The Microtronics myDatalogEx is an ATEX data logger for the mobile data acquisition of industrial sensors.

The myDatalogEx is a portable device for the acquisition and transmission of 3rd party sensors. The industrial sensors are recorded via the analogue standard interface 4-20mA. A switchable sensor supply is provided by the myDatalogEx.

A smartphone app is provided for simple and convenient initial operation at the measuring point. The myDatalogEx communicates via BLE (Bluetooth Low Energy) with the app. The data is transferred to the central web platform via 3G.

The device is suitable for use in:

  • Sewage systems
  • Industrial plants
  • Municipal water and wastewater systems
