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.

In many systems, especially those involving high pressure or hazardous conditions, pressure gauge failure can have serious consequences, including operator injury and costly equipment damage. Ashcroft has been a leading innovator in pressure measurement for over a century. We’ve engineered gauges to meet the most demanding safety and performance standards across industries, including oil & gas, chemical processing and power generation. It's our job to make sure customers make the most informed decisions when choosing instruments for their specific processes. For instance, while we know there are plenty of applications where open-front pressure gauges are preferred, solid-front gauges have become a common choice for higher-risk operations. Read this article to learn the differences between solid and open front gauge cases and the benefits they each offer so you can decide which one is right for your application.

When you are installing or inspecting a mechanical pressure gauge, one of the most important things to verify is that the pointer reads zero when there is no applied pressure or vacuum. If it doesn't, the indication could be misleading. That's where pressure gauge features like a zero box and dial pin can help. At Ashcroft, a leading authority in pressure gauges since 1852, we ensure customers have the options they need to maintain accurate measurements and keep their systems running efficiently. Read this article to become well-versed about the difference between a zero box and a dial pin (also known as a stop pin). You will also learn about Ashcroft's TrueZero™ feature and how it takes pressure gauge safety and reliability to the next level. Finally, you can deepen your knowledge further with links to other resources to help you find the right pressure gauge and options designed to address known challenges in your specific application.

In pharmaceutical and biotech facilities—as well as in HVAC systems for cleanrooms, isolation labs, and critical-care environments—maintaining precise and stable differential pressure is essential to prevent cross-contamination, ensure air containment, and meet strict regulatory standards. But monitoring ultra-low pressure differentials can be complex and error-prone with conventional sensors. Ashcroft, a trusted name in pressure instrumentation, addresses this challenge with its GXLdp Differential Indicating Pressure Transducer. Designed specifically for mission-critical, highly pure environments, this pressure sensor ensures reliable, accurate and maintainable performance where it matters most. In this article, you’ll learn what makes the GXLdp stand out with its precision technology, in-place calibration feature, versatile mounting options and the ability to deliver dependable performance right out of the box.

Thermocouples (TC) and Resistance Temperature Detectors (RTD) are widely used for temperature measurement in process industries across the globe. However, in many cases, the sensor is located far from the measuring point. In these instances, cables are needed to transfer the signal. The challenge is to select the correct extension cables to maintain measurement accuracy in long-distance transmissions. Ashcroft temperature solutions are known for their accuracy, reliability and seamless integration into processes. That's why customers often ask us for guidance on how to ensure accurate readings, reduce installation errors and avoid costly downtime due to inaccurate readings. Read this article to learn how thermocouples and RTD extension wires work, why they matter and how to select the correct extension cables for your specific application. You will also learn when transmitters may be a good investment for long-distance signal integrity.
