23 paź 2024 · The remote transducer on the left regulates the loop current in proportion to the quantity being measured, with 4mA representing a zero reading and 20mA full scale. The sensor converts the current back to a voltage for display or other use.
This design allows the injection of FSK-modulated digital data into the 4- to 20-mA current loop for HART communication. External protection circuitry is deployed in-place for compliance with regulatory IEC61000-4 standards, including EFT, ESD, and surge requirements.
I'd like to run some tests by using 4-20mA sensors outputs, by somehow connecting them to my PC (and eventually run some analysis on the collected data). I'm looking for a converter (that can perhaps be plugged in via USB), or some other interface method to my PC / Laptop.
The 4-20 mA current loop has become the standard for signal transmission and electronic control in most analog control systems. A 4-20mA current loop circuit is shown in Figure 1.
4-20mA T Click is a compact add-on board that serves as a transmitter in a 4-20mA current loop standard. This board features XTR116, a current loop transmitter from Texas Instruments. The XTR116 provides accurate, current scaling and output limit functions.
27 maj 2022 · 4-20 mA receiver design is available as printed circuit boards or integrated circuits. Regardless of the design type, the receiver circuit should offer high reliability and high conversion accuracy at low design and manufacturing costs.
19 lip 2017 · The most common standard is the 4-mA-to-20-mA current loop, and here we’ll take a look at how it came to be, how it works, and how you can leverage this basic process control...
