Expert Logger is Inobalt‘s new generation of data loggers. It combines the latest communication technology with advanced measurement technology, and is based on FPGA technology to make it especially powerful. It can process up to 46 analog input channels at both low and high rates of sampling. Measurement data can be accurately acquired, independently stored and transmitted to the internet or a PC for evaluation via USB, LAN, WLAN or LTE.


Operation made simple


Sensors are connected via plug-in screw terminals and a chart clearly shows how channels are arranged. Users always have a good overview of the channels despite their high density. Each set of four terminals can be configured as two differential inputs to measure voltage, currents, thermocouples, or to take measurements from a 4-wire RTD.


Configuration - fast and easy


The Expert Logger is simple to configure from a PC. These settings remain stored within the Expert Logger even when disconnected from the power supply. The device settings can also be read out and stored on a PC and analysed offline without the need for a connected Expert Logger. The offline configuration settings are then simply read into the device when connected. The software used for configuration is simple to operate to let users fully focus on their measurement tasks.


Intelligent signal processing


Signal processing using internal software channels significantly simplifies measurement tasks. Flexible calculation channels enable measurement data to undergo further computation and recording. Integrators directly calculate volumes or quantities from time related measurement data such as mass and discharge flow rates. Limit values can monitor measurement data and be used to switch digital outputs or automatically send emails. Complex signal processing is possible using pulse counters, stop-clock functions and operating-hours counter. Averages can be calculated and recorded as time-weighted or moving. The Expert Logger‘s software channels clearly set it apart from other loggers and make it very popular among users.

Expert Logger is available in three versions which differ only in the number of analog and digital inputs they can process. All Expert Logger devices are equipped with internal 4 GB memories that can independently store up to 125 million measurement values with date and time stamps to msec precision. Storage capacity can be extended as required via external USB or LAN storage devices (NAS). An integrated, energy-saving “sleep function“ automatically switches off the device during breaks in measurement acquisition. The Expert Logger operates with standard batteries, rechargeable batteries or solar units.


Precision measurement is ensured through the use of a 24-bit converter. Voltages can also be precision recorded to the μV range. All channels are galvanically isolated to suppress earthing loops and the tried and tested input circuitry protects the device against voltage spikes. Electromechanical components are avoided (relays multiplexer), and the device operates noise and maintenance free. Delphin‘s patented analog inputs guarantee years of reliable measuring work.

 Measurement data analysis included

 

To make it as easy as possible for users to operate the Expert Logger, the powerful ProfiSignal Go software is included free with delivery. ProfiSignal Go enables users to portray measurement data online and offline and to carry out detailed analysis. The software can portray the Expert Logger‘s measurement data in trends. Users can choose between y(t) or y(x) diagrams as well as a range of other analysis diagrams. ProfiSignal Go is especially intuitive to make it highly user friendly.


A range of options


Online / offline analysis and diagnosis of measurement data
A range of trend formats y(t), y(x), digital signal analysis
ASCII / CSV / TDM data exporting
Output or export of trends as EMF files
Analysis using cursor functions
Offline data evaluation is easy and quick to perform. The software also enables fast ASCII exporting of the measurement data for MS Excel™, or conversion into TDM format.
Our customers tell us that it is a pleasure to use ProfiSignal Go.
