Data loggers for strain gauges

Data loggers for static strain measurements – Precise recording of long-term loads

For applications where the exact measurement of static or slowly changing strain is essential, specialized data loggers are indispensable. These systems are typically used in combination with strain gauges and are designed for precise recording over extended periods. The loggers are engineered to maintain high measurement accuracy and stability even when detecting minimal signal changes.

Features and technical characteristics

• High measurement resolution and stability
  Specifically designed for small signal changes to enable low-drift measurements over long periods.
• Compatibility with strain gauge bridges
  Supports quarter-, half- and full-bridge configurations – ideal for standard strain gauges.
• Multi-channel versions
  For simultaneous recording of multiple measurement points, for example on large steel structures or test benches.
• Extended storage capacity
  Suitable for long-term measurements involving large volumes of data.
• Energy-efficient design
  Long battery life for use at measurement locations that are difficult to access.
• Temperature compensation
  For precise measurement results even under changing environmental conditions.

How do you choose the right static strain measurement system?

Selecting a suitable static strain measurement system depends strongly on the specific measurement task, the sensors used and the requirements for accuracy and long-term stability.

• Number of measurement channels
  Depending on the application, several measurement points may need to be recorded simultaneously. A high channel count is often required, particularly for structural or load analyses.
• Supported strain gauge types and bridge configurations
  The data logger should be compatible with the strain gauges used and support different bridge configurations such as quarter-, half- or full-bridge.
• Measurement accuracy and resolution
  High resolution and low measurement deviation are essential for recording very small strains.
• Long-term stability and drift behavior
  For static measurements over extended periods, stable and low-drift data acquisition is particularly important.
• Sampling rate and measurement speed
  Static applications usually do not require extremely high sampling rates, but they do require stable and continuous data acquisition.
• Temperature compensation
  Temperature changes can affect measurement results. Systems with integrated temperature compensation can significantly improve measurement accuracy.
• Data storage and software
  Powerful software for visualization, analysis and documentation of measurement data greatly simplifies evaluation.
• Mobility and operating environment
  Depending on the application, portable measurement systems or stationary solutions may be required. Environmental conditions such as temperature, humidity and vibration should also be considered.
• Expandability and system integration
  Modular systems make it easy to add additional channels or sensors at a later stage.
