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.

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.

This article was originally published on May 10, 2021, and updated on April 2, 2025. The industrial and OEM markets offer a wide variety of pressure transducers, each with its own price range. The challenge is finding the best instrument for your specific application at a cost that aligns with your budget. Having spent over 20 years in the pressure sensor/transducer industry in roles related to product management and sales, I've gained firsthand knowledge of the numerous factors that affect pricing. In this article, you will gain insight into these cost drivers so you can make a more informed decision about your transducer purchase. Please note, we are purposely excluding automotive/appliance and process transducers/transmitters from this discussion, as their market and cost structures are unique. Also, for clarity, the term “pressure transducer” refers to the complete assembly of the pressure sensor and output board, which some industries might also call a pressure sensor or transmitter. In this article, "pressure sensor" will indicate the sensing element or technology itself, which is part of the full pressure transducer product.

Accurate low-pressure monitoring is crucial for safety in air flow measurement, leak detection systems cleanrooms, isolation rooms and other critical applications in healthcare, semiconductor manufacturing and more. However, measuring very low pressures in small volumes with accuracy and repeatability requires a specialized sensor. It is the sensor’s design, manufacturing process and installation method that will determine whether or not it can deliver the long-term stability, accuracy and resolution necessary to provide meaningful measurements. That's where microelectromechanical systems (MEMS) can help. Ashcroft, a recognized leader in pressure and temperature instrumentation, and its parent company Nagano Keiki Co. LTD have a proven track record of manufacturing excellence in low-pressure pressure sensors with MEMS technology. Read this article to learn more about MEMS, how it works in low-pressure applications and the pressure sensors available to keep low-pressure environments working with precision and reliability.
