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.

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. .

Harsh applications and environments call for equipment that can meet particular demands. For these types of demands required by Original Equipment Manufacturers (OEMs), Ashcroft is excited to announce the release of the S1 pressure transducer. Designed for large-volume manufacturing, the new Ashcroft S1 is a high-quality pressure transducer at an economical cost that is available with quick lead times. Specially made for applications that include mobile hydraulics, performance racing, agriculture and refrigeration, the S1 is a reliable solution for harsh environments.

Your pressure sensor is a vital component of your equipment or system. When properly specified your system will operate safely and to expected performance levels over the design life of the system or equipment, but only if you have the right sensor that’s appropriate for your application. The wrong pressure sensor can result in equipment damage, worker injury or out-of-specification measurements. So, how can you ensure you choose the right one?
