Freezing temperatures can damage sensitive electronic pressure-measuring instrumentation, such as a pressure transducer/transmitter. Regardless of whether an operator tries their best to remove all the water from their system to prevent freezing, it is still possible that a small diaphragm cavity or pressure passage within the transducer's sensor will retain water. When this water freezes, it can cause excessive pressure on the sensor diaphragm element, exceeding its normal range of motion, and resulting in permanent distortion. Even when the ice melts with warmer temperatures, the transducer will no longer be able to return to its original zero position, making it unusable and necessitating replacement. Ashcroft, a leading manufacturer of pressure and temperature instruments since 1852, has explored this challenge extensively and offers a solution to help you prevent this from happening in your water-based applications. In this article, we will discuss what exactly happens to pressure-sensing instruments when they are exposed to freezing temperatures, the common applications where this occurs and a cost-saving solution for protecting your instruments and keeping your operation running effectively.

If you work in semiconductor manufacturing, you understand that the process requires highly specialized equipment and instruments that can handle harsh applications involving corrosive gases and chemicals. Transducers, for example, are critical for measuring pressure throughout the production process to control the flow and distribution of ultra-high purity (UHP) gases safely and effectively. However, not all transducers can handle such challenging conditions. That’s why selecting the right one for your operation is a critical step in ensuring the successful creation of your product. Ashcroft and our parent company Nagano Keiki Co. LTD, have a long and proven track record of supplying pressure and temperature instrumentation to semiconductor manufacturing customers worldwide. This article will share our insights into semiconductor UHP gas processes and the unique challenges for pressure measurement instrumentation used in semiconductor applications. It will also review the best types of pressure transducers that are designed for these complex processes.

What do race cars, off-highway vehicles (OHV) and any other high-performance machine or system have in common? They are only as good as the instruments you find under the hood. In fact, something as small as the pressure sensing device can have a big impact on the success or failure of meeting your equipment’s operational expectations. As an equipment builder, you expect your OEM pressure measurement instruments to be accurate. That’s a given. But even if it’s not top of mind immediately, what you want even more than accuracy is long-term repeatability. Ashcroft has been manufacturing pressure measurement instrumentation since 1852. So, we understand how challenging it can be to find high-quality, accurate and cost-effective instruments that go the distance to deliver consistent performance over the long term. This is especially relevant for sensors used in tough conditions involving exposure to wide temperature ranges, high cycle life expectations and vibration. Each of these could affect the accuracy and repeatability of critical pressure measurements. This article will explain the elements of an OEM pressure sensor, clarify the difference between repeatability and accuracy, and show you what makes a sensor accurate and repeatable over time. When you are done reading, you will know the key factors to look for when purchasing a high-performance pressure sensor for demanding cycle life conditions which can be common to many applications.

If you are an Original Equipment Manufacturer (OEM) looking to optimize cost and streamline installation processes, you’ll want to learn more about ratiometric (RM) output pressure transducers. These highly efficient and cost-effective solutions are engineered to accommodate a wide range of applications, such as off-highway vehicles (OHV), motorsports, and mobile hydraulic systems. I recently published a blog that reviewed three key factors to consider when selecting an OEM pressure transducer: reliability, durability, and repeatability. Ratiometric output transducers incorporate all three factors and more. In this article, you will learn how these pressure measurement instruments can help you achieve cost savings while ensuring seamless integration and enhanced performance in demanding environments.

Pressure transducers are used to measure pressure levels in some of society’s most critical OEM applications, from mobile hydraulics to pump monitoring to railroad pneumatics, performance racing, and more. Without an efficient, accurate pressure transducer, it’s impossible for manufacturing processes to run smoothly and predictably. In the worst cases, uncontrolled or unmonitored pressure levels can put operators and equipment at risk. Ashcroft has many years of experience designing pressure instruments for a variety of settings. We believe the key factors to consider when selecting an OEM pressure transducer are reliability, durability, and repeatability. In this article, we’ll review these features in a little more depth, discuss some of the most common applications for these devices, and compare the specific options Ashcroft offers, including the G2 and the S1 models. When you are finished reading, you will have a solid understanding of what to look for when selecting a pressure transducer for your application, the similarities and differences between these two models and be ready to make a decision about which is best for you. .

In semiconductor applications, your pressure instrumentation needs to stand up to the conditions as well as meet high-purity standards and regulations. Ashcroft's line of fluoropolymer pressure transducers provides reliable pressure measurements for your semiconductor applications. How do you know which of these transducers is the right one for your application? This blog will compare Ashcroft’s ZL91, ZL92 and ZL95 pressure transducers and discuss their features and benefits to help you find the best solution for your needs.
