Continuous Data Acquisition at Decentralised Measuring Points
Delphin Technology Loggito series is a new compact and flexible measurement system for the data acquisition Industry IoT. It enables inexpensive connectivity of decentralized measuring points for both low-channel data logging and complex acquisition systems.
Measurement data can now be acquired decentrally, on-site, or centrally and viewed from anywhere using any type of user device. Loggito is highly adaptable to decentralized data acquisition and monitoring of dispersed measurement points:
- For the inexpensive establishment of a decentralized measurement network
- For low-channel measurement tasks in laboratories
- For process analysis with flexible numbers of channels
- Uses universal sensor inputs for a range of different sensor types
- Options for scalability and extensibility
Delphin Technology Loggito Live Measurement Data on any User Device
In combination with ProfiSignal Web software, measurement data can be viewed live anywhere on a desktop, notebook, tablet, or smartphone. Vital data can also be summarised in a graphical dashboard view.
Loggito extension module
Loggito can be connected via LAN, USB, or WLAN. The Loggito Logger is equipped with an internal data storage capability to enable internal processing and the computation of measurement channels. The extension module Loggito USB is scalable to the required number of channels, e.g. in control cabinet applications, for flexible and highly cost-effective measurement solutions via direct PC connections.

Delphin Technology Loggito Models
The Loggito series is comprised of the Loggito Logger (master) and the USB extension module. The Loggito brings flexibility to measurement and control technology and provides data access from the mobile devices of users.
Loggito Logger
The Loggito Logger is equipped with an internal data storage capability to enable internal processing and the computation of measurement channels. When combined with the USB extension module, the Loggito Logger acts as a coordinator for establishing decentralized measurement networks via USB.
USB Extension Module
The Loggito USB module fulfills two functions:
- USB modules enable the required number of channels to be provided, e.g. in control cabinet applications. Power is provided directly via the USB without the need for an internal power supply unit. The USB module does not require an internal storage capability because data logging is undertaken by a main Loggito Logger.
- The USB module can also be connected directly to a computer. This gives you a highly inexpensive and flexible measurement system, e.g. for measurement stations in a laboratory.
Delphin Technology Loggito Software
The Loggito Logger is equipped with integrated software channels for online analysis, monitoring and automation functions. By using the ProfiSignal Web software, a multitude of web functions can be realised. The ProfiSignal software provides users with a powerful PC-based tool for measurement technology.
Software Channels in the Loggito Logger
- Online processing during acquisition using internal software channels
- Calculation and statistical channels compute, monitor, count, and integrate measurement data
- Limit detector to monitor limit and limit values
- Status detector to evaluate status information and to issue alerts in the event of an mA-signal failure
- A trigger automatically performs setpoint curves with reset, stop/start triggers
- Timer channels provide, for example, time-delayed starts for experiment procedures
ProfiSignal Web: Live Measurement Data on any User Device
- Mobile access to live measurement data from any user device
- Live data, historical data, and process parameters in an individually adjustable dashboard
- Data storage capacity with cloud functions within the Loggito Logger (measurement technology for edge cloud computing)
ProfiSignal: PC-based Measurement Technology
- Online and off-line analysis and visualization of measurement data
- Creation of automated testing procedures
