持续温度的精确测量are vital to several industrial processes in fields from construction to energy to manufacturing. And while there are many ways to measure temperature of gas and liquid, thermocouples are among the most popular thanks to their simple design and versatility. But over time, a thermocouple’s performance may tail off for any number of reasons. Two of the most common are drift and elevated temperature.

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.

There are many instruments used for temperature measurement, but electrical temperature sensors tend to be the most common method. A resistance temperature detector or RTD temperature sensor converts the measured temperature value into an electrical signal. But do you know how an RTD actually works? This article will discuss RTD sensors, their function and how they can help provide accurate temperature measurements for your application.

Temperature can be measured with a variety of methods. Glass thermometers, resistance temperature devices (RTDs), bimetal instruments, gas expansion (gas-actuated) thermometers and infrared radiation, to name a few. Each offers a unique set of advantages for specific applications. Another extremely common temperature measurement device is the thermocouple. Its simple design makes it remarkably versatile, reliable and cost-effective. But how does a thermocouple work? This article will describe the function of thermocouples, the different types and their material composition.

I was recently involved in an industrial project for a client’s critical application that required RTDs and thermocouples. The buyer’s main concern seemed to be the cost, assuming that all temperature sensors probably cost the same. However, not all applications are the same, and not all temperature sensors are created equal, so prices can vary. The prices of RTDs and thermocouples are determined by a number of factors, including the applications for which they’re being used and the temperatures in which they’re working.
