What is a Thermocouple?

Using thermocouple sensors to measure temperatures in industrial applications. Temperature measurement is one of the most common requirements for any industrial automation or digitally-monitored system. It is often necessary to detect the temperature of gases, liquids, and physical equipment components. The primary contact-based technologies for doing so are thermocouples (TCs), resistance temperature detectors (RTDs), and…

Trending Towards Green Machines

When wandering the plant floor, keep an eye out for energy wasting machines. Those running conveyors, rattling pumps and hissing air lines on idle equipment not only raise the decibel level in the plant—they also waste energy. With proper monitoring and analysis, machine energy use can be optimized, and these energy saving measures will also improve…
