pressure transducers | pressure sensors | OEM | CVD

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 transducers | pressure sensors | Freeze protection

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.

November 6th, 2023

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.

October 9th, 2023

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. .
