Scanner

Scanner

A Scanner, also known as a Temperature Scanner or Process Scanner, is a multi-channel monitoring device used to sequentially or simultaneously display and record multiple process variables like temperature, pressure, flow, or level from multiple sensors or transmitters. It’s commonly used in industrial process control, test benches, and data acquisition systems.
