Answer:D
What is the typical range of an instrument loop transmitter?
A. 0 to 5 VDC B. 0 to 10 VDC C. 0 to 20 mA D. 4 to 20 mA
Explanation: The typical range of a 4 to 20 mA loop transmitter is from 4 mA to 20 mA, which corresponds to the minimum and maximum values of the process variable being measured. This range is commonly used in industrial applications because it provides a robust and reliable signal that can be transmitted over long distances.
