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.

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.

In any process where accurate temperature monitoring is critical, from power generation and HVAC systems to food processing and pharmaceutical manufacturing, Resistance Temperature Detectors (RTDs) are one of the most trusted sensor technologies. Selecting the right RTD element is essential for achieving high performance, long-term stability and compliance with industry standards. Ashcroft, a global leader in temperature and pressure instrumentation, has decades of experience helping customers specify, install and calibrate RTDs in demanding environments. Read this article to learn about RTD sensing elements, how they work and how to select the right element based on industry requirements, construction, accuracy, wiring and environmental factors.
