Selecting the right pressure sensor can make or break a control loop—I’ve seen otherwise well‑tuned systems stumble simply because the sensor wasn’t built for the heat. Temperature, more than almost any other factor, shapes accuracy, lifespan, and safety. In the following sections, I’ll lay out how standard and high‑temperature pressure sensors differ in design and materials, where each excels, what to compare (from operating range and stability to construction, maintenance, and cost), and how to match a sensor to your process. I’ll also touch on what’s next for sensor tech and where smart, connected designs are headed. Understanding the Fundamental...
