Flexible data logger for ATEX Zone 0

myDatalogEASY IoT ATEX is a flexible ATEX data logger for outdoor use. It can be used as a gateway in ATEX Zone 2 and detects sensors via radio or 4-20mA up to Zone 0. Two measurement channels are available for the direct connection and supply of sensors (the necessary Zener barriers are integrated in the device). Various supply options are available for operation (mains operation, self-sufficient with PV, rechargeable battery or battery);

The IoT app “myDatalogEASY IoT ATEX” is pre-installed as standard. For the sensor supply, common sensors with associated Zener barriers can be selected from a drop-down list. The sensor supply voltage and the warm-up time are then set to the correct values;

The platform offers additional functions such as device management;

Flexible acquisition and transmission of data in the ATEX area

The myDatalogEASY IoT ATEX is a flexible ATEX data logger and can be used as a gateway in ATEX Zone 2. The device records data from sensors and transmits it to the IoT platform via mobile radio. In addition, two channels are available for direct connection of sensors up to zone 0.

IoT Platform & Studio

The IoT platform is fully integrated and offers countless features in the operation and scaling of your applications. In the integrated development environment Studio you create your application. Libraries and examples are available for this purpose.

myDatalogEASY IoT MPP Tracker mit Solarpaneel

Maximum Power Point Tracker

With the help of the MPP Tracker, the device automatically determines the ideal operating point of the PV module - regardless of the size of the solar panel used. Taking into account the environmental influences (clouds, shading, temperature, ...), the optimum charging power is always achieved.

Loop power supply (4-20 mA Loop Power)

Up to 22V can be fed into the 4-20mA loop for sensor supply of two sensors. The sensor supply is configured via the warm-up time. Individual adaptation to different sensors is possible from one second.

Operation in ATEX Zone 2

The myDatalogEASY IoT ATEX is operated in ATEX Zone 2. Appropriate barriers are integrated in the spacious housing for this purpose. It acquires data from sensors up to ATEX zone 0.

Operation with PV panel in ATEX zone
myDatalogEASY IoT can be operated autonomously in zone 2. The system can measure a 4-20mA sensor every minute on two channels. For the supply of the sensors, a time can be stored with which the sensor is supplied with power before the measurement in order to obtain a stable measurement signal.
Flexible selection of Zener barriers for use in Zone 0
The two 4-20mA inputs can be individually fitted with the required barriers. A list of ATEX parameters is available for selection. This covers all 2-wire mA sensors available on the market. This means that the sensors can be used in zone 0.

Overview graphic - myDatalogEASY IoT ATEX is placed in zone 2. Sensors can be attached wired or via Bluetooth up to zone 0.

Autonomous operation in the ATEX zone

Operate application in ATEX zone without existing infrastructure.

The 30W solar panel is supplied with a pole mounting bracket for poles from 60 to 300mm. The panel provides the power for autonomous operation of two 4-20 mA / 15V probes, which operate with a measurement interval of 1 minute and require 20 seconds warm-up time.

With the outdoor mounting box (340x200x150mm), the myDatalogEASY IoT ATEX is mounted on the masts. A vandal-proof multi-band antenna is already integrated in the box. The outdoor mounting box is also UV-resistant.

Sensors in the ATEX Zone

For flow and level measurements, up to two radar sensors can be operated with the myDatalogEASY IoT ATEX.

The sensors are adapted for use in the ATEX zone. Power is supplied via the data logger. The required barriers are permanently installed in the appliance.

If your sensor is not on the list, please email us at support@microtronics.com. We will then establish whether it can be used with the myDatalogEASY IoT ATEX, determine the necessary zener barrier and recommend configuration settings and expected runtime.

Product configurator

You can use the runtime calculator to estimate both the autonomous runtime of the application and the associated costs. Actual costs and energy consumption depend on measurement conditions such as reception quality and ambient temperature. You can find detailed information on the tariffs here.
