When working with critical processes in power generation, chemical manufacturing or food processing, one of your primary challenges is ensuring accurate temperature measurement. The wrong sensor could lead to reduced performance, safety concerns or even equipment failure. That’s why selecting the correct temperature sensor for your application is so important. As a recognized leader in pressure and temperature measurement instruments, Ashcroft has been helping industries worldwide make informed decisions for over a century. In this article, you will learn about two types of temperature sensors, how they work and their respective advantages and disadvantages. You will also receive guidance on selecting the most suitable sensor for your specific needs.

Finding the right temperature sensor at a price that fits your budget can be a challenge. During an industrial project for a critical application that required both RTDs and thermocouples (two common types of temperature sensors), the buyer's main concern was cost. He had assumed these instruments were priced similarly. The reality is not all applications are the same and not all temperature sensors are created equal. A sensor designed to measure air temperature in a room is vastly different from one built to withstand 1,400 °C in a heat-treating furnace. The type of sensor, the environment it's used in and the level of accuracy or durability required can all influence the price. As a trusted leader in temperature and pressure measurement, we created this article to help you understand what really goes into the cost of a temperature sensor. Read this article to learn the top five cost drivers for temperature sensors so you can make a confident, cost-effective decision. By identifying what matters most to your application, you can avoid overpaying for unnecessary features—and feel confident that you’re selecting the right tool for the job. When you are done reading you will have a better idea of how much you can expect to pay for these instruments. Plus, you will see additional resources that can address other questions you may have about temperature sensors.

In harsh process environments, even the most durable components can degrade over time—especially thermowells, which are your first line of defense for temperature sensors. Exposure to corrosive chemicals, high-velocity flow or abrasive media can wear down thermowells, risking measurement accuracy and system reliability. That’s where coated thermowells come in. As a trusted leader in temperature instrumentation, Ashcroft helps engineers extend equipment life and ensure process stability by offering different coatings for specific conditions. In this article, you’ll learn how thermowell coatings work, the different types available and how to choose the best option to protect both your instruments and your process.

This article was originally published on May 31, 2023, and updated on June 11, 2025. As industries move to adopt hydrogen as a clean energy source, the demand for robust pressure sensing technology has never been greater. But hydrogen introduces unique challenges. For example, many hydrogen applications have processes that can cause hydrogen ion diffusion. This can lead to hydrogen permeation and embrittlement, which can cause premature failure of your measurement instruments. Ashcroft is a leading authority in pressure and temperature instrumentation, with decades of experience designing solutions that meet the unique demands of hydrogen environments. We wrote this article in response to a question that came into our help desk. Read on to learn about hydrogen permeation and hydrogen embrittlement, why they matter in hydrogen applications and how several Ashcroft® pressure transducers are uniquely engineered to mitigate each of these issues. You will also find additional resources that may address other questions you may have about hydrogen applications and selecting the right instrumentation for your system.
