Whether you're monitoring hydrogen pressure, operating in high-vibration compressor systems, or designing for hygienic environments for sanitary food and beverage processing, reliable pressure measurement is essential to safety and process integrity. However, finding a pressure gauge that offers both durability and easy field serviceability can be difficult, especially in corrosive environments where access for instrument recalibration is critical. Ashcroft, a leading authority in pressure and temperature instrumentation, offers a solution designed to perform in challenging conditions and make field maintenance and OEM installations less challenging. Read this product review to learn about the Ashcroft® 8009S Pressure Gauge, an economical, all stainless-steel solution engineered to perform in challenging conditions. By the end of the article, you will know if this instrument is the right one for your needs.

Ensuring accurate and reliable temperature readings in harsh industrial applications is vital. The challenge is protecting your temperature sensor from the damaging effects of corrosive media, high pressure and velocity in industrial applications. That's where thermowells can help. However, with so many types of thermowells and styles of thermowell shanks, it may not be immediately clear how to select the correct one for your application. As a leading manufacturer of temperature instruments, Ashcroft offers multiple styles of thermowells, including threaded, flanged, socket-weld, weld-in and sanitary. Each style can be manufactured with one of three shank types: straight, tapered or stepped. Depending on the shank, there are implications for strength, sensor response time and vibration resistance. The type you choose will ultimately depend on the demands of the application. Read this article to learn the differences between thermowell shank types, their main benefits and applications, and to understand how factors like wake frequency calculations can help you make the most informed and efficient decisions.

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.

These systems operate at extremely low temperatures, typically below -150 °F, and introduce a unique set of pressure measurement challenges. Instruments exposed to these conditions must withstand intense thermal stress, potential material brittleness and design limitations due to space constraints. At Ashcroft, we understand the implications of these conditions and know how to take precautions to prepare for potential pressure gauge failure. Our pressure measurement expertise relating to industrial systems, including cryogenic applications, helps ensure reliable performance, process safety and long-term instrument protection. Read this article to learn more about cryogenics, how to measure pressure in these applications, and how to protect your instruments from the effects of very low temperatures.

When selecting a mechanical pressure or temperature gauge, many engineers and technicians focus on the gauge’s range, accuracy or material compatibility. But did you know the pointer type can be just as critical? The wrong pointer can result in poor visibility, missed pressure events, or other system issues. With so many options to choose from, it can be difficult to know which pointer type is the best fit for your application. As a trusted authority in pressure and temperature instrumentation, Ashcroft has helped customers across industries, from energy and water treatment to OEM and chemical/petrochemical applications, identify the right pressure monitoring solutions for over a century. In this article, part of our “Understanding the Basics” series, we’ll walk you through several common pointer types, show you how they work, what they’re best used for and the pros and cons of each. Read on to help you decide which pointer is the best for your needs.
