Shema — Tokovaja Petlja 4 20 Ma

Typically 24V DC to drive the current through the loop.

The 4 mA floor allows the system to distinguish between a "zero" reading and a broken wire (0 mA). 🛠️ Main Components A functional circuit consists of four essential parts: Sensor/Transducer: Measures the physical variable. shema tokovaja petlja 4 20 ma

The system translates a physical measurement (like pressure or temperature) into a current signal between 4 mA and 20 mA. Represents the 0% or minimum value of the range. 20 mA: Represents the 100% or maximum value of the range. Typically 24V DC to drive the current through the loop

Two wires for power and two separate wires for the 4-20 mA signal. The system translates a physical measurement (like pressure

I=4mA+(16mA×P)cap I equals 4 m cap A plus open paren 16 m cap A cross cap P close paren Example: At 50% capacity, the loop should read . If you are designing a specific circuit, let me know: The sensor type you are using. The distance between the sensor and the controller.
