When measuring pressure in challenging environments involving extreme temperatures, your instrument must perform accurately and reliably. Temperature exposure can come from many sources, including the process media and the ambient temperature surrounding the sensor. Each affects the transducer differently, but media temperature has the most direct impact because it acts on the sensing diaphragm and internal components. As media temperature rises or falls, it can distort readings, shorten sensor life or even damage components. With more than 175 years of pressure and temperature measurement expertise, Ashcroft is recognized as an industry authority in helping customers maintain reliable measurement in even the harshest environments. In this article, you’ll learn how process media temperature can impact pressure transducer performance, what causes output changes and how to minimize errors through proper design and installation. Understanding this information will help ensure you protect your instruments from performance drift or premature failure.

Because these systems operate continuously and consume significant energy, even small inefficiencies can drive up operating costs. At Ashcroft, a leading producer of pressure instruments for multiple industries, including HVAC, we provide insights and recommendations to engineers and facility managers like you to help improve system performance and reliability. For instance, we know that instrument accuracy is one of the most important factors in maintaining HVAC efficiency. Pressure sensing instruments, like transducers, monitor the system’s conditions and help automation controls that adjust fan speeds, pump flows and valve positions. Inaccurate sensor measurements can cause systems to overwork, leading to wasted energy and unnecessary expense. Read this article to: Examine how HVAC systems function and the factors that can influence measurement reliability. Learn how pressure sensors optimize HVAC system performance Understand why accuracy is so important Compare the different methods used to determine accuracy By understanding these elements, you’ll be better equipped to evaluate pressure sensors that support both building performance and cost savings.

Pressure sensors are a critical part of any hydraulic, HVAC or industrial process system. When specified correctly, these instruments can ensure safe operation, accurate performance and long equipment life. The wrong pressure sensor, however, can lead to inaccurate readings, process inefficiencies, equipment damage, or operator safety risks. While sensing technology will ultimately dictate what sensor is best for your application, the following factors also need to be considered. By understanding them, you can avoid common pitfalls and protect your system’s integrity. At Ashcroft, we’ve helped engineers and OEMs navigate these challenges for decades. Read this article to learn: The five essential factors to consider when selecting a pressure sensor Why media compatibility, hydraulic shock and reference type matter How accuracy definitions differ and what to look for The role of interchangeability in long-term system reliability You will also see links to additional resources that can help deepen your knowledge about pressure sensors even more.

This article was originally published on September 19, 2022, and updated on August 13, 2025. 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.

Maintaining accurate and stable pressure measurements is a constant challenge in demanding applications, particularly as pressure sensors age or are exposed to extreme conditions such as vibration, temperature fluctuations or pressure cycling. This can lead to loss of stability, causing your sensor to drift outside of its specified range. When this happens, you have an important decision to make: recalibrate or replace your instrument. As a trusted leader in pressure measurement technologies, Ashcroft brings over 170 years of engineering expertise to support process applications across multiple industries. Read this article to learn more about zero and span adjustability, why it’s important to long-term sensor performance, the benefits and limitations of using adjustable pressure transducers and ow to determine when recalibration is needed. Read on to discover how pressure transducers with zero and span adjustability can improve your system’s reliability and help you avoid costly interruptions. You will also see links to additional articles and resources to help deepen your knowledge about this topic even further.
