pressure transducer | pressure sensors

Pressure transducers are important instruments that are used to measure air, gas or liquid pressure in many industrial applications. They work by measuring pressure at various stages of a process and converting the measurement into an electrical signal, which is used to monitor and control the overall system. Ashcroft has been making pressure transducers for decades and one question we are often asked is whether these instruments can be installed in any orientation. While the short answer is “yes, they can,” there are factors to consider before you install your transducers. Read this article to learn how transducers work, the effect that changing the orientation may have on the instrument’s accuracy and how position errors can be fixed. You will also be directed to additional resources that can help answer other common questions about pressure transducers.

water & wastewater | pressure sensors

According to the Environmental Protection Agency (EPA), groundwater serves as a crucial resource for half of the U.S. population. Reliance on this vital natural resource is especially significant in regions with scarce rainfall, limited surface water availability, or high agricultural demands and population. As a leading manufacturer of pressure and temperature instrumentation, Ashcroft understands the challenges of protecting this vital resource. In this article, you will learn about submersible pressure transmitters and how they are used to monitor water levels and provide essential information to water management personnel. You will also see examples of four common applications where submersibles are used and some challenges these instruments may encounter while in use. When you are done reading, you will find additional, related resources that may be of interest when you are ready to go beyond the basics of this topic.

low pressure | pressure sensors | critical environments

Measuring very low-pressure in controlled environments like data centers, isolation rooms, labs, and operating rooms, for example, is challenging because they must maintain a very specific and very controlled atmosphere. If these environments are compromised in any way, it puts the people and the equipment you are protecting at risk. That's why you must ensure your pressure measurement instrumentation meets the specified guidelines for accuracy and reliability. As a product manager at Ashcroft, I have 26 years of industry experience, including the past eight years working exclusively on low-pressure sensing technology. In this article, you will see how we define 'very low' pressure, see examples of controlled environments where low-pressure measurements are required, and learn how pressure is measured in these applications. You will also gain a better understanding of the impact temperature has on pressure measurement and what to look for in a pressure measurement instrument to ensure your controlled environment stays secure. When you are done reading, you will also be directed to additional articles and resources that may be of interest for other questions you may have.

March 25th, 2024

Chemical vapor deposition (CVD) is a process used to create highly advanced, field-proven, thin film technology for pressure sensors that are used in mid- to high-pressure applications. These sensors are designed to deliver consistently accurate, reliable and repeatable pressure measurements under some of the most difficult conditions. If you are an Original Equipment Manufacturer (OEM), you know that your operations are among the most rugged in any industry. As such, you require instrumentation that is both consistently accurate and able to meet the shock, vibration, temperature and high cycle demands of your applications. As a recognized leader in pressure and temperature instrumentation, Ashcroft pressure transducers offer OEM customers everything they need in a high-quality pressure transducer. Our CVD-based sensors are produced in Japan by our parent company, Nagano Keiki, and are used in many of our pressure sensors, especially those needed for OEMs. In this article, you will learn how CVD technology works in the manufacturing process, applications where you will find this technology and the benefits it offers to OEM manufacturers and others who use it. When you are done reading, you will see other related resources that will help you learn more about the pressure instruments that incorporate CVD technology and the applications where they are used.

pressure gauge | Pressure Instruments | pressure sensors

If you are working in an industry that requires instrumentation to measure and monitor pressure in a system, you already know the basic principle of pressure measurement. According to Pascal's Law, pressure is proportional to the force and inversely related to the area over which the force is applied. In other words, pressure is equal to force per unit area. Figure 1: Pressure Equation. Different systems and applications require different types of pressure measurement instruments. For example, mechanical pressure gauges may be used as visual indicators of pressure levels throughout a process. Conversely, pressure transducers or transmitters can sense changes in a system’s pressure and send a signal to a control room. If you are new to your industry and want to learn more about pressure instruments, this article will give you a high-level overview of how to read pressure, definitions of pressure types and the instruments used to measure pressure. Ashcroft is a recognized global leader in pressure instrumentation and is a trusted authority for related information. When you are done reading, you will find additional resources related to pressure measurement that may interest you.

pressure transducers | pressure sensors | Freeze protection

By: Todd McPadden
January 16th, 2024

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.
