INS Written Final Flashcards Study
Guide Questions and Answers
What is a Heat Exchanger? - ANSWER>>Any piece of equipment that tranfers heat
from one MATERIAL to another
Intrinsically Safe - ANSWER>>A protection for the safe operation of electrical
equipment in explosive or abnormal operating conditions
What color is the negative wire of a THERMOCOUPLE? - ANSWER>>RED, positive
is the non-red wire
What does CR1 stand for on a P&ID Diagram? - ANSWER>>Control Relay 1
MAC Address - ANSWER>>Media Access Control address - Machine's physical
address
Thermowell - ANSWER>>A closed tube designed to protect temperature
instruments from process conditions. They also allow for maintenance to be
performed without draining the process fluid.
Split Range Control - ANSWER>>The output of a controller is split between two or
more final control elements.
What does an O2 sensor in a Boiler Stack do? - ANSWER>>Ensures the boiler is
running efficiently, and ensures there is a proper fuel to oxygen ratio.
What is Reynold's Number and what is it used for? - ANSWER>>Ratio of inertial
forces to viscous forces. Used to measure how laminar or turbulent fluid flows
, What makes a needle in a gauge move? - ANSWER>>Bourdon Tube
A digital input of a PLC is used for a counter and is activated every 20ms, how do
you make the PLC not miss a count? - ANSWER>>Use a high speed counter
module
What is a proximity sensor? - ANSWER>>A sensor able to detect objects without
physical touch
What is a Fluke Linkrunner and what does it do? - ANSWER>>A network
multimeter used for troubleshooting and testing the physical and data link layers
of a network.
What is an actuator? - ANSWER>>Provides power and motion to manipulate parts
of a valve or damper. Used to control fluid flow
How do you convert psiA to psiG - ANSWER>>psiG = psiA + 14.7
Turbulent Flow - ANSWER>>An irregular pattern of flow with random variations in
pressure
How should a MAG Flow Meter be mounted? - ANSWER>>Vertically, Upward
Viscosity - ANSWER>>A fluid's resistance to flow
BTU (British Thermal Unit) - ANSWER>>The amount of heat required to raise the
temperature of one pound of water by one degree Fahrenheit
