How to simulate thermocouple signal
WebJul 19, 2012 · Thermocouples produce a voltage (or loop current) that is proportional to the difference in temperature between the hot junction and the reference junction. If you want to know the absolute temperature at the hot junction, you must know the absolute temperature of the reference junction. WebThe 4-20 mA current loop is the dominant standard in many industries. It is the simplest option to connect and configure. It uses less wiring and connections than other signals, greatly reducing initial setup costs. Better for traveling long distances, as current does not degrade over long connections like voltage.
