Selecting the Right Indicator for Test and Measurement Applications

Precision is non-negotiable in the realm of test and measurement. Accurate force measurement is essential for validating aerospace components’ safety, ensuring medical device consistency, and optimizing manufacturing processes.

Sensor indicators are a critical link between load cells, torque transducers, multi-axis sensors, and actionable data. By converting minute electrical signals into clear, interpretable readouts, indicators empower product designers, testing professionals, and engineers to make informed decisions, drive innovation, and ensure product reliability.

The Indispensable Role of Indicators in Critical Applications

Indicators are instrumentation devices that are not merely data displays but integral to the integrity of force measurement systems. They are used in all types of industry testing projects and programs. Here is a quick review of how they contribute to success in various test and measurement applications:

Aerospace Test and Measurement

Applications for aerospace wing stress analysis, landing gear impact tests, and engine thrust measurement require high-accuracy indicators with fast sampling rates, such as the 9870 High-Speed High-Performance TEDS Ready Indicator. These indicators capture dynamic forces during critical tests, ensuring structural integrity. TEDS compatibility streamlines calibration, which is crucial for upholding stringent quality standards.  Find additional aerospace solutions here.

Top 10 Criteria for Selecting the Right Indicator

Choosing the optimal indicator is crucial for achieving accurate and reliable results. The following are recommendations for reviewing indicators for your particular use case.

#1 Sensor Compatibility: Ensure the indicator supports the sensor’s output signal (mV/V, voltage, current). Verify compatibility with TEDS for simplified calibration.

#2 Accuracy and Resolution: Select an indicator with sufficient accuracy and resolution for your specific application. Consider the indicator’s linearity, hysteresis, and temperature stability.

#4 Sampling Rate: Choose a high sampling rate indicator for dynamic measurements to capture rapid force changes. The 9330 and 9870 are good examples of high sample rate indicators.

#5 Connectivity and Output Options: Determine the required output options, including analog, digital, and wireless features. Confirm compatibility with your data acquisition system.

#6 Form Factor and Portability:  Choose a form factor that suits your testing environment. Do you prefer or need a handheld, panel-mount, or rack-mounted indicator? What type of enclosure is best suited for your application? Are cables a consideration? Consider portability requirements for field testing.

#7 Environmental Considerations: When necessary, review indicators with an enclosure that can withstand the operating environment. This includes extreme temperatures, humidity exposure, or areas subject to noise and vibration.

#8 Software and Data Logging: Evaluate the indicator’s software capabilities for data logging, analysis, and visualization. Consider if the unit has built-in logging or PC-based software.

#9 Calibration and Maintenance: Understand the indicator’s calibration procedures and maintenance requirements. Utilizing TEDS greatly simplifies calibration.

#10 Feature and Function: Different indicators are better suited to capacities, configurations, connectivity, data management, and variability. Invest in carefully reviewing the features and functionality when pairing with your sensors. Considering system-level calibration when choosing an indicator is essential to guarantee they are perfectly aligned and performing as a unit.
