General Questions - Flashcards (1)
Here it is another initiative by epc-school. Flashcards are displayed below. Try answer these in comment section. Correct answers will be displayed tomorrow's blog-
Q1: Most commonly used algorithm for digitally executing PID control; the result of taking the difference between two successive iterations of the position algorithm.
Q2: Device for detecting the presence or absence of bulk solids.
Q3: Refers to the feedback controller in the outer loop whose output sets the setpoint for the inner loop controller.
Q4: Device that measures the relationship between electrical resistance and temperature.
Q5: System in which only a number of states are allowed. In binary digital, only two states (0 and 1) are allowed. In the decimal system, only ten states (0 through 9) are allowed.
Q6: Design in which a guide bushing or bushings are fitted into the body, bonnet, and/or bottom flange so as to guide a plug's post.

Instrumentation Common Questions -3
I for Instrumentation
Q: What are Analog Input/output & Digital Input/output?
4-20 mA signals from instrument (transmitters) are analog input to control system.
4-20 mA signals to instrument (I/p & electro pneumatic positioner) are analog output from control system.
