Sensing Technology

digiBOX Industrial can be freely configured with (2-4) inputs for both strain gauge based and piezoelectric sensors. HBK provides a range of sensors for both sensing technologies that measure:

  • Strain
  • Force
  • Load
  • Torque
  • Pressure

The sensor inputs are synchronized sample synchronous, enabling challenging industrial measurements with a 40 kS/s sample rate and 24-bit AD conversion for both input technologies.     

Signal Processing

digiBOX Industrial features integrated statistical functions developed for industrial measurement applications:

  • 4x Min, Max, and peak-to-peak tracking
  • 4x capture values
  • 8x limit switches
  • Sum channel (coming soon)

These values are calculated every 25 µs. This enables the execution of complex and demanding process control applications leveraging the digiBOX as decentralized process controller.

Additionally, the digiBOX features an intuitive webserver which is used to configure and parametrize the device. This allows for an efficient system setup and servicing of the digiBOX. 

IT/OT Interoperability

digiBOX Industrial offers parallel IT/OT interoperability ensuring seamless integration with a machine's PLC system while simultaneously making measurement data, calculated results and device parametrisation accessible to IT-level applications without compromising the ongoing PLC process.

This provides the IT-Level with critical process data from force measurement processes, enabling new possibilities such

  • historical data storage and tracking
  • complex monitoring
  • data acquisition (miniDAQ) and analysis
  • building machine learning models
  • digital twin applications
  • Remote access and cloud integration

These capabilities are easily implemented using the integrated openDAQ™ protocol, which allows for streaming 40 kS/s sensor data and seamless integration into programming environments based on Python, C# and C++.

Strain Gauge Technology and Applications

Strain gauge-based sensors provide highly accurate, drift-free measurements for both static and dynamic applications. Their measurement principle allows for tensile and compression measurements, making them the optimal choice for process control and monitoring applications, and reference standards.

digiBOX, when combined with strain-gauge sensors is ideally suited for force measurements such as

  • force joining processes
  • press applications (load monitoring, sheet metal forging, tablet/powder pressing)
  • assembly processes
  • industrial process control applications (process monitoring, end-of-line testing, handling systems)
  • monitoring applications (tooling, processes)

All mentioned processes can be realized with using force, torque, pressure or strain sensors depending on the specific application.

Piezoelectric Technology and Applications

Piezoelectric sensors offer a wide measurement range, making the suitable for applications with high preloads (high overload capacity). Their compact size makes them ideal for installations where space is limited.  While they excel in dynamic measurements, they are also effective for quasi-static applications.

digiBOX when combined with piezoelectric sensors is ideally suited for

  • force joining processes
  • punching and clinching tools
  • spot welding and resistance welding
  • Measuring low forces under high preloads
  • assembly and testing
  • process and quality control applications

HBK offers piezoelectric force, torque, pressure and strain sensors. In combination with a new low-latency software reset function integrated into the digiBOX signal-path, dynamic processes with short cycle times can be efficiently achieved.  

Piezoelectric and Strain-Gauge Technology Combined

The K-DBX-4M variant features sensor inputs for two strain-gauge and two piezoelectric sensors. This allows customers to combine these measurement technologies, leveraging the sample synchronous data acquisition for both sensor technologies. This unique combination of sensor setups enables more cost-effective solutions and highly precise teach-in procedures.

The digiBOX K-DBX-4M variant allows for a sample synchronous calibration procedure of strain-gauge and piezoelectric sensors, ensuring the most accurate calibration results. This is realized with an automated calibration assistant (coming soon) 

IT-Level connectivity allows for new solutions

  • It is possible to integrate the digiBOX into cloud services and realize remote access for monitoring and parametrization tasks
  • The vertical integration into productivity software is also possible and allows for analysis of product quality and enables process traceability
  • Leveraging the 40kS/s data streaming with the openDAQ protocol can be used for DAQ analysis tasks in parallel to the running process
  • Connecting the digiBOX to edge devices can be used to train machine learning algorithms for process optimization and digital twin solutions
