About this document
Overview of 4-20mA Transmitters by Ramius Hamdani is a document available to read on EtoBox.
- 4-20mA current loop transmitters are used in industrial automation and building automation to transmit sensor signals over long distances. They work by using a constant current signal between a transmitter and receiver. - The 4mA level represents 0% input and 20mA represents 100% input. This allows fault detection for signals below 4mA or above 20mA. - Current loops are essentially lossless over long distances unlike voltage signals, which would attenuate. Current is also equivalent at any point in the
