Low-pressure transducers are essential in applications like HVAC systems, cleanrooms, critical environments, and pharmaceutical operations. These systems often require the pressure sensor to be mounted away from the source, sometimes by several feet or more. What many don’t realize is that the pressure sensor tubing length can influence system behavior in subtle but important ways. While accuracy may remain intact, signal response times can vary depending on how the system is configured. Ashcroft has been supporting critical low-pressure systems for decades, helping engineers and facility managers design pressure measurement setups that remain responsive and stable, even when tubing runs are long. Read this article to learn how pressure tubing works, what impact tubing length has on your system and pressure instruments, and how to enhance your system design for performance and reliability.
