Autonomous data logger for different measuring tasks

The FPGA-based Expert Logger device is particularly powerful and enables the processing of up to 46 analogue input channels, both at low and high sampling rates. Measured values can be precisely recorded, autonomously stored and automatically transferred to the internet or PC via USB, LAN or WLAN and evaluated.

The multi-channel data logger for complex data acquisition

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 unit, the autonomous processing of up to 46 analogue input channels, both at low and high sampling rates, is possible for your application. 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, USB or WLAN are available for transmitting the measured values to a PC or server. With the help of integrated interfaces such as PROFIBUS, Modbus and OPC UA, an optimal connection to your existing infrastructure is always possible.

With an OPC UA interface

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.

Operation made easy

Detachable screw terminals

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 configuration

Expert 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 processing

Signal 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.

Expert Logger – Type 100, Type 200, Type 300, Type 400

Expert Logger is available in four versions which differ only in the number of analog and digital inputs they can process. All Expert Logger devices are equipped with internal 12 GB memories that can independently store up to 360 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.

Software channels as extended functions

Realise and execute monitoring and automation tasks easily 

The Delphin measuring and testing devices have extended functions that are summarised under the term software channels. The online measurement data is calculated with the software channels and then used for visualisation, storage or control.  

In this way, entire programme sequences can be configured very simply and intuitively with the regulation and control function. These then run autonomously without PC support. This is how you use your data logger effectively, also as a monitoring device or PLC replacement. 

The software channels enable functions such as limit value monitoring, integration or online calculation and are configured very easily. This means that even users who are not experts in programming can easily implement their own monitoring tasks or balancing independently in the unit.
