Delphin Technology Loggito

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 Functions (Measurement Hardware Component)

  • Cloud functioning through the installation of ProfiSignal Web software (measurement technology for edge cloud computing)
  • Mobile access to live measurement data from any user device
  • Dashboard displaying current process parameters live data, and historical data

Modbus and OPC UA

  • Modbus interface (optional)

Versatile Sensor Input Modules

  • High-precision, universal sensor inputs
  • Universal analog inputs (mV, mA, thermocouple, RTDs)
  • Modules channel variants: I/O modules with a range of different channel numbers, universal analog inputs and digital inputs and outputs

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.
