling rates. It supports a large number of sensors, stores the measurement data in the device in a fail-safe manner and transmits the precisely recorded measurement values autonomously via USB or LAN to the Internet or to a PC for evaluation.
   
   
2. How does data logging with Expert Logger work?
   
   Expert Logger records data from a wide variety of sources. These include sensors that output standard signals such as 4-20 mA or 0-10 volts, as well as field devices that communicate via protocols such as Modbus TCP/RTU or OPC UA. This data is processed and stored in the data logger's internal memory. The data can already be pre-processed and offset against each other in the device, completely independently of the PC. In addition, the recorded data can be accessed in real time via the integrated communication interfaces.
   
3. What functions does the data logger offer?
   
   Thanks to its self-sufficient operation even without a network or PC connection, Expert Logger is extremely flexible to use. Its large internal memory of 12 GB enables the storage of up to 360 million measured values, while data transfer to the server or the cloud can be carried out continuously, time-controlled or event-controlled if required. The data logger also has LAN and USB interfaces for seamless integration with PCs or networks. With this device, data can be precisely recorded, independently stored, automatically transmitted and evaluated. The 3D product view gives you a detailed view of the Expert Logger.
   
   
4. Where is the data logger used?
   
   Expert Logger is ideal for a wide range of applications such as data logging, environmental measurement technology, product testing, measured value diagnostics, laboratory data acquisition, experiment and test as well as energy and process data acquisition. It enables autonomous processing of up to 46 analog input channels at sampling rates of up to 1000 kS/s, with each channel being galvanically isolated. The automatic acquisition and pre-processing of measured values takes place at predefined time intervals depending on the requirements of your application.
   
   
5. What are the advantages of the data logger?
   
   Expert Logger enables autonomous measurement data acquisition even where space is limited. With up to 46 analog input channels in the smallest of spaces, it offers flexible recording options for a wide range of sensor signals. The recorded measured variables are automatically pre-processed and saved, while LAN or USB can be used for data transmission. Thanks to integrated interfaces such as PROFIBUS, Modbus and OPC UA, optimum connection to existing infrastructures is guaranteed.
   
   
6. Which sensors can be used with Expert Logger?
   
   The data logger supports a wide range of sensors, including temperature, humidity, pressure, voltage and current sensors. Depending on the application, these sensors can be used flexibly to record and monitor various measured variables. The Expert Logger offers universal analog inputs (mV, mA, thermocouples, RTDs), flexible digital inputs and an SDI12 interface for environmental sensors. Digital outputs and analog outputs are also available for control and regulation tasks.
   
   
7. Which interfaces does Expert Logger support?
   
   Expert Logger offers a wide range of standard and optional hardware interfaces and protocols. This includes OPC UA, PROFIBUS, Modbus, CAN bus, serial interfaces and others that enable optimum connection to the sensor and field level.
   
   
8. The data logger with OPC UA?
   
   The integration of OPC UA into the Expert Logger devices facilitates the acquisition of measured values, monitoring and test stand automation for Industry 4.0 applications. With an integrated OPC UA server and client, the data loggers enable seamless data exchange with other OPC UA-compatible sensors and subsystems. This includes products such as frequency inverters, controllers and regulators that already support OPC UA.
