In process control terminology, continuously variable values which change without distinct increments, such as temperature, pressure, or level are correctly referred to as what type of values?

Correct Answer: Option D — analog values

Analog values represent continuous physical parameters such as temperature, pressure, or tank levels. Unlike digital values, which are discrete binary states, analog signals vary smoothly over a range. These are critical for monitoring shipboard machinery performance and are typically converted to standard 4-20mA signals for transmission to control systems.
