Measurement Boxes

The measurement boxes of types MBI16 and MBI32 offer an innovative platform for the acquisition, processing, and display of analog and digital signals. They are modular in design and can be individually tailored to customer requirements.

Housed in a plastic enclosure is the Raspberry Pi with interface or sensor board and optional measurement modules selected according to customer specifications. The signal inputs and outputs are wired on the front and possibly on the back. The Raspberry Pi, as the processing unit, can independently and continuously record measurement values and provides various interfaces for third-party systems.

The modular design allows for customer-specific specifications for each individual measurement box.

The signal inputs are implemented on the front side with 4mm laboratory sockets, allowing laboratory cables to be directly connected. For temperature measurement with thermocouples, common miniature sockets for the corresponding thermocouple are used. Additionally, the measurement boxes offer the possibility to capture up to four pressures via the sensor board.
The measurement boxes can optionally be supplemented with a mobile communication board, allowing measurement data to be transmitted to a cloud system via the mobile network. We also provide cloud services for this purpose. With the Android app, measurement values and results can be displayed online on-site to monitor autonomous operation.

Variants of the Measurement Boxes

The following variants of the measurement boxes are available:

Name

The following connection options are standard:

Front view of an MBI16 with all standard connections

• 2 5-pin sockets for power supply and RS485 interface
• GND: Grounding socket
• 2 yellow laboratory sockets for a short-circuit plug to activate measurement value storage
• Signal LED for operational display and storage in a 1Hz cycle
• 1x USB A (2x USB A for MBI32) on the rear panel
• 1x HDMI socket on the rear panel
• Features of the Measurement Boxes

The base consists of a Raspberry Pi with a specially developed interface or sensor board. This enables the following functions:

Communication via WLAN and LAN

• WLAN access point activatable, allowing data access via Android app
• REST interface for external applications
• Data storage on SD card
• Automated data transfer to USB stick
• Optional live data transmission to the cloud
• Data transmission via Modbus/TCP
• Integration with software such as Trendows
• Configuration via product-specific software ReadRaspi
• Optional communication via the mobile network with additional board or modem stick
• Notification (e.g., via email) for various events
• USB connection, e.g., for the optional use of RS485 or RS232 adapter cables
• 4 differential pressure measurement points with the sensor board
• Internal data logger for autonomous measurement value acquisition
• HDMI connection for external monitor
• Optional version with touch display
• Visualization options in the touch display with symbols and images
• Billing of measurement channels
• Calibration with stored data tables
• Visualization and Operation

With a touchscreen display (MBI32D), measurement values can be clearly displayed on multiple pages. Alternatively, the data can be visualized via an Android app or in a

cloud applicationAreas of ApplicationThe measurement boxes are suitable for, among other things:

Process engineering laboratory and plant measurements

Volume flow measurements of air and gases

• Power measurements on air technology systems
• Emission measurements
• Room climate monitoring
• Fan test stands
• Online monitoring and control in conjunction with the software Trendows
• Networking of Measurement Boxes
• The measurement boxes can be easily networked with each other via the bus connection. The bus connection also includes the power supply, so only one cable is required between the measurement boxes. The connection to the computer is made via an Ethernet connection. Instead of a wired connection, the connection can be made via a WLAN network. Optionally, we can set up the WLAN function of the measurement box as a

"hotspot," allowing multiple measurement boxes to establish a local WLAN network. With Trendows, the entire network of measurement boxes can be monitored and controlled in real-time.

Compatibility with Other Systems
The measurement boxes MBI16 and MBI32 offer comprehensive compatibility with various systems, allowing them to be flexibly integrated into existing infrastructure. Through standardized interfaces such as RS485, RS232, USB, Ethernet, and WLAN, they enable smooth communication with measurement and control systems. Support for the Modbus protocol allows for easy integration into SCADA systems and industrial applications. Additionally, the REST API provides a modern connection to external software solutions, including custom-developed applications. The devices are fully compatible with the software "Trendows" for data evaluation and "ReadRaspi" for configuration and data management. Thanks to these versatile connection options and support for established standards, the measurement boxes are well-suited for integration into heterogeneous system landscapes.
