Frequently Asked Questions

A: Tubing characterization is a crucial process that our team employs to meticulously analyze the dynamic response of a pressure tap, tubing, and transducer assembly to arbitrary pneumatic inputs. To facilitate this process, we utilize our proprietary Pulsar handheld device, enabling users to capture the dynamics of their tubing system in-situ. Subsequently, our specialized software assists users in calculating the necessary parameters for signal reconstruction. These parameters are then applied to correct and reconstruct pressure signals acquired during tests, ensuring that the data reflects the actual aerodynamic conditions with minimal distortion or attenuation caused by the system's inherent characteristics.

A: While keeping the tubing system short can minimize the delay and attenuation effects commonly associated with longer tubing, it doesn't eliminate the need for signal reconstruction, especially in high-precision aerodynamic measurements. Short tubes still introduce some level of distortion due to pneumatic resonance or other factors that could affect the fidelity of pressure signals. For instance, consider a scenario where the tubing length is relatively short (0.6 m / 24 in), yet resonance becomes the dominant effect in the tubing system's response. This resonance can lead to a 0.1 psi overshoot in peak pressure measurements, which, when translating dynamic pressure via a probe, could result in a significant 35 m/s error in velocity readings.

A: The necessity to repeat the characterization process largely depends on the stability of the tubing system's geometry. If the geometry remains consistent, there's no need for frequent re-characterization; the parameters derived from the initial process will continue to be applicable for subsequent measurements. This durability of parameters underscores the efficiency of our characterization process, allowing for extended use without the need for regular recalibration. However, should there be any alterations in the tubing system—be it from environmental impacts, physical modifications, or damage—it's crucial to undertake a new characterization. Changes in the system can affect its dynamic response, making previous parameters potentially inaccurate for capturing the true aerodynamic conditions. We advocate for a new characterization in such instances to ensure the parameters accurately reflect the current in-situ geometry, maintaining the precision and reliability of your measurements.

A: Absolutely! We understand that some of our clients may have unique or one-off requirements that do not necessitate the purchase of our hardware. For these situations, we offer a service where we can conduct the tubing system characterization for you. Once the characterization is complete, we provide customized software solutions tailored to your needs. These solutions can be delivered as Windows Dynamic Link Library (DLL), LabVIEW VI, or MATLAB MEX functions, enabling you to seamlessly integrate the reconstruction capabilities into your existing setup. This service ensures that you can benefit from our advanced signal reconstruction technology, even without our hardware.

A: Our system comes with a LabVIEW VI Package, designed to streamline the integration process by offering a comprehensive palette of queries and commands tailored for use with our Chronos system. This package facilitates easy and efficient setup, allowing users to quickly implement a wide range of functions and commands essential for their data acquisition routines. Installation is straightforward, accomplished through the VI Package Manager, ensuring that users can seamlessly incorporate the package into their LabVIEW environment and start utilizing its features without delay.

A: Yes, we can certainly perform characterization on air data or multi-hole probes, tailored to the specific requirements of each probe's geometry. Whether it involves the entire probe tip or individual ports, our team has the expertise to accurately assess and characterize the dynamic response of these complex systems. Following the characterization, we offer to package the results into functions compatible with the software environment you prefer, be it Windows DLL, LabVIEW VI, MATLAB MEX, or another platform.

A: The Chronos System provides a significant advantage by streamlining the setup process and reducing costs associated with aerodynamic testing. By negating the need for surface-mounted pressure transducers, it not only simplifies the test preparation but also minimizes potential disruptions to the test surface, all while maintaining the high accuracy levels required for precise measurements. This efficiency in setup and cost savings, combined with the system's reliability and accuracy, makes the Chronos System an invaluable tool for aerodynamic testing across a variety of applications.

A: The integration of the Chronos System with your existing hardware and software setups is made straightforward through our Presa API. This API provides a robust and flexible interface that facilitates seamless communication between the Chronos System and a wide range of testing environments and platforms. Whether you're using specialized aerodynamic testing software, general-purpose data acquisition tools, or custom-built systems, the Presa API ensures that the Chronos System can be easily incorporated into your testing infrastructure using TCP queries. This compatibility extends the capabilities of your current setup with minimal adjustments required, enabling you to leverage the advanced unsteady pressure measurement features of the Chronos System.  

A: Absolutely, the Chronos System is designed to accommodate a wide range of aerodynamic testing needs, including both steady and unsteady pressure measurements. Leveraging Direct Temperature Compensation (DTC) pressure scanners, our system is capable of capturing high-fidelity, instantaneous pressure data, making it ideal for dynamic testing scenarios. For applications requiring steady-state pressure data, users have the flexibility to calculate average values over a specified time period directly from the raw data. Alternatively, for steady measurements, you can choose not to apply the signal reconstruction process, utilizing the system's capability to directly measure static pressures without the need for complex processing.

A: The ability to reconstruct pressure measurements across the frequency spectrum is influenced by the specific geometry of the tubing system and the prevailing noise levels. Generally, for a tubing system with a length of 1 meter (40 in) and an internal diameter of approximately 1mm (0.04 in), we can achieve reconstruction of signals up to 800 Hz.

A: Yes, we specialize in supporting field applications across various industries, including automotive and wind energy, where tubing-based pressure measurement systems are pivotal for aerodynamic testing. Tubing provides excellent isolation for pressure transducers, protecting them from potential damage, but introduces uncertainties in the dynamic measurements. Our services include comprehensive characterization of tubing systems and the development of tailored data acquisition systems for challenging and space-constrained field applications.
