myDatalog

Robust data logger for measuring and transmitting sensor data in ATEX zone

The myDatalog is a robust, chemical-resistant data logger for measuring and transmitting sensor data in the harsh environment. The IoT device can be connected with up to 4 Bluetooth BLE sensors. Optionally a 4-20mA input with switchable and adjustable sensor supply (from 0.1 seconds; 0..22V) is available.

Applications:

  • Stormwater overflow basin
  • Combined sewer
  • Indirect Discharge Controller
  • Level measurement
  • Flow measurement for billing

Pressure and radar sensors for level measurement are available for the myDatalog. The compatibility of further sensors will be checked on request.

Runtime of up to 8 years with ultra low power technology

The runtime of the myDatalog is convincing in the BLE variant with a runtime of up to 8 years (at 10sec. measurement interval and daily mobile radio transmission of the data). If a sensor is supplied via the mA input, a runtime of up to two and a half years is achieved (at 5min. measuring interval, 1sec. warm-up and 24h transmission interval).

myDatalog und myDatasens werden in der ATEX Zone 1 eingesetzt

ATEX Zone 1

The myDatalog is certified for use in the hazardous environment. The data is transmitted via mobile radio or Bluetooth directly from ATEX Zone 1 ( II 2G Ex ib IIB T3 Gb) to the integrated online platform.

Multiple sensors with one device

With the myDatalog, the data from several sensors are captured and transmitted. It is possible to combine one mA sensor with up to four BLE sensors.

Supply, record and transmit 4-20mA sensors in ATEX zone

The mA input on the myDatalog can be used to supply 4-20 mA sensors directly in ATEX Zone 1 ( II 2G Ex ib IIB T3 Gb). The device feeds up to 22V into the 4-20mA loop. For the myDatalogEx, sensors have already been tested with regard to their compatibility and a corresponding proof of intrinsic safety has been provided.

  • Hydrolevel® sensor of the SPK series
  • Radar level sensor Micropilot FMR20
  • Radar sensor Vegapuls C21
  • Hydrostatic level transmitter Waterpilot FMX21

Other sensors are available on request.

BLE pressure and radar sensor

With the Bluetooth Smart (BLE) interface, up to four BLE sensors are detected in the ATEX zone and the measured values are transmitted to the platform. Configuration is also performed via the platform.

  • Pressure sensor myDatalogGauge
    It is possible to create base point tables for special container geometries with trigger and alarm functionalities.
    For parameterization (offset and trim) at the measuring point, the GaugeBuster app for Android and iOS is available free of charge.
  • BLE radar sensor
    With the BLE radar sensor, you’ll never miss an event in the channel again. The sensor is mounted wirelessly in the duct. The enormously low energy consumption leads to a runtime of up to 10 years. The mounting bracket and bubble level directly on the BLE radar sensor facilitate installation and bring maximum measurement precision.

Product configurator

With the help of the runtime calculator, you can estimate the autonomous runtime of the application as well as the costs incurred. The actual costs and energy consumption depend on the measurement conditions, such as the reception quality and ambient temperature. Detailed information on the tariffs can be found here.
