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.

This article was originally published on March 13, 2019, and updated on July 16, 2025. In many process industries, sudden pressure surges from water hammer, valve closures or equipment malfunctions can cause overpressure events that damage pressure gauges and lead to equipment failure and costly downtime. To reduce this risk, many systems rely on external pressure limiting valves (PLVs), which increase installation complexity and create potential leak paths. Ashcroft offers a smarter solution: pressure gauges with built-in overpressure protection. With over 170 years of innovation behind us, Ashcroft understands the harsh realities of industrial applications and we engineer products that perform in the most extreme conditions. Read this article to learn about two pressure gauges that are designed with XRA Overpressure Protection to handle pressure surges internally, eliminating the need for external components and improving system reliability.

Temperature measurement in an ammonia compressor in industrial refrigeration is crucial to ensure system efficiency, operational safety and early detection of problems. Because ammonia can be hazardous to your health, reactive, corrosive, flammable, and in some cases explosive, selecting and installing your temperature measurement equipment demands strict adherence to established standards and best practices. At Ashcroft, we’ve built our reputation on delivering accurate and reliable pressure and temperature instrumentation for mission-critical environments. Read this article to learn how temperature is monitored in a refrigeration system's compressor, and what to look for when selecting the best temperature measurement instruments to monitor ammonia systems safely and effectively. You will also see links to additional resources about temperature sensors for your reference.
