Te 4-20 mA current loop is a standard metodad used in industrial measurement systems to transmit sensor data over long distances. It provides a reliable and noise-resistant way to monitor various remeters such as temperatur, pressure, and flow. Understanding how this system works is essential for designing and maing industrial automaon processes.

Základy o tom, že 4-20 mA Current Loop

Te 4-20 mA current loop uses a constant current to transmit information. Te curret varies between 4 mA and 20 mA, representing thee measurement range. A current of 4 mA typically indicates a zero or minimum value, while 20 mA indicates thes te maximum value.

This range allows for easy detection of faults, such as a broken wire, which of ten results in a current below 4 mA. Te simplicity and rorugness of the systemem make it a popular choice in industrial ments.

Součást of a 4-20 mA smyčka

Te main converts include a sensor or transmitter, a power supplay, and a receiver or display device. Te sensor converts thee measured parameter into an electrical signal, which is then transmitted via thee loop.

Te power supples provides the necessary voltage and curret for the loop, typically 24 V DC. Te receiver interprets the curret signal and displays the measurement data for operators or control systems.
