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.

Pressure gauges are often used in challenging environments where they could be exposed to extreme temperatures that may damage them or impact their accuracy. These extreme temperatures can come from a variety of sources such as the surrounding environment (ambient temperature), or the temperature of the process media being measured (media temperature). How do you minimize the effects of temperature on your instrumentation and protect your pressure gauges from damage? Read on to learn the effects that temperature can have on pressure gauges and their performance. Plus, you will gain insights into how you can address these issues to keep your gauge working at peak performance.

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.

Temperature sensors are key components in helping to ensure a safe and reliable application. RTDs and thermocouples both provide accurate and repeatable temperature measurements for your process. But, how do you know which sensor is the best one to use in your application?
