Delphin - Model Expert -Autonomous Data Logger for Different Measuring Tasks
The FPGA-based Expert Logger device is particularly powerful and enables the processing of up to 46 analog input channels, both at low and high sampling rates. Measured values can be recorded precisely, stored autonomously and transferred automatically via USB or LAN to the Internet or PC for evaluation.
Do you need a highly flexible, compact and universal data logger for your most diverse measuring tasks? Then the Expert Logger is the optimal solution for your application.
With just one device, it is possible to independently process up to 46 analog input channels for your application, both at low and high sampling rates. All channels are galvanically isolated from each other. Your measured values are precisely recorded, monitored, pre-processed and can be stored internally in the device memory. LAN or USB are available for transferring the measured values to a PC or server. Thanks to the integrated interfaces such as PROFIBUS, Modbus and OPC UA, an optimum connection to your existing infrastructure is always possible.
OPC UA is becoming an increasingly established protocol and when used with the Expert Logger devices, measurement acquisition, monitoring and test stand automation applications can be made ready for open data exchange data in accordance with Industry 4.0/Internet of Things.
Both OPC UA servers and clients have been integrated into the Expert Logger devices to enable fast, easy and barrier-free data exchange with sensors and sub-systems also supporting OPC UA.
Many products such as frequency converters, controllers and regulators have already fully integrated OPC UA. The opportunities provided by OPC UA have been identified within the measurement and sensor technology sector with several sensors and actuators now available with OPC UA interfaces.
In addition to OPC UA, Expert Logger devices are also equipped with PROFIBUS, ModBus, CAN-Bus and serial interfaces for sensor and field level connections.

The sensor connection is made by means of plug-in screw terminals. The large connection diagram clearly shows the channel arrangement. Despite the high channel density, the clarity is maintained. Four connection terminals each can be configured as two differential inputs for measuring voltage, current or thermocouples or for measuring a Pt100(0) in four-wire circuit.
Understandable configurationExpert Logger can be configured conveniently from a PC using the configuration programme. The device configuration is retained in the Expert Logger even in a de-energised state. Configurations can be read out and saved on the PC. It is also possible to change the configuration offline without the Expert Logger device being connected. Offline configurations are then simply reloaded into the unit. With Expert Logger, configuration does not become the main task, but users can concentrate fully on the measuring task.
Intelligent signal processingSignal processing by means of internal software channels simplifies the actual measuring task considerably. With the very flexible calculation channels, measured values can be further calculated and stored directly. Integrators calculate volumes or quantities directly from time-related measured values, such as mass or flow rates. Limit values can monitor measured values and be used to switch digital outputs or to automatically send e-mails. Complicated signal processing is also possible by means of impulse counters, time-step functions and operating hour counters. Mean values can be calculated and stored on a time-related or sliding basis. The software channels clearly distinguish Expert Logger from other data loggers and make them very popular with users.
