These environments pose significant challenges, such as extreme pulsation and vibration, which can lead to equipment failure and safety hazards. That's why ensuring your gauge is designed to withstand these conditions is so important. Since 1852, Ashcroft has been a trusted authority in pressure measurement, providing reliable solutions for demanding applications. Read this article to learn about common uses for ultra-high-pressure gauges, the standards they must follow for system and operator safety and considerations for selecting a pressure gauge for your needs. You will also be directed to additional resources to help you deepen your knowledge of relevant pressure gauge topics.

If you are using a pressure transducer (also known as a sensor) to measure liquid, gas or air pressure in a critical environment, OEM application or high-purity manufacturing process, you need to have confidence in the accuracy of your instrument. That confidence will be tested if there is an offset in the output of that instrument at zero and/or span. However, if you understand the reasons behind why offset can occur and what you can do to address it, your confidence will be restored. Ashcroft, an industry leader in pressure measurement instruments, has consistently demonstrated reliability and excellence in the field of pressure measurement instrumentation. That's why we are often asked to share our expertise and shed light on topics like this one. Read this article to learn how transducers measure pressure, possible causes of offset in the output of your sensor and what you can do to ensure your sensor is providing you with an accurate pressure measurement. You will also have the opportunity to deepen your knowledge through additional articles and resources available to you.

Diaphragm seals, also known as isolators, are commonly used to help safeguard the wetted parts of pressure measurement instruments, such as sensors (transmitters and transducers), gauges and switches, from corrosive chemicals in your system's pipes. In some instances, however, diaphragms are also used to protect the instrument from large particles that could potentially obstruct the process connection. As a business development leader at Ashcroft – a leader in pressure instrumentation – I frequently address these concerns in low-pressure applications. Read this article to learn about the factors to consider for using a diaphragm seal in your operation and to use them on different types of instruments (mechanical or sensor) to keep your system flowing. You will also see additional resources you can use as a reference to deepen your knowledge of these isolating instruments.

The challenge is finding the best instrument for your specific application at a cost that aligns with your budget. Having spent over 20 years in the pressure sensor/transducer industry in roles related to product management and sales, I've gained firsthand knowledge of the numerous factors that affect pricing. In this article, you will gain insight into these cost drivers so you can make a more informed decision about your transducer purchase. Please note, we are purposely excluding automotive/appliance and process transducers/transmitters from this discussion, as their market and cost structures are unique. Also, for clarity, the term “pressure transducer” refers to the complete assembly of the pressure sensor and output board, which some industries might also call a pressure sensor or transmitter. In this article, "pressure sensor" will indicate the sensing element or technology itself, which is part of the full pressure transducer product.

This article was originally published on November 15, 2021, and updated on March 31, 2025 In your most challenging applications, prioritizing safety is critical. For instance, in environments with high oxygen levels, you need to ensure your pressure instruments are free of contaminants to prevent a fire. Even though oxygen itself is not flammable, it can cause other materials like dust, oils and lingering residue to easily ignite and burn with intensity. Cleaning for oxygen service is an effective safety precaution you can take to prevent this from happening in your application. As a product sales leader at Ashcroft, a leading authority in pressure and temperature instrumentation, I am often asked if we offer this service to our customers. The answer is yes, depending on the application. However, before you decide if it's right for you, take a few minutes to see what the service involves. Read this article to learn more about the benefits of cleaning for oxygen service and the process we use to be sure your instruments are safe to use in high-purity gas or pure oxygen systems. You will also see additional articles and resources that are relevant to pressure gauge selection and care.

Managing hydraulic systems in mobile construction equipment, fuel pumps, industrial machinery and automotive braking systems for example - is no easy task. Because these systems use liquids in various forms to generate power, the inherent pressure levels of hydraulics have to be properly managed. Otherwise, the consequences can include reduced performance, potential equipment damage, or even physical injury to system operators. That's where hydraulic pressure gauges can help. These instruments play a critical role in regulating pressure by monitoring levels in either a specified part or the entire system to ensure things are operating normally. The challenge is choosing the pressure gauge that will work best in your hydraulic application. As a pressure gauge product lead at Ashcroft - a recognized authority in temperature and pressure solutions - I have seen many scenarios where the wrong pressure gauges were selected and the impact that decision had on operations. Read this article to learn about the five pressure gauge features I consider most important for hydraulic applications so you can be confident about selecting the best option to meet your specific needs. Let’s get started.
