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.

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.

As manufacturing and industrial operations have become increasingly automated and reliant on electronic systems for safety, the importance of standardized functional safety measures has grown. Protecting system operators and maintaining safe, reliable processes are now top priorities across all industries. Whether you’re protecting workers from injury, preventing environmental spills or avoiding costly equipment damage, ensuring your pressure instruments are Safety Integrity Level (SIL) certified will play a key role in minimizing risk in your critical process applications. For example, when using pressure switches in your application, you will want to consider the SIL rating of your system or device. As a global expert in pressure and temperature instrumentation, we are often asked to explain the benefits of SIL certification. Read this article to learn more about this safety standard, the organization that created it, where SIL-certified instruments are used and the pressure switches we offer that can help prevent worker injury or damage to your equipment.
