Consistently accurate temperature measurements are vital to several industrial processes in numerous industries from construction to energy to manufacturing. Although many instruments can measure the temperature of gas and liquid in these processes, thermocouples are among the most popular thanks to their simple design and versatility. Over time, however, the thermocouple’s performance may tail off for any number of reasons. Two of the most common are drift and elevated temperature. As a leading authority in temperature measurement instrumentation, we help customers understand the factors to consider when selecting instruments and the steps needed to keep systems running efficiently. If your process includes temperature measurement with a thermocouple, this article will explain why it is important to calibrate your instrument and how to do it. You will also get access to helpful resources that can help you gain deeper knowledge on the subject of temperature sensors.

In the chemical and petrochemical industry, measuring and monitoring pressure is critical to ensuring your operation runs safely and efficiently. Inaccurate pressure measurements can have serious consequences, including employee injury, equipment loss, environmental issues and costly downtime. That’s why it is essential to use instruments engineered to withstand the severe demands of chemical processing operations. Ashcroft has been making accurate and reliable pressure and temperature measurement instruments for more than 170 years. During that time, we have seen how pressure gauges perform in the most demanding conditions and have become an industry authority across the globe. In this article, you will learn about the unique challenges pressure gauges encounter in chemical and petrochemical operations and gain a better understanding of how to ensure your gauge is safe to use in these demanding applications. When you are done reading, you will have access to additional articles and resources to deepen your knowledge even further.

Maintenance, reliability, process and Health Safety Environment (HSE) teams rely on accurate and stable temperature measurements to meet their goals. Thermocouples, new out of the box, are a critical tool for these measurements that help plant personnel maintain safe and efficient operations. Today, instrument designers use a wide array of thermocouple types, such as Type K, Type E and Type T to measure temperatures in applications ranging from cryogenic temperatures of -196 °C to the extremes of 1700 °C. This article will discuss how thermocouple calibration offers added benefits that promote process improvements and support compliance requirements. When you are done reading, you will also find additional related resources that can help you gain more insight into these important instruments.

Working in the oil and gas or chemical industries means your process and your people are exposed to dangerous acids and chemicals. Chemicals such as hydrofluoric acid and others can create dangerous conditions and corrode certain materials, which could result in hazardous leaks. That's why it is imperative to select pressure and temperature instrumentation that can safeguard your entire operation from the potentially damaging effects of these applications. While dangerous acids have been safely used in industrial applications for many years, specifying proper pressure instrumentation with the appropriate wetted materials for these locations, requires unique expertise. That's where Ashcroft can help. With decades of experience in pressure and temperature instrumentation for the process industry, we have guided customers to the information they need to ensure they are choosing the safest instrumentation for their acid application. This article will discuss the safety concerns for harsh acid applications and what types of pressure instruments can best handle these challenging working environments. When you are done reading, you will also find additional resources that you can use as a reference for this topic.

The chemical industry manufactures a wide range of chemical and material products for industries that require durable and reliable measurement and monitoring technology for their production. You need accurate and reliable measurement instruments that can stand up to harsh chemical environments. Misapplication or failure of instrumentation can lead to severe consequences like equipment loss, employee injury and environmental damage, so it is essential to use instruments engineered to withstand the severe demands of chemical processing operations. This article will discuss some factors to consider when selecting the best pressure and temperature instrumentation for your chemical application.
