Answer:D
What is a loop calibrator used for?
A. Calibrating temperature sensors B. Calibrating pressure sensors C. Calibrating flow sensors D. Calibrating current loops
Explanation: A loop calibrator is a device used to calibrate and test current loops, which are commonly used in process control applications. It can generate and measure milliamp signals, which represent the current flowing through the loop. Loop calibrators can be used to check the accuracy of sensors, controllers, and other devices connected to the loop.
